Welcome to Gutenprint 5.0.0-rc1!  Please read these release notes
carefully.

Gutenprint, formerly named Gimp-Print, is a suite of printer drivers
that may be used with most common UNIX print spooling systems,
including CUPS, lpr, LPRng, or others.  These drivers provide high
quality printing for UNIX (including Macintosh OS X 10.2, 10.3, and
10.4) and Linux systems that in many cases equal or exceed proprietary
vendor-supplied drivers in quality and functionality, and can be used
for demanding printing tasks requiring flexibility and high quality.
This software package includes the Print plug-in for the GIMP and
Ghostscript and CUPS drivers, as well as Foomatic data.

The package has been renamed in order to clearly distinguish it from
the GIMP.  While this package started out as the Print plugin for the
GIMP, it has expanded into a collection of general purpose printer
drivers, and the Print plugin for the GIMP is now only a small (but
important) piece of the package.  Furthermore, the name Gutenprint
recognizes Johannes Gutenberg, the inventor of the movable type
printing press.  Finally, the word "guten" means "good" in German.

Gutenprint 5.0.0-rc1 is the first release candidate of Gutenprint 5.0.
It is based on the Gimp-Print 4.3 series that has been in development
for over three years, and includes many improvements over the very
popular 4.2 series.  This release is believed to be quite stable, but
further testing is required before final release.  We believe this
release to be stable enough for day to day use, and encourage people
to test it and report their results.

Gutenprint currently contains over 200 drivers supporting in excess of
600 printer models.

The Print plug-in for the GIMP requires the GIMP 1.2.3 or above on the
1.2 line (1.2.5 is recommended), or the GIMP 2.0 or above.  You may
need to install packages named "gimp-devel", "gtk-devel", and
"glib-devel" (or similar equivalents) on many systems.  This plug-in
will work with any printing system, and offers a comprehensive user
interface to control all aspects of the printing process.

The CUPS driver requires CUPS 1.1.15 or higher.  You may need to
install a package named "cups-devel" or similar on many systems.
Please the rest of the release notes, in particular the Exceptions and
Workarounds, for full details on installation, as there is an
important caveat.  CUPS is the printing system used on Macintosh OS X
10.2 and above, and many other systems use it.  The combination of
CUPS and Gutenprint provides a flexible, general purpose printing
system capable of producing the highest quality output with any of the
printers supported by this package.  We strongly recommend using CUPS
with Gutenprint as a general-purpose printing solution.

The Ghostscript driver requires GNU Ghostscript 6.53 or higher, ESP
Ghostscript 7.05 or higher, or AFPL Ghostscript 7.04 or higher.  It
uses the IJS package included with these versions of Ghostscript to
create a driver that may be built much more easily than traditional
Ghostscript drivers.  The options for this driver are very complex,
and it is normally used with the Foomatic driver integration system.

Users of Macintosh OS X 10.2 (Jaguar), 10.3 (Panther), and 10.4
(Tiger) can use this package, as the printing system is based on CUPS.
For ease of installation, a pre-built package with installer is
normally supplied a few days after the release of the source package.
We highly recommend that OS X users use the pre-built package rather
than attempt to build it themselves.

NOTE: This package will not work with any version of OS X 10.0 and
10.1 (such as 10.1.5), as those systems do not use CUPS as their
printing system.  This is NOT going to be fixed; you must upgrade to
at least OS X 10.2 in order to use this package.  The reason why is
that OS X 10.2 and above use CUPS as the basis of the printing system.
OS X 10.0 and 10.1 use a different system that would require a
separate driver, and we do not plan to write that driver.

The README file included with this package provides full instructions
on building and installing Gutenprint.

These release notes contain the following sections:

1) Changes from 5.0.0-beta4 to 5.0.0-rc1
2) Overall changes from 4.2 to 5.0.
3) List of supported printers
4) Printer-specific notes

================================================================

* Major changes between Gutenprint 5.0.0 beta 4 and Gutenprint 5.0.0
  release candidate 1:

  1) Color correction is greatly improved, particularly for Epson
     printers.  The following general and specific improvements have
     been made:

     * The default gamma for all Epson printers has been increased to
       resolve long-standing issues with overly dark prints.  The user
       gamma adjustment is specified as a correction, so the default
       value of 1.0 will yield correct results.

     * Luminosity (darkness) correction has been simplified and
       improved by performing correction only on the color component,
       without adjusting the gray component.  This improves dark cyans
       and greens in particular, and generally yields smoother tonal
       changes.

     * Red and blue generation for the Epson Stylus R800 and R1800
       (and for any future printers) has been completely revamped.  It
       is now done by using per-channel curves.  This improves control
       over the output and allows ink combinations that could not be
       generated with the previous code.  The most notable effect is
       improved magenta.

     * Greens have been improved on all Epson printers and are now
       considerably more saturated and less yellow.

     * Black generation has been improved on all printers,
       particularly Epson printers using Ultrachrome (R) inks.

     * Photo (light cyan and light magenta) ink generation has been
       improved on many Epson printers.

     * Composite gray generation is now done by adding in CMY inks
       rather than subtracting out the gray component.  This separates
       the gray balance from the per-channel ink density, permitting
       much better color saturation for certain printers with
       unbalanced inks.  In particular, the Epson R-series printers
       can now generate much better orange, yellow, and green without
       sacrificing neutrality of grayscale.

