Welcome to Gutenprint 5.2.1! Please read these notes carefully. *** NOTE TO PACKAGERS: Please read the file README.package for issues that are of interest to distributors and packagers of Gutenprint. It is not necessary for end users of Gutenprint to read this file. ================================================================ I) INTRODUCTION This is Gutenprint version 5.2.1, the first release of Gutenprint 5.2. 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 10.3 and newer) and Linux systems in many cases equal to or better than proprietary vendor-supplied drivers. Gutenprint also includes an enhanced print plug-in for the GIMP image editor, replacing the Gimp-Print 4.2-based plugin supplied with GIMP 1.2, 2.0, and 2.2, and offering an alternative with additional capabilities to the GtkPrint-based plugin supplied with GIMP 2.4 and beyond. Gutenprint has been renamed in order to clearly distinguish it from GIMP. While this package started out as the Print plugin for GIMP, it has expanded into a collection of general purpose printer drivers, and the enhanced Print plugin for GIMP is now only a small part 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. Please read the user's manual (in ODF format as doc/gutenprint-users-manual.odt or PDF format as doc/gutenprint-users-manual.pdf) carefully, as it covers much more information than this README file. The user's manual contains a complete list of supported printers. In addition, please read the release notes (NEWS), as it has information on the latest changes. This package has changed significantly since Gutenprint 5.0. Gutenprint supports only the printer part of multi-function devices (devices that typically include scanning, copying, and fax capabilities). We recommend that all users who wish to use this package for general purpose printing use either CUPS or, if they use another printing system or no spooler at all, use Foomatic with the Ghostscript driver (both described below), rather than integrating the Ghostscript driver with self-made scripts or even manually typing in Ghostscript command lines. It is much simpler to manage with CUPS or Foomatic and its PPDs. CUPS provides an excellent web-based interface for easy printer administration, and all CUPS-enabled applications (OpenOffice.org, all KDE apps, etc.) and printing dialogs (kprinter, xpp, etc.) show all the options in easy to use GUIs. Please visit http://www.cups.org/ for information on downloading and installing CUPS. ================================================================ II) INSTALLATION This section is provided for people installing the package from source. If you are installing from a pre-compiled package (such as the Macintosh OS X package, or a package provided by your distribution vendor), you may skip this section. Installing packages from source requires some level of system administration skills along with superuser privileges. Superuser privilege allows you to perform actions that may be damaging to your system. If you are not comfortable with the material discussed here and in the release notes, or with performing simple administrative actions, we recommend that you not attempt to install this package from source. Before beginning, please read the release notes carefully for any updates. ---------------- A) OVERVIEW Gutenprint includes the following primary components: - The core driver library (required for everything else) - A CUPS (Common UNIX Printing System) driver - An enhanced Print plug-in for GIMP - GTK-based UI libraries (used by the enhanced GIMP plug-in) - Support for the Foomatic spooler configuration system - A Ghostscript driver using the IJS plugin facility - A command-line utility to administer and maintain Epson printers This package requires the use of GNU Make to compile. On systems with both GNU make and another make installed, GNU make may be named `gmake' or `gnumake'. BSD users in particular must take care to use 'gmake'. The general procedure to build Gutenprint is as follows: ./configure [options] make make install The "configure" script, which must be run before doing anything else, controls which of these components are built along with any options desired. This script determines what software is installed on your system and what components will be compatible with it, and prepares the package to be built and installed. If the script emits any warnings or errors, please be certain that you understand them before proceeding. After the configure script has completed its work, it will print a summary of its choices. Please ensure that it is correct before proceeding. The summary looks like this: Configuration Summary: ------------- -------- If you have any problems, please report the information below to gimp-print-devel@lists.sourceforge.net ================================================================ Release: gutenprint 5.2.1 generated on 18 Oct 2008 Features: Build CUPS: yes, installing in /usr Build CUPS 1.2 enhancements: yes Build CUPS PPD files: no Generate PS level 3 CUPS PPD files: yes Build