+INSTALL - CUPS v2.2.4 - 2017-05-01
+==================================
+
+This file describes how to compile and install CUPS from source code. For more
+information on CUPS see the file called "README.txt".  A complete change log can
+be found in "CHANGES.txt".
+
+> USING CUPS REQUIRES ADDITIONAL THIRD-PARTY SUPPORT SOFTWARE AND PRINTER
+> DRIVERS.  THESE ARE TYPICALLY INCLUDED WITH YOUR OPERATING SYSTEM
+> DISTRIBUTION.  APPLE DOES NOT ENDORSE OR SUPPORT THIRD-PARTY SUPPORT SOFTWARE
+> FOR CUPS.
+
+
+BEFORE YOU BEGIN
+----------------
+
+You'll need ANSI-compliant C and C++ compilers, plus a make program and POSIX-
+compliant shell (/bin/sh).  The GNU compiler tools and Bash work well and we
+have tested the current CUPS code against several versions of GCC with excellent
+results.
+
+The makefiles used by the project should work with most versions of make.  We've
+tested them with GNU make as well as the make programs shipped by Compaq, HP,
+SGI, and Sun.  BSD users should use GNU make (gmake) since BSD make does not
+support "include".
+
+Besides these tools you'll want ZLIB library for compression support, the GNU
+TLS library for encryption support on platforms other than iOS, macOS, or
+Windows, and either MIT (1.6.3 or higher) or Heimdal Kerberos for Kerberos
+support.  CUPS will compile and run without these, however you'll miss out on
+many of the features provided by CUPS.
+
+Also, please note that CUPS does not include print filters to support PDF or
+raster printing.  You *must* download GPL Ghostscript and/or the Open Printing
+CUPS filters package separately to print on operating systems other than macOS.
+
+
+CONFIGURATION
+-------------
+
+CUPS uses GNU autoconf, so you should find the usual "configure" script in the
+main CUPS source directory.  To configure CUPS for your system, type:
+
+    ./configure
+
+The default installation will put the CUPS software in the "/etc", "/usr", and
+"/var" directories on your system, which will overwrite any existing printing
+commands on your system.  Use the "--prefix" option to install the CUPS software
+in another location:
+
+    ./configure --prefix=/some/directory
+
+To see a complete list of configuration options, use the --help option:
+
+    ./configure --help
+
+If any of the dependent libraries are not installed in a system default location
+(typically "/usr/include" and "/usr/lib") you'll need to set the CFLAGS,
+CPPFLAGS, CXXFLAGS, DSOFLAGS, and LDFLAGS environment variables prior to running
+configure:
+
+    setenv CFLAGS "-I/some/directory"
+    setenv CPPFLAGS "-I/some/directory"
+    setenv CXXFLAGS "-I/some/directory"
+    setenv DSOFLAGS "-L/some/directory"
+    setenv LDFLAGS "-L/some/directory"
+    ./configure ...
+
+or:
+
+    CFLAGS="-I/some/directory" \
+    CPPFLAGS="-I/some/directory" \
+    CXXFLAGS="-I/some/directory" \
+    DSOFLAGS="-L/some/directory" \
+    LDFLAGS="-L/some/directory" \
+    ./configure ...
+
+The "--enable-debug" option compiles CUPS with debugging information enabled.
+Additional debug logging support can be enabled using the
+"--enable-debug-printfs" option - these debug messages are enabled using the
+CUPS_DEBUG_LOG environment variable at run-time.
+
+CUPS also includes an extensive set of unit tests that can be used to find and
+diagnose a variety of common problems - use the "--enable-unit-tests" configure
+option to run them at build time.
+
+On macOS, use the "--with-archflags" option to build with the correct set of
+architectures:
+
+    ./configure --with-archflags="-arch i386 -arch x86_64" ...
+
+> Note: Current versions of macOS DO NOT allow installation to /usr with the
+> default system integrity settings.  In addition, we do not recommend replacing
+> the CUPS supplied with macOS because not all versions of CUPS are compatible
+> with every macOS release, and because software updates will replace parts
+> of your local installation potentially rendering your system unusable.
+
+Once you have configured things, just type:
+
+    make ENTER
+
+or if you have FreeBSD, NetBSD, or OpenBSD type:
+
+    gmake ENTER
+
+to build the software.
+
+
+TESTING THE SOFTWARE
+--------------------
+
+Aside from the built-in unit tests, CUPS includes an automated test framework
+for testing the entire printing system.  To run the tests, just type:
+
+    make check ENTER
+
+or if you have FreeBSD, NetBSD, or OpenBSD type:
+
+    gmake check ENTER
+
+The test framework runs a copy of the CUPS scheduler (cupsd) on port 8631 in
+/tmp/cups-$USER and produces a nice HTML report of the results.
+
+
+INSTALLING THE SOFTWARE
+-----------------------
+
+Once you have built the software you need to install it.  The "install" target
+provides a quick way to install the software on your local system:
+
+    make install ENTER
+
+or for FreeBSD, NetBSD, or OpenBSD:
+
+    gmake install ENTER
+
+Use the BUILDROOT variable to install to an alternate root directory:
+
+    make BUILDROOT=/some/other/root/directory install ENTER
+
+You can also build binary packages that can be installed on other machines using
+the RPM spec file ("packaging/cups.spec") or EPM list file
+("packaging/cups.list").  The latter also supports building of binary RPMs, so
+it may be more convenient to use.
+
+You can find the RPM software at:
+
+    http://www.rpm.org/
+
+The EPM software is available at:
+
+    https://michaelrsweet.github.io/epm
+
+
+CREATING BINARY DISTRIBUTIONS WITH EPM
+--------------------------------------
+
+The top level makefile supports generation of many types of binary distributions
+using EPM.  To build a binary distribution type:
+
+    make <format> ENTER
+
+or
+
+    gmake <format> ENTER
+
+for FreeBSD, NetBSD, and OpenBSD.  The <format> target is one of the following:
+
+- "epm": Builds a script + tarfile package
+- "bsd": Builds a *BSD package
+- "deb": Builds a Debian package
+- "pkg": Builds a Solaris package
+- "rpm": Builds a RPM package
+- "slackware": Build a Slackware package
+
+
+GETTING DEBUG LOGGING FROM CUPS
+-------------------------------
+
+When configured with the "--enable-debug-printfs" option, CUPS compiles in
+additional debug logging support in the scheduler, CUPS API, and CUPS Imaging
+API.  The following environment variables are used to enable and control debug
+logging:
+
+- `CUPS_DEBUG_FILTER`: Specifies a POSIX regular expression to control which
+  messages are logged.
+- `CUPS_DEBUG_LEVEL`: Specifies a number from 0 to 9 to control the verbosity of
+  the logging. The default level is