     * The operation of the Bright Colors color correction mode has
       been changed, and is now much closer to the operation of High
       Accuracy.  The main difference is that highly saturated colors
       now clip rather than taper off toward full saturation.  This
       will yield improved color brilliance with some loss of detail
       in certain cases (particularly bright greens).

     * A new Correct Hue Only mode has been added that corrects ink
       hue without adjusting darkness.  This permits achieving greater
       color saturation without losing hue accuracy, although many
       colors will be too dark in this mode.

  2) A problem that could on rare occasions cause blank areas on photo
     printers has been fixed.  The problem was more likely to be
     observed when printing in 16-bit mode.

  3) CUPS PPD files are now built with translations enabled.  If you
     do not want translated PPD files, configure the package with

     ./configure --disable-translated-cups-ppds

  4) The Canon SELPHY CP-600 dye sublimation printer has been added.

  5) The Epson Stylus C82, C84, and C86 now use black ink with glossy
     paper.  The ink in these printers has been reformulated and is
     now compatible with glossy paper.

  6) The Epson Stylus CX3650 now prints correctly (previously there
     were minor vertical offset problems, yielding slightly blurry
     prints).

  7) New printing resolutions have been added for certain Epson
     printers:

     * 720 DPI high quality has been added for all but the very oldest
       Epson printers, and 1440x720 DPI highest quality has been added
       for all Epson printers with an upper resolution limit of
       2880x720 DPI.  We have received reports that 1440x720 highest
       quality, which was present in Gimp-Print 4.2, often produces
       better output than 2880x720 while requiring less computation.

     * 2880x2880 DPI resolution has been added for the Epson Stylus
       C86 and similar printers, such as the CX6600.  While this is
       not likely to yield a great improvement over 2880x1440 DPI,
       this may yield some improvement for certain kinds of line art
       with very fine detail.  In general, there is little advantage
       to be had from any resolution above 1440x1440 DPI with this
       printer.

  8) The Epson Stylus RX425 is now explicitly supported.

  9) Some problems with PPD file generation using cups-genppdconfig
     have been fixed.  In particular, PPD permission and ownership
     checks have been relaxed to permit operation on more systems.

  10) Debian packaging has been removed from this release.  Debian
     packaging will be handled by the maintainer outside of the
     release.

  11) On systems supporting shared library versioning, the shared
     library is labeled with the correct release version rather than a
     development version.


================================================================

Overall changes between Gimp-Print 4.2 and Gutenprint 5.0:

* General User-Visible Changes:

  1) In general, Gutenprint 5.0 is not compatible with Gimp-Print 4.2.
     Gutenprint 5.0 offers many new options (which are described
     separately below), and many options that are present in both 4.2
     and 5.0 function differently in the two releases.  In addition,
     the API is different.  Finally, the color correction is quite
     different, and profiles created against the 4.2 driver will not
     function well against the 5.0 driver.

  2) In addition to all of the printers supported in 4.2, a variety of
     Olympus and Sony photo printers are supported in this release.

  3) Options in the CUPS driver and GIMP plugin are now grouped
     according to function.  This work is still in progress, and
     further usability improvements are expected.

  4) Simplified bundles of settings are now offered for users who do
     not need to customize the settings.  The Print Quality and Image
     Type controls offer a variety of settings optimized for common
     printing tasks.  Both controls offer Manual Control settings for
     users who wish greater control over the output.

  5) Many of the color settings have changed effect.  We recommend
     starting with no color correction and making appropriate changes
     only as required.  Specific changes that you should be aware of
     include:

     * The default operation of the contrast setting has changed to be
       more in accord with standard practice.  In 4.2, reducing the
       contrast resulted in changing the black and white setting.  In
       5.0, reducing the contrast does not change the black and white
       settings.  As a result, it is possible to use the contrast
       setting to improve highlight and shadow detail by reducing the
       contrast.

       The old behavior is available by turning on the "Linear
       Contrast Adjustment".

     * The brightness control now behaves more appropriately,
       adjusting the image's overall brightness without changing the
       black or white points.

     * The Cyan, Magenta, and Yellow settings have been replaced with
       separate settings for gamma, density, and gray balance for
       Cyan, Magenta, Yellow, and Black.  The Cyan, Magenta, and
       Yellow settings in Gimp-Print 4.2 most closely correspond to
       the gamma settings in 5.0.

       The per-channel density settings do not affect the color
       correction.  They are applied after the color correction to
       scale the individual channels.  The per-channel gray balance
       settings adjust gray balance without affecting per-channel
       density settings, permitting better color saturation without
       compromising gray balance.

  6) The Uncorrected color correction mode is recommended for users
     who wish to use their own color (ICC or otherwise) profiles with
     Gutenprint drivers.  This will yield the maximum gamut and most
     uniform response.  If you are not using your own color
     management, you will generally get best results from the High
     Accuracy color correction setting.

  7) The old man pages, and src/ghost/README, have been withdrawn.
     These pages, and the Ghostscript README file, were based on the
     Gimp-Print 4.2 options, which were much less extensive than the
     current option system.  It is not practical to keep them up to
     date in any meaningful way.  Our recommendation is that people
     use either the native CUPS driver or Foomatic to manage options
     rather than attempt to create and manage printer queues by hand.

  8) The source browser in the documentation package has been
     removed.  This information, which consists of color-coded source,
     is of little interest to the vast majority of users and consumes
     a significant amount of space in the installation.


* New Functionality:

  1) This release offers a new curve data type, permitting very
     precise adjustments of output.

  2) This release offers many new output controls:

     + Balance (density) controls for each channel, in addition to the
       gamma controls present in 4.2.