genppd statically: yes Build Ghostscript IJS driver: yes Build Foomatic data: yes Build Foomatic 3.x data: yes Build enhanced Print plugin for GIMP: yes GIMP plugin will be named: gutenprint Install plugin(s) in home directory: no Build EPSON Stylus utility: yes Build test programs: yes Build testpattern generator: yes Installation summary: Installation prefix: /usr/local Data directory: /usr/local/share/gutenprint Library directory: /usr/local/lib/gutenprint XML data directory: /usr/local/share/gutenprint/5.2/xml Module directory: /usr/local/lib/gutenprint/5.2/modules Install sample images: yes General configuration: Compiler options: -Disfinite=finite -O6 -Wall -Wcast-align -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Wwrite-strings -Werror-implicit-function-declaration -Winline -Wformat=2 -finline-limit=131072 -pedantic -Waggregate-return -Wcast-qual -Wshadow -Wredundant-decls Build static libraries: yes Build shared libraries: no Maintainer mode: yes Use i18n: yes Generate profiling information: no Generate debugging symbols: no Use modules: static Use readline libraries: yes, extra arguments: -lncurses uname -a output: Linux linuxhome 2.6.25.11-0.1-default #1 SMP 2008-07-13 20:48:28 +0200 x86_64 x86_64 x86_64 GNU/Linux ================================================================ The CUPS, GIMP, Foomatic, and Ghostscript components require that the appropriate packages be installed on your system. Many distribution vendors separate packages into runtime and development packages. The development packages are required in order to successfully compile Gutenprint. In many cases the configure script cannot detect whether these development packages are installed, in which case you will get an error during compilation. Also note that it is necessary for the versions of the development packages to match exactly the versions of the runtime packages they are related to. ---------------- B) CORE DRIVER LIBRARY The core driver library, which is always built, contains all of the printer drivers comprising the Gutenprint package. When the package is built, it consists of a core library (libgutenprint), a set of XML files, and depending upon the options selected, additional libraries containing the drivers for each family of printers. By default dynamically loadable modules (plug-ins) will be built for the family drivers, and loaded at run-time if your operating system supports it. If you experience problems, --with-modules=dlopen or --with-modules=ltdl may be used to select the module loading method (dlopen is the default, but GNU libltdl is more portable), or --with-modules=static or --without-modules disables them. If you wish to compile Gutenprint entirely statically (with no use of shared libraries), you may use the option --disable-shared. ---------------- C) CUPS Gutenprint may be used as a driver under CUPS (Common UNIX Printing System), if your system uses that spooler. Full description of CUPS is beyond the scope of this README file; full information may be found at http://www.cups.org. Gutenprint 5.2 requires CUPS 1.1.9 or higher. We recommend use of 1.1.15 or above; that release of CUPS fixes some important bugs. Gutenprint supports CUPS 1.2, and supports the CUPS 1.2 enhancements, including dynamic PPD file generation. Gutenprint will normally detect the presence of CUPS on your system and will attempt to build the CUPS driver if it finds CUPS installed. If your distribution separates the CUPS installation into development and runtime packages, you must install the CUPS development package (cups-devel or similar). You may need to install other development packages depending upon how your distribution has built CUPS. The list of packages varies, but commonly development packages for TIFF (libtiff-devel), JPEG (jpeg-devel or libjpeg-devel), PNG (libpng-devel) and OpenSSL (openssl-devel) will be required. Failure to install these packages will lead to errors when the package is compiled. Installing the CUPS driver for Gutenprint 5.2 will not interfere with your ability to continue using the Gutenprint 5.0 or Gimp-Print 4.2 CUPS driver. WARNING: The "canon" and "epson" CUPS backends that previously were distributed with Gutenprint are no longer distributed, so you will need to ensure that none of your printer queues use these backends. Please read the Critical Upgrade Note in the release notes for more information and the procedure for modifying your printer queues. The Gutenprint CUPS driver consists of the following components: * The core Gutenprint CUPS driver, rastertogutenprint.5.2. This is a CUPS filter that converts CUPS raster data into printer-specific data. This is most commonly installed in /usr/lib/cups/filter. * Additional utilities to send certain commands to these printers are installed as commandtocanon and commandtoepson; they are installed in /usr/lib/cups/filter. * One or more sets of PPD files describing all of the printers supported by Gutenprint. These are normally installed in /usr/share/cups/model/gutenprint. These PPD files can only be used by