     + Gray balance controls for the cyan, magenta, and yellow
       channels.

     + Black (GCR) transition, including the transition gamma and the
       upper and lower limits.

     + Transitions for photo (light cyan and light magenta) inks.

     + Transfer curves for each channel (cyan, magenta, yellow, black,
       and composite), allowing very precise control over the output.

     + Transfer curves for generation of additional channels where
       applicable, such as red and blue inks for the Epson Stylus
       Photo R800 and R1800.

     + Hue, saturation, and luminosity transfer curves.

     + Ink limit control.

     + The density control now permits setting density as high as 8.0,
       vs. 2.0 in 4.2.

  3) The Epson driver offers (almost) true full bleed for printers
     that support it (but see the limitations below).

  4) The PCL driver now offers duplex (two sided) printing support on
     appropriate printers.

  5) The package now includes support for a number of dye sublimation
     photo printers made by Olympus, Canon, Sony, and Fujifilm.

  6) The resolution list for Epson printers has been simplified; many
     redundant resolutions have been removed.

  7) Print head directional for Epson printers (unidirectional
     vs. bidirectional) is now a separate control.  In addition to
     contributing to the simplification of the Epson printer
     resolutions, this permits the choice of unidirectional
     vs. bidirectional at all resolutions.

  8) The Epson driver now allows printing directly to CD's on printers
     that support this functionality.  In addition, a choice of center
     hole size (16 mm or 43 mm) is now offered.  A fine adjustment is
     provided to permit control over positioning of the image on the
     CD.  This fine adjustment setting is not available in the
     Foomatic interface at present.

  9) The Epson driver now offers a choice of print head weave
     patterns.  In addition to simplifying the resolution choices for
     Epson Stylus Pro printers, this offers an additional control for
     fine tuning output quality.

  10) The Epson driver offers an Ink Set control for printers taking
     different choices of inks (such as the Epson Stylus Photo 2200,
     which offers a choice of Matte Black and Photo Black inks).

  11) The Epson driver permits adjusting the dot size if required to
     increase the amount of ink printed.  For example, if 1440x720 DPI
     is selected, but the density requested is very high, the printer
     will switch to using drop sizes appropriate for 720 DPI.  This
     option is disabled by default.

  12) Where practical, all controls offer a default setting for
     simplicity of operation.  This default value is intended to offer
     the optimal choice given the printer and its other settings.  For
     example, if "Automatic" is selected for print head direction, the
     print head motion will be unidirectional at high resolutions
     (since unidirectional usually produces better output), but
     bidirectional at low resolutions (for faster printing).

     The default is only offered for options that are not directly
     controlled by the user's action.  For example, there is no
     default choice offered for paper type, since the correct value is
     based on the paper type loaded by the user.  Similarly, there is
     no default for the input slot or ink set.

  13) Support for a variety of input types, in both 8 and 16 bit
     resolution, has been added.  Gutenprint can now handle input in
     grayscale, whitescale (inverted grayscale), RGB, CMY, CMYK, and
     KCMY in 8 and 16 bit resolutions for all output types.

  14) A new Threshold color correction mode has been added that
     produces either all-on or all-off of each color.  This is similar
     to the Monochrome mode in 4.2, except that it works for color as
     well as black.

  15) A new Desaturated color correction mode has been added that
     produces gray (desaturated) output using color inks.

  16) A new Density color correction mode has been added that corrects
     only for density.  This will normally produce excessively dark
     output.  However, applications that wish to use their own
     linearization curves may wish to use this interface to prevent
     Gutenprint from performing its own linearization.

  17) A new Raw color correction mode has been added that performs no
     correction whatsoever on the input.  This mode may be used by
     applications that wish to perform their own ink limiting and
     linearization, and use Gutenprint to perform dithering
     (screening) and output generation only.

  18) A new Predithered color correction mode has been added that
     combines the effects of Raw and Threshold.  This mode may be used
     by applications that wish to perform their own dithering and use
     Gutenprint to generate printer-specific output only.

  19) A new Correct Hue Only color correction mode has been added that
     performs partial color correction (adjusts hue, but not
     darkness).

  19) The escputil command, which performs various printer
     administration activities on Epson Stylus printers, has a number
     of improvements:

     * A new extended ink information command has been added.  This
       command, which is supported on printers with separate
       individual ink cartridges, prints additional information about
       the ink cartridge in addition to the amount of ink present.  On
       older printers, it simply returns the standard ink
       information.

     * Ink level detection now works on all known supported printers.
       Previously it did not work on some newer printers.  However, it
       is somewhat slower on these printers than it is on older
       printers that support the faster ink detection method.

     * Ink level detection now prints the correct ink color names for
       the printer model.

     * It is now no longer necessary to use the -u flag with certain
       printers in most cases.  The utility now autodetects the
       printer model and generates appropriate commands in all cases.

       If you supply a printer queue (with the -P option) rather than
       a raw device (with the -r option), you will still need to
       provide the -u flag, as the utility cannot detect the actual
       printer connected to a queue.  However, bidirectional commands
       (ink level, identify, printer status, and alignment) do not
       require the -u flag any more.

     * escputil now successfully detects ink level, printer model, and
       status even if the printer is out of ink.


* Changes to the Print plugin for the GIMP:

  1) A new plugin for the GIMP 2.0 is now provided.  At present it is
     experimental.  In the long run it will be distributed with the
     GIMP rather than with Gutenprint.  This is anticipated for the
     GIMP 2.2 release.

  2) The Print plugin for the GIMP 1.2 is now deprecated and will be
     withdrawn in 5.1 (the development release following 5.0).  The
     Print plugin for the GIMP 1.2 will continue to be supported in
     all 5.0 releases, but no new functionality will be added
     following the release of 5.0.0.

  3) The plugin now always displays the page preview with the top of
     the page at the top of the preview pane, rotating the image
     preview as necessary to display landscape or portrait mode.

  4) The positioning controls have been simplified.

  5) The printrc file format is different.  Gutenprint 5.0 can read
     printrc files created by Gimp-Print 4.2 and earlier, but it
     writes out the printrc file in a format that earlier versions of
     Gimp-Print cannot read.

  6) Printer queue discovery and command specification are greatly
     simplified over 4.2.  The plugin now offers a default printing
     command that is determined based on the characteristics of the
     system, and also offers the choice of printing to a file or using
     a custom print command for each printer defined in the printrc
     file.  The default printing command is correct whether the output
     is Postscript or not.

  7) The Print plugin now always displays all options relevant to
     what's being printed, enabling and disabling options as
     appropriate.

  8) If you are using an older version of the GIMP 1.2, and the GIMP
     is installed in a non-standard location on your system such that
     you cannot run configure in Gutenprint without using
     --with-gimp-prefix or --with-gimp-exec-prefix, please read item
     (10) in Exceptions and Workarounds below.  In addition, if you
     have both the GIMP 1.3/2.0 and the GIMP 1.2 installed on your
     system, you should read the same material.


* Changes to the CUPS driver:

  1) The CUPS PPD files now offer both fine and coarse adjustments for
     all color controls, permitting much finer control over output (in
     steps of .005 rather than .05).

  2) The CUPS driver refuses to function with PPD files created for a
     different version of Gutenprint or Gimp-Print, providing an error
     message indicating the problem.  This avoids problems caused by
     mismatches between the PPD files and the driver.  While
     mismatches are potentially not harmful in all cases, they could
     cause problems ranging from failures to print with poor
     diagnostic messages to incorrect results.

  3) The Gutenprint 5.0 CUPS driver can be installed concurrently with
     the 4.2 driver.  Both the PPD files and the driver carry
     different names from their 4.2 counterparts, permitting a
     parallel installation or gradual switchover between 4.2 and
     5.0-based releases.

  4) An update script (cups-genppdupdate.5.0) is provided to update
     PPD files between later 4.3 and 5.0-based releases, preserving
     option values where possible.  This script will not update PPD
     files based on Gimp-Print 4.2, or Gimp-Print 4.3 releases prior
     to 4.3.21.

  5) The CUPS driver now offers 16-bit printing as an option with ESP
     Ghostscript 8.15, and Apple Macintosh OS X 10.4 ("Tiger"), using
     the new Color Precision control.  Setting Color Precision to
     "Best" enables 16-bit printing if the system supports it; setting
     it to "Normal" uses 8-bit printing.  Setting Color Precision to
     "Best" has no effect if the version of CUPS does not support
     16-bit printing; in that case, "Best" is still 8-bit.

     The higher precision may improve results with certain source
     material, particularly if it contains smooth color gradients.
     The result would be freedom from banding, particularly in
     highlights where it might be visible with 8-bit color
     computation.  It may be somewhat slower than 8-bit printing.

  6) Due to the implementation of CUPS, it is necessary on some
     systems to link the programs associated with the CUPS driver (in
     particular, cups-genppd and rastertogutenprint) statically
     against the Gutenprint library.  Please see bugs 865253 and
     865265 for full details.

     This fix works correctly unless --disable-static (to disable
     building static libraries) is passed on the command line.
     Normally, only people packaging up Gutenprint for distribution
     use this option.  If you wish to use this option, please read
     item (9) Exceptions and Workarounds *carefully* for a full
     description of the problem along with suggested methods of
     procedure.


* Changes to the Ghostscript driver:

  1) The stp driver, a monolithic (traditional) Ghostscript driver
     used with Ghostscript 5.10, 5.50, and 6.51, has been withdrawn.
     The only supported Ghostscript driver is the IJS-based driver,
     for GNU Ghostscript 6.53 and above, ESP Ghostscript 7.05 and
     above, and AFPL Ghostscript 7.04 and above.

     This change was made due to the difficulty of supporting the
     monolithic driver and the complexity of building it.  The
     traditional monolithic driver architecture required that all
     drivers be compiled into Ghostscript, requiring that program to
     be recompiled whenever a driver is added.  This is a rather
     complicated operation that cannot easily be automated.  The IJS
     architecture, based on the open source HPIJS driver supplied by
     Hewlett-Packard for HP inkjet printers, allows for drivers to be
     compiled independently of the core Ghostscript.  A
     Gimp-Print/Gutenprint driver based on the IJS architecture was
     introduced into Gimp-Print 4.2.1 and 4.3.0, and has been
     recommended for use with Gimp-Print 4.2.2 and beyond.

     In addition to a greatly simplified build procedure and overall
     cleaner architecture, the separation between Ghostscript and
     driver imposed by the IJS architecture permits use of Gutenprint
     with AFPL Ghostscript with no license conflict.


* Changes to Foomatic data generation:

  1) The Ghostscript IJS driver now functions only with Foomatic PPD
     files created for the matching version of Gutenprint, providing
     an error message indicating the problem if an incorrect PPD file
     is used.  This avoids problems caused by mismatches between the
     PPD files and the driver.  While mismatches are not harmful in
     all cases, they could cause problems ranging from failures to
     print with poor diagnostic messages to incorrect results.