the precise version of Gutenprint that they were built with; for example, it is not possible to use PPD files from Gutenprint 5.0.0 with Gutenprint 5.2.0. If you are using CUPS 1.2 or above, these PPD files are not actually installed by default. Instead, a CUPS driver generates these PPD files on demand. * A utility to update PPD files from an earlier release of Gutenprint, cups-genppdupdate. This utility may be used to update PPD files generated by earlier versions of Gutenprint starting from 4.3.21, including any 5.0, 5.1, or 5.2 release or pre-release. This is normally installed in /usr/sbin. This utility cannot update PPD files from Gimp-Print 4.2. * A utility to generate PPD files, cups-genppd.5.2. Normally this is only required when the package is built, and only with CUPS 1.1. * A driver to generate PPD files on the fly, gutenprint.5.2. This is normally used to generate PPD files on the fly with CUPS 1.2 and above. * A utility to permit additional color calibration for Gutenprint-supported printers, cups-calibrate. This is normally installed in /usr/bin. WARNING: With certain versions of CUPS and in certain non-standard 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 rather than the newer version. This will happen if all of the following are true: i) The cups-config provided by the CUPS driver adds -Wl,rpath=/usr/lib (or wherever the CUPS system libraries live). 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. ii) There is presently a version of Gutenprint installed in the system default, typically /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. iii) Gutenprint is built dynamically only (--disable-static or --disable-static-genppd). This is not standard, and requires the explicit --disable-static or --disable-static-genppd on the Gutenprint "configure" command line. Therefore, if you build Gutenprint normally you should not be vulnerable to this problem. iv) Gutenprint is configured to build the PPD files at compile time. This is the case when using CUPS 1.1, but is not the case when using CUPS 1.2 unless you explicitly use --enable-cups-ppds. 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 rastertogutenprint are run against the older version of Gutenprint. If the new version contains additional features (more printers, changes to printer options, etc.) they will not be available. This bug is difficult to detect in a normal build. It normally does not cause an error to happen during build unless there is an API change from the version installed and the version being built; the only failure is frequently 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: i) Build and install Gutenprint into /usr (rather than /usr/local) and then rebuild Gutenprint from scratch. This will install the correct libgutenprint.so in /usr/lib, and in the rebuild genppd will be run against the correct library. ii) Remove the old version of Gutenprint prior to building the new version of Gutenprint. The important files to remove are anything named /usr/lib/libgutenprint*. iii) Edit cups-config to remove the reference to the run path. Following installation of the package with "make install", you must restart CUPS to permit CUPS to see the new PPD files. The exact command to restart CUPS varies; it is typically something like /etc/init.d/cups restart, /etc/software/init.d/cups restart, /etc/rc.d/cups restart, /usr/sbin/rccups, or even /etc/rc.d/init.d/cups restart. Your system may have a different way to restart the CUPS server. OS X (10.3, 10.4, and 10.5), for example, uses the following command: sudo /System/Library/StartupItems/PrintingServices/PrintingServices.sh restart You may optionally choose to update your existing PPD files using the command cups-genppdupdate, after which you should restart CUPS as described above. We strongly recommend use of this update procedure, which is fast and simple. This script will automatically update Gutenprint PPD files from earlier versions (5.0, 5.1, or 5.2 release or prerelease). This script will only update PPD files from earlier versions of Gutenprint; it will not update Gimp-Print 4.2 PPD files or PPD files from other drivers. However, you may install Gutenprint 5.2 alongside Gimp-Print 4.2, and use both Gimp-Print 4.2 and Gutenprint 5.2 drivers concurrently in separate printer queues. Therefore, you need not convert a workflow based on Gimp-Print 4.2 right away, but can gradually convert or even permanently use both drivers for different printer queues. The following options to configure are available for compiling the Gutenprint driver for CUPS: --enable-cups-ppds With CUPS 1.2, it is possible to arrange for PPD files to be generated when a new printer queue is generated rather than having all pre-generated PPD files in the filesystem. This saves considerable disk space and avoids the possible build problem described above. Normally, Gutenprint detects which version of CUPS is in use and configures itself to create the PPD files at build time only when CUPS 1.1 is in use. If you wish to generate the PPD files at build