  2) The Gutenprint 5.0 Foomatic data and IJS driver can be installed
     concurrently with the 4.2 driver.  Both the PPD files and the
     driver carry different names from their 4.2 counterparts,
     permitting a parallel installation or gradual switchover between
     4.2 and 5.0-based releases.


* Quality Improvements:

  1) Color and tonal accuracy is greatly improved compared to 4.2
     while the gamut (range of printable colors) has been increased.
     This particularly improves the hue accuracy of red, magenta, and
     blue, and the tonal accuracy of cyan and green.  Most Epson
     printers have been fully tuned for the new color correction
     algorithms introduced for this release.

     The default gamma has been changed to produce lighter midtones
     with all Epson printers.

  2) The handling of variable drop sizes and photo inks (6 and 7 color
     printers) has been completely revised, with the result being that
     variable drop size printers with photo inks (such as most Epson
     Stylus Photo and Stylus Pro printers) give much more consistent
     results with fewer artifacts.  In particular, colors match
     correctly across all resolutions, which was not the case in 4.2.

     In 4.2, variable size drops and light inks were treated the same
     way; an "effective drop size" based on the relative size of the
     drops and the darkness of the inks was used to decide what kind
     of drop to print.  While this method has some advantages (it
     ensures that dark and light inks are never printed at the same
     place, and also that dark dots are optimally dispersed among
     light dots), it has some serious disadvantages as well: the
     properties of a small dark dot and a large light dot are not
     really the same, particularly when inks are mixed.  The
     combination of different drop sizes being used at different
     resolutions meant that the transition between light and dark inks
     differed depending upon the resolution chosen, and if more than
     one drop size was required at a given resolution, the transition
     tended to be quite marked.

     The new method of handling variable size drops and light inks is
     to first separate each of the four channels (cyan, magenta,
     yellow, and black) into the appropriate light and dark inks, if
     needed.  This separation is performed based on the relative
     darkness of the different ink sub-colors (such as light and dark
     cyan) and specific characteristics of the printer, ink type, and
     paper chosen.  Following this, each sub-color is screened
     separately, and the appropriate combination of drop sizes is
     chosen.

     The drop size selection in this release has also been changed to
     fill the page with as many small drops as possible before
     switching to larger drops.  This ensures that the largest number
     of the smallest possible drops is printed, which yields a
     smoother texture in the midtones.

     Finally, new dither algorithms described below allow drops of ink
     of different colors to be dispersed, avoiding clumping or
     overprinting of drops.

  3) The EvenTone dither algorithm has been extensively reworked in
     this release, offering many improvements.

     First, it has been rewritten to work correctly with variable drop
     size and photo printers.  This algorithm, which offers
     significant improvements over the standard Adaptive Hybrid
     algorithm, does not work optimally with variable drop sizes or
     photo printers in 4.2.

     Secondly, a variation called Hybrid EvenTone has been added.
     This dither algorithm perturbs the dot positions slightly to
     break up some patterning seen in standard EvenTone dithering in
     solid regions of pale tones, particularly when printing with
     black ink only.  This very slightly reduces the smoothness of
     texture in exchange for largely eliminating this undesirable
     patterning.  This algorithm is also expected to be more resistant
     to microbanding effects.

  4) The conversion between black and composite (CMY) gray has been
     improved in this release, yielding more neutral grays on most
     printers.

  5) Epson printers have been completely retuned, in most cases
     yielding much better density, more accurate gray scale, and
     darker blac on all paper types.


* Exceptions and Workarounds:

  1) Full bleed mode does not work completely correctly on most Epson
     printers at present.  Typically there is a small margin at the
     bottom of the page (1-2 mm) and possibly a very small margin at
     the top.  However, it works correctly along the left and right
     margins.  We do not have an estimated time for a fix.

  2) The Canon, Hewlett-Packard, and Lexmark drivers do not offer all
     of the additional options and improvements that the Epson driver
     does.  We do not have an estimated time for fix.  Please contact
     us if you would like to assist with this.

  3) Translation to other languages other than US-English is not
     supported in this release.  This will be fixed prior to 5.0 final
     release.

  4) Support for the Canon S200 has not yet been ported forward from
     4.2.

  5) This release is slower than 4.2 in many cases, particularly when
     using High Accuracy (which is the default color correction in
     most cases) or Bright color correction.  It is possible that this
     release will not be able to drive some printers at full speed,
     particularly if your computer has a slow processor.  Performance
     has been only partially analyzed or tuned at present.  We hope to
     improve the performance prior to final release.

  6) The user's manual and developer's guide have not been updated for
     this release.

  7) The CUPS PPD update script (cups-genppdupdate.5.0) will not
     update PPD files from 4.2 or from 4.3 prior to 4.3.21.  This is a
     permanent restriction.

  8) With certain versions of CUPS and in certain non-default
     configurations, if a new version of Gutenprint is installed over
     an existing version genppd will create PPD files based on the
     older version of Gutenprint or Gimp-Print rather than the newer
     version.  This will happen if all of the following are true:

     1) The cups-config provided by the CUPS driver adds
        -Wl,rpath=/usr/lib. This is done by some versions of CUPS
        reportedly because in some cases the runtime linker does not
        pick up libraries out of /usr/lib.  This can be checked by
        running

        cups-config --libs --ldflags

        and inspecting the output for any mention of "rpath", "RPATH",
        "RUN_PATH", or the like.  This is controlled by the CUPS
        installation on your system.

     2) There is presently a version of Gutenprint installed in /usr
        (--prefix=/usr) rather than /usr/local or the like.  The
        default location of Gutenprint installation is in /usr/local,
        but system vendors typically install Gutenprint in /usr.

     3) Gutenprint is built dynamically only (--disable-static).  This
        is not a default, and requires the explicit --disable-static
        on the Gutenprint "configure" command line.  Therefore, if you
        build Gutenprint normally you should not be vulnerable to this
        problem.

     Note that in general if you install CUPS into a non-standard
     location, and install Gutenprint into the same location, this
     problem can surface.  For example, if you choose to install CUPS
     in /usr/local and Gutenprint in /usr/local you are vulnerable to
     this.  However, it is not standard practice to install CUPS
     anywhere but /usr.

     In this case, the run path embedded in the genppd executable
     points to the version of Gutenprint installed in /usr/lib. This
     run path overrides any attempt by libtool to look in the build
     directory. The result is that cups-genppd and rastertogimpprint
     are run against the older version of Gutenprint. If the new
     version contains additional features (more printers, etc.) they
     will not be available.

     This bug is difficult to detect in a normal build.  It does not
     cause an error to happen during build; the only failure is that
     some PPD files may not be built or may be built with missing
     options.  Due to the PPD version checking introduced in this
     release, the behavior might manifest itself as a runtime error.
     It is also possible that there will be no error at all other than
     the older version of Gutenprint being used, with the result that
     new features and bug fixes are not available.

     If you wish to use only shared libraries, do not wish to build
     static libraries at all, and are vulnerable to this issue
     (because cups-config --ldflags sets the run path), there are
     three workarounds available:

     1) Build and install Gutenprint into /usr (rather than
        /usr/local) and then rebuild Gutenprint from scratch.  This
        will install the correct libgimpprint.so in /usr/lib, and in
        the rebuild genppd will be run against the correct library.

     2) Remove the old version of Gimp-Print or Gutenprint prior to
        building the new version of Gutenprint.  The important files
        to remove are anything named /usr/lib/libgimpprint*.

     3) Edit cups-config to remove the reference to the run path.

  9) There are multiple issues that one must be aware of when using
     Foomatic with Gutenprint.

     1) Before installing any new release of Gutenprint 5.0, you must
	manually remove any existing Foomatic option files.  This is
	because the Foomatic utility to load data kits
	(foomatic-kitload) does not remove obsolete data files from
	the Foomatic database.  If you do not do this, any PPD files
	you generate will be incorrect and printing may work
	incorrectly or not at all.

	Foomatic option files are usually located in 

	/usr/local/share/foomatic/db/source/opt

	or

	/usr/share/foomatic/db/source/opt

	Assuming they're in the former location, you must remove data
	files associated with the Gutenprint driver.  The command to do
	this, which must be run as the superuser (root) is

	cd /usr/local/share/foomatic/db/source/opt
	ls -l gutenprint-ijs*.xml

	If there are existing files present, you must remove them:

	rm -f gutenprint-ijs*.xml

	Now check to make sure that they are gone:

	ls -l gutenprint-ijs*.xml

	CAUTION: Be very careful when typing this command!  Minor
	errors in typing these commands may result in severe damage to
	your system.

	After this, you may run 'make install' in your Gutenprint
	source directory to install the package.  You will then need to
	re-create any printer queues using Foomatic.

	In general, you will have to perform this procedure any time
	you install a new version of Gutenprint.

	Please check the Foomatic site
	(http://www.linuxprinting.org/foomatic.html) and the Gutenprint
	site (http://gimp-print.sourceforge.net) for updated
	instructions about this.

     2) Unlike with the CUPS native driver, there is no simple way to
	update all PPD files when you install a new version of
	Gutenprint.  You must either use the foomatic-ppdfile command
	to upgrade PPD files individually, or foomatic-compiledb to
	build all PPD files.  Your system may provide an alternate way
	to install new PPD files, in which case you may use that
	method.

     3) From this point forward, the Foomatic data will be version
	locked to the Gutenprint release installed on the system.  For
	example, PPD files generated with the Foomatic data for this
	release will not work with the ijsgutenprint in the next
	release.  This is to prevent accidentally using incorrect
	data, which could cause incorrect function to take place.

  10) The fix for bug 929227 (Gimp-Print incorrectly attempts to build
     against GIMP 2.0) requires special build instructions if you are
     using a very old version of the GIMP 1.2 (versions affected are
     believed to include 1.2.0, 1.2.1, and 1.2.2).  Specifically, you
     must set GIMPTOOL in the environment to point to the proper
     version of gimptool when running Gutenprint's configure script.
     For example:

     GIMPTOOL=/usr/bin/gimptool ./configure

     The bug fix involves checking for the presence of the GIMP
     slightly differently from how it was previously done.
     Previously, Gimp-Print checked for the presence of a program
     named "gimptool", which provides information about how to build
     plugins against the GIMP.  This worked correctly when only the
     GIMP 1.2 was installed, but not when the GIMP 2.0 was installed.

     The GIMP 2.0 actually installs a program named "gimptool-2.0",
     and creates a symbolic link named "gimptool" pointing to it.
     Later versions of the GIMP 1.2 (1.2.3, 1.2.4, 1.2.5, and any
     later versions that may be released) similarly create a program
     named "gimptool-1.2" and a symbolic link named "gimptool".  As
     the configure script prior to this bug fix simply checked for
     gimptool, it incorrectly detected a gimptool from the GIMP 2.0.