time, you may use this option. If you are running CUPS 1.1, and for some reason do not wish to generate the PPD files, you may use --disable-cups-ppds. --disable-translated-cups-ppds By default, PPD files for all languages available in Gutenprint are created. If this option is used, only the default (US-English) PPD files are created. Distributors may wish to package up the PPD files separately for each language. Some systems may not build the translated PPD files correctly, in which case all of the PPD files will be in English. If this is the case on your system, you should use --disable-translated-cups-ppds to avoid having many duplicate PPD files. --disable-globalized-cups-ppds Starting with Gutenprint 5.2, Gutenprint builds PPD files containing translations for all languages if CUPS 1.2 or above is in use. This greatly reduces the number of PPD files created or PPD file choices offered. If you have problems with the globalized PPD files, you may use this option to generate standard translated PPD files (or English-only, if --disable-translated-cups-ppds is also in use). This option only has effect if --enable-cups-ppds is used. --enable-simplified-cups-ppds Gutenprint 5.2 offers an option of creating simplified PPD files (containing only basic options and standard paper sizes) in addition to PPD files offering all available options (including all color correction options). If this option is used, both the simplified and standard PPD files are created. If --enable-simplified-cups-ppds=only is specified, only the simplified PPD files are built. If the new dynamic PPD file generation is used with CUPS 1.2, the simplified PPD files are always offered. --disable-cups-level3-ppds By default, the Gutenprint PPD files are configured for PostScript Level 3. If this option is used, Level 2 PPD files are created. This may be useful if you are using a version of CUPS older than 1.1.15. It is normally not necessary to use this explicitly, as the configure script detects the version of CUPS in use and selects the appropriate PostScript level automatically. --disable-cups-ppds-at-top-level Normally, the PPD files are placed in /usr/share/cups/model/gutenprint/5.2. If this option is used, the PPD files are placed in /usr/share/cups/model. There is normally no good reason to use this option. --disable-static-genppd Build genppd and rastertogutenprint dynamically linked rather than statically linked. WARNING: Use of this option may lead to failure during build or installation, or incorrect installation. It is *STRONGLY* recommended that you not use this option unless you are certain that you understand the problem and how to work around it. ---------------- D) FOOMATIC Foomatic is a printer meta-driver that can be used with any spooler (CUPS, lpd, LPRng, etc.) or even no spooler at all. It uses XML data describing printer and driver capabilities in conjunction with Ghostscript to allow printing in any environment. Please visit http://www.openprinting.org/foomatic.html for more information. We normally recommend using the native CUPS driver described above if your system uses CUPS as its spooler. However, some systems (many releases of Fedora Core, for example) use Foomatic as the repository for all printer information; the tools provided on those systems will not recognize the CUPS PPD files. If your system uses Foomatic in this way, or does not use CUPS, you should use Foomatic to manage your printers. If you are using CUPS, however, we strongly recommend using the CUPS driver described in the previous section in preference to Foomatic. The Gutenprint driver for Foomatic requires Foomatic 2.0 or higher; Foomatic 3.0 or above is highly recommended. It also requires GNU Ghostscript 6.53 or newer, AFPL Ghostscript 7.04 or newer, or ESP Ghostscript 7.05 or newer for IJS support. We recommend Ghostscript 8 or above. The Foomatic support in Gutenprint consists of a data generator and an IJS-based Ghostscript driver. It is possible to use the Ghostscript driver without Foomatic, but the Gutenprint options are complex and subject to change without notice. Older printer configuration tools such as apsfilter and magicfilter do not provide a convenient interface to the driver's capabilities. Therefore, we no longer provide documentation on direct use of the Ghostscript driver without the Foomatic front end. The Ghostscript driver in Gutenprint 5.2 is based on the IJS protocol. IJS is a protocol originally developed by Hewlett-Packard to allow new drivers to be used with Ghostscript without having to be compiled into Ghostscript. Gutenprint 5.2 offers two Foomatic drivers, one supporting the full range of options and the other supporting simplified options, as describe above under CUPS. The full-featured driver is named "gutenprint-ijs.5.2"; the simplified driver is named "gutenprint-ijs-simplified.5.2". Gutenprint 5.2 may coexist with Gimp-Print 4.2; both drivers may be installed and used (on separate printer queues, of course) on the same system. Normally, the Gutenprint configure script will automatically detect the presence of Foomatic and Ghostscript on your system. In some cases, you may have to install a Ghostscript development package that may be named gs-devel, ghostscript-library, or the like for the IJS capability. The Foomatic driver will not allow use of PPD files created from Foomatic data from a different version of Gutenprint. This ensures that the PPD files accurately match the driver in use. However, there is no automatic upgrade tool provided for the Foomatic driver, unlike the CUPS driver. Therefore, all queues using a Gutenprint driver must be updated manually, using either tools provided by your distribution or the Foomatic tool "foomatic-ppdfile". NOTES TO PACKAGERS: * We recommend packaging the IJS driver (/usr/bin/ijsgutenprint.5.2) and its man page (/usr/man/man1/ijsgutenprint.1.gz) together with the Foomatic data. * The IJS driver and the Foomatic data kit and PPD files are versioned, and hence you should consider permitting multiple versions to be installed concurrently. The man page (/usr/man/man1/ijsgutenprint.1.gz) is not versioned. ---------------- E) GIMP Gutenprint may be used as an enhanced Print plug-in for GIMP (2.0 and above), providing the ability to print images. Please read the release notes in addition to this README. Gutenprint 5.2 no longer supports GIMP 1.2. The enhanced Print plugin for GIMP replaces the Gimp-Print 4.2-based plugin provided with GIMP 2.0 and 2.2. As of the GIMP 2.4, GIMP team provides a new Print plugin based on the GtkPrint framework. This plugin provides standard printing capabilities, but does not provide all of the new Gutenprint 5.2 features. Therefore, the enhanced Print plugin for GIMP distributed with Gutenprint does not replace that plugin, but is installed alongside that plugin. If your system separates development packages from runtime packages, you will typically have to install development packages for GIMP itself, in addition to Gtk and Glib. With GIMP 2.x and GTK 2.x, additional packages may be required. Normally, the Gutenprint configure script detects which version, if any, of GIMP is installed and builds an appropriate plugin. If the configure script does not detect it properly, you may need to specify --with-gimp or --with-gimp2. However, it's more likely that you need to install appropriate development packages. Normally Gutenprint installs GIMP Print plugin in your system plug-in directory. If you wish to install it in your personal plugin directory, you may use ./configure --enable-user-install It is not possible for Gimp-Print 4.2, Gutenprint 5.0, and Gutenprint 5.2 (or any future release) to coexist in the same installation of GIMP. The Gutenprint 5.2-based plugin can read settings from previous versions of Gimp-Print, but the configuration file format in Gutenprint 5.2 cannot be read by older versions of Gimp-Print or Gutenprint. ---------------- F) ESCPUTIL "escputil" is a command line utility for administering Epson inkjet printers. It performs head alignment, retrieval of ink levels and status information, printing of test patterns, etc. It is built and installed by default; if you don't want it, you may use --without-escputil when configuring. escputil uses the readline package for interactive commands (currently only head alignment falls into this category). Linking against libreadline sometimes requires linking against other packages. Gutenprint attempts to determine the correct packages to link against; the exact sequence is described in the release notes. If you do not wish to use readline, you may use --without-readline. ================================================================ III) GETTING STARTED This section describes how to get started by installing printers under Gutenprint. Please see the user's manual (in doc/gutenprint-users-manual.odt or doc/gutenprint-users-manual.pdf) for more information. ---------------- A) PRINTER INSTALLATION The actual procedure to install a printer depends upon your operating system and the spooler (printing system) in use on your system. Gutenprint does not normally require the use of non-standard procedures (such as starting special programs) to install printers. Assuming that you are using either CUPS or Foomatic, it integrates with your printing system, so the tools provided by your distribution vendor should work correctly with Gutenprint. Most printing systems currently use PPD files to describe printer capabilities. Some printers are supported by more than one driver, so you may find more than one PPD file for your printer. Gutenprint PPD files are described as Epson Stylus Photo R300 - CUPS+Gutenprint v5.2.0 Epson Stylus Photo R300 - CUPS+Gutenprint v5.2.0 Simplified Epson Stylus Photo R300 Foomatic/gutenprint-ijs.5.2 Epson Stylus Photo R300 Foomatic/gutenprint-ijs-simplified.5.2 The "simplified" PPD files offer a basic set of options only, for selecting printer options, standard paper sizes, and basic quality settings. The PPD files that are not "simplified" offer a much broader set of controls, giving the user extensive control over