     The current configure script checks first for gimptool-1.2 and
     then for gimptool, and only accepts the use of a GIMP 1.2 version
     of one of these programs.  However, if you have one of the older
     versions of the GIMP 1.2 installed in a non-standard location,
     and you use --with-gimp-prefix or --with-gimp-exec-prefix to
     specify its location, the configure script will not automatically
     detect the correct location of gimptool, and you must specify it
     as described above.  Note that you must specify a copy of
     gimptool from the GIMP 1.2, not from the GIMP 2.0.  If your copy
     of the GIMP is installed in a standard location (typically
     /usr/bin or /usr/local/bin), you do not need to use
     --with-gimp-prefix or --with-gimp-exec-prefix, and therefore do
     not need to use this workaround.

     If you cannot upgrade to the GIMP 2.x, the Gutenprint and GIMP
     projects recommend upgrading to revision of the GIMP 1.2.5, which
     will not require this workaround.  This workaround is available
     in the event that you cannot or do not wish to upgrade your
     installation of the GIMP.


* Architectural Changes:

  1) A modular architecture for family drivers.  A "family driver" is
     a collection of printer drivers for one group of printers sharing
     a common programming architecture, e. g. ESC/P2, PCL, Lexmark,
     Canon.

  2) A modular architecture for color processing.  This architecture
     will enable us, or others, to provide color management without
     having to change the internal interfaces within Gutenprint.

  3) New composite data types.  Gutenprint 5.0 defines additional data
     types.  These types include:

     * Sequences, curves, and arrays.  A sequence is a primitive
       vector of numbers data type; curves and arrays provide
       additional capabilities such as interpolation (for curves) and
       multiple dimensions (for arrays).

     * Lists are a general ordered container of named objects of
       arbitrary type.  They are used throughout the core library in a
       variety of ways.  The creator of a list can specify
       constructor, destructor, name comparison, copy, and sort
       operations on list members.

     * Parameters, which are part of the options system described
       below.  In addition to storing values and descriptions of the
       parameter, parameters can be queried to determine defaults and
       constraints.  Parameter lists (which use the list container
       internally) are also defined as part of this.

     * String lists are used in various ways; in particular, they are
       used by the parameter system to inform programs of the
       available choices of values for string-valued parameters.

  4) Complete overhaul of the options system.  Rather than offering a
     fixed set of operations, family drivers, color modules, etc. can
     now offer a wide variety of options using a predefined set of
     data types.  The data types currently supported are strings
     picked from a list, floating point numbers, integers, curves,
     arrays, Boolean values, dimensions, and filenames.

     The new options system provides a flexible way for drivers to
     inform applications of default values and UI hints, the ability
     to selectively enable and disable options, and a generalized way
     of verifying legality of option choices.

  5) The coordinate system has been changed from bottom left to top
     left of the page, and the printable area can now extend beyond
     the edge of the page.  The result is a more intuitive coordinate
     system for driver writers that matches the coordinate system of
     printers, and the ability to do true full bleed.

  6) The specification of color correction, input, and output modes
     has been completely revised, permitting applications to specify
     input mode, output mode, channel bit depth, and color correction
     completely independently.  This architecture is also more
     extensible.

  7) Complete overhaul of the black generation in CMYK output.  Black
     generation is now performed in the color code rather than the
     dither code.  This simplifies the dither code, puts the CMYK
     generation where it should be, and improves overall flexibility.

  8) Complete overhaul of the multi-tone (photo or quadtone) ink
     processing architecture (channels).  Instead of being processed
     as part of the dithering code as in 4.2, where ink drops of
     lighter inks were assigned virtual values proportional to their
     darkness as well as their size, this is now processed after the
     initial color conversion.  This has a number of major advantages:

     * As the actual amount of ink to be printed is visible to the
       color code, the color code can do ink limiting without fear
       that the dither code will change the amount of ink to be
       printed.

     * It ensures that the same proportions of inks will be printed at
       any density and resolution.  In 4.2, the ramp from light to
       dark ink varied depending upon the dot sizes available and
       hence the resolution.  This has already been demonstrated to
       yield much better linearity and much more neutral gray scale
       with even very modest tuning effort.

     * It enables use of all drop sizes of all ink tones.  In 4.2, we
       could not use the smallest drop size of dark ink, because the
       virtual dot size of a small dot of dark ink is typically close
       to the virtual dot size of a large dot of small ink.  This
       would yield very sharp transition, and perhaps even result in
       more light ink printed in darker regions than in lighter
       regions.  With channel processing separate from dithering, this
       concern no longer exists; we can safely use small drops of dark
       ink, improving smoothness.

     * It enables the color code to do ink limiting intelligently
       without concern that the dither code will rearrange things
       behind its back.

     * It greatly simplifies the specification of inks.  With drop
       size and darkness orthogonal, family drivers can greatly
       simplify their tables of inks.

     * Dither algorithms can choose to ignore smaller drop sizes if
       they wish to offer fast operation.

     * Applications with special requirements can now access the raw
       ink channels directly.  This facility was used to create a
       mechanism to more accurately tune printer inks.

  9) The color system can now generate arbitrary ink colors, lifting
     the CMYK-only restriction in previous versions of the package.
     This permits full support for the Epson Stylus Photo R800 and
     R1800, which use red and blue ink in addition to the traditional
     CMYK.