quality and color adjustment. If you are using CUPS, you may be offered a choice between CUPS+Gutenprint and Foomatic/gutenprint-ijs PPD files. While either kind of PPD file will work, we recommend using the CUPS+Gutenprint PPD files. These PPD files can be automatically updated with cups-genppdupdate when you later upgrade your Gutenprint installation. Some systems mark the Foomatic PPD files as "(recommended)"; we nevertheless recommend using the CUPS+Gutenprint PPD files. Other PPD files are described differently, such as Epson MJ 520C Foomatic/stcolor (recommended) These PPD files, whether "recommended" or not, are not Gutenprint PPD files. NOTES FOR CUPS USERS: If you do not choose to automatically update existing PPD files, you should reinstall any printer queues that you are using Gutenprint PPD files with. The Gutenprint driver and the PPD files must be kept in sync, since the PPD files reflect the particular version of the driver that they were built against. If you attempt to use a version of Gutenprint with PPD files not built for that precise version, the driver will fail with a diagnostic error message. For example, PPD files built for Gutenprint 5.2.0-beta4 will not work with driver version 5.2.1. You can identify printers using Gutenprint PPD files by the name of the PPD file, which will be something like: EPSON Stylus Photo EX - CUPS+Gutenprint v5.2.1(en) Linux users please note: If you are using CUPS 1.1.11 or higher, and you have a USB-connected printer, you must have a printer connected to each USB port that you plan to use and powered on when you restart CUPS. If you do not do so, you will not be able to reinstall the printer. It is only necessary to do this if you wish to update PPD files manually; if you use cups-genppdupdate, you do not need to do this. Starting with CUPS 1.1.11, you cannot choose an AppSocket connection and enter "usb:/dev/usblp0" or the like as the URI; you will get a "client-error-not-possible" error at the end of the installation process, and you will have a message like the following in your CUPS error log (typically /var/log/cups/error_log): E [21/Nov/2001:17:59:07 +0500] add_printer: bad device-uri attribute 'usb:/dev/usb/lp0'! If the printer was turned on correctly, you will be given a choice of a USB connection in the Device dialog. You may also have problems if you have a .lpoptions file that has old options set. If you have problems printing, please remove any existing .lpoptions file in your home directory and try printing again. ================================================================ IV) SOLVING PROBLEMS While we have attempted to make use of Gutenprint as straightforward and trouble-free as possible, we certainly recognize that there may be problems with installing and using Gutenprint. In the event of any difficulty, we ask that you take the following actions: 1) Read the release notes (NEWS). 2) Read the FAQ, in doc/FAQ.html. Your question may be answered there. 3) Make sure that the paper type and size, and media source, that you have selected matches the paper loaded into the printer. This is only necessary if the printer attempts to print, but does not succeed. It is a good starting point if quality is poor (too dark or too light, wet ink on the paper, etc.). 4) Reset all settings (particularly the color and quality settings) to their defaults. 5) If you are using CUPS, search /var/log/cups/error_log (which may be located elsewhere on some systems) for lines starting with 'E' (these lines indicate errors). Also search for log information produced by Gutenprint; all such output lines will contain "Gutenprint". These lines may help you solve the problem and will help us investigate your problem if necessary. 6) If you are using CUPS, enable debugging output. This can be done by editing /etc/cups/cupsd.conf (which must be done as root). There will be a line in that file: LogLevel Info which should be changed to LogLevel Debug This will allow CUPS to produce extensive debugging output. You will need to restart CUPS (the exact procedure is system-dependent) after doing this. If you report a problem to the Gutenprint team, you will be asked for this information. 7) There are public forums on Sourceforge dedicated to this package. Please see http://sourceforge.net/forum/?group_id=1537 for more information. The Help forum is a good source of information. 8) If you have a technical support issue that does not appear to be a bug in the software, you can use the Tech Support Manager. Please see http://sourceforge.net/support/?group_id=1537. 9) If you have found a clear bug in the package, you may file a bug report at http://sourceforge.net/bugs/?group_id=1537. 10) You may send mail to the gimp-print-devel@sourceforge.net mailing list. This is recommended as a last resort only. ================================================================ V) USE OF THE CVS REPOSITORY Please read doc/README.maintaining for instructions on how to build from the CVS repository. You will need additional packages and tools for this purpose.