  10) Use of true XML to store data about printers and paper sizes, and
     to represent new data types (sequences, curves, and arrays).
     This uses the "mxml" XML library, a fast, lightweight XML parser
     written by Mike Sweet for this project.  Currently, the use of
     XML (as opposed to compiled-in data) is limited, but we expect
     that this will change beyond the initial 5.0 release.

  10) In addition to parameters, internal components such as family
     drivers, color drivers, etc. can store arbitrary data in the
     basic stp_vars_t object.  This facility is used to simplify the
     internal driver API; the family driver no longer needs to keep
     track of dither, color, etc. information itself.

  11) The Epson Stylus family driver has been decomposed into more
     functionally distinct units.  The data schema has been
     considerably improved, and the code itself broken into more
     easily maintained units.

  12) The build system has been updated with a more contemporary
     toolchain based on autoconf 2.5 and gettext 0.11.

  13) The Print plugin for the GIMP has been decomposed into a UI
     library and the core plugin.  The user interface library is a
     pure GTK-based library; the tiny GIMP plugin is a client of this
     library.

  14) Printer characteristics are exposed to the application level as
     read-only parameters.  This permits the escputil utility to not
     duplicate information stored in the printer driver.
================================================================


Supported Printers:

Many variations on these printers are also supported.  Generally, the
Epson printers are fully supported, although not fully tuned in all
cases; the Canon, HP, and Lexmark printers vary.

Our practice is to provide preliminary support for printers as soon as
we have information sufficient to code a functioning driver, and to
release this support even in an otherwise stable release.  In this
case, we note in the list below that support for a particular printer
is "Experimental".  It is likely that printers that are supported in
"Experimental" mode will produce poor quality at some or all
resolutions and in addition may not function correctly at some
resolutions.  Experimental Epson printers are most likely to produce
good output at the highest resolution offered (2880x720, 2880x1440, or
2880x2880 DPI), since in general these printers will not use multiple
drop sizes at such high resolutions.

Please see the printer-specific notes section following the list of
printers for any instructions specific to your printer.

================================================================

Printer-Specific Notes:

    * It is strongly recommended that four color mode not be used on
      the Epson Stylus C63, C64, C65, C66, C70, C80, C82, C83, C84,
      C85, C86, and CX-5200, and the PX-V500 and PX-V600 when printing
      to glossy papers, as the black ink is formulated differently
      from the color ink and does not adhere properly to these papers.
      Epson Photo Paper, Premium Glossy Photo Paper, Premium Luster
      Photo Paper, and Premium Semigloss Photo Paper are known to be
      affected.  If you use the Standard ink type, this will be
      handled automatically.

    * The Epson Stylus C70, C80, and C82 appear to support resolutions
      of 1440x1440 and 2880x1440, but these resolutions may not yield
      any improvement over 2880x720 or even 1440x720 DPI.  Due to
      improvements in the driver, these extremely high resolutions
      will offer very little if any improvement when printing
      photographs or other continuous-tone images.  For printing line
      art with extremely fine detail these resolutions may offer some
      improvement due to the nature of the printed image.  We expect
      that 1440x1440 would yield maximum improvement over 2880x720 on
      line art with very fine detail.  It is unlikely that 2880x1440
      would yield any significant additional improvement.

      Note that these resolutions are not officially supported by
      Epson on the C70 and C80, and may not work on all C70 and C80
      printers.

    * The Gutenprint Epson driver does not support the 5760 DPI
      resolutions (5760x720 or 5760x1440 DPI) offered by some Epson
      printers.  We do not believe that these resolutions offer any
      advantage over 2880x720 or 2880x1440 DPI, and indeed they may
      not offer any advantage over 1440x720 or 1440x1440 DPI.  No
      current Epson printer requires a resolution higher than
      2880x2880 DPI to fill the page with the smallest drop size used,
      and the effective resolution is generally determined by the
      lower of the horizontal and vertical resolution.  Raising the
      horizontal resolution without a corresponding increase in the
      vertical resolution merely requires more computation and
      printing time without yielding significantly better quality.

      In some cases, we offer resolutions different from what Epson
      advertises that have the same effect; for example, we offer
      2880x2880 DPI on the Epson Stylus C86 rather than the 5760x1440
      offered by Epson's native driver.

      We do not currently plan to offer resolutions higher than
      2880x2880 DPI on any Epson Stylus printer with a drop size of 1
      pl or larger.  At the time of Gutenprint 5.0 release, the
      smallest drop size offered by any Epson Stylus printer is 1.5
      pl.  If such a printer is offered, or we otherwise determine
      that there are advantages to be had from offering such
      resolutions, we will evaluate whether to offer higher
      resolutions.

    * Many Epson printers (specifically, the Epson Stylus Color 740
      and all newer printers) will not respond to ASCII text without a
      special "activation" sequence (specifically, this command takes
      the printers out of "packet mode").  A brand new printer, or one
      that has been connected to a Windows system, may or may not work
      in packet mode.  Therefore, the common suggestion to test a
      printer port by sending plain text to it may not work for these
      printers; failure to print in this fashion is not a positive
      indication that the printer or the connection is malfunctioning.
      These printers are, however, able to print plain text *after*
      the activation sequence is sent.

      A suggestion would be to first verify that the printer is
      capable of returning ink levels.  This may be done via

      escputil -i -r /dev/lp0

      (or whatever device your printer is connected to in place of
      /dev/lp0).  If this returns status, it demonstrates that the
      link between your computer and printer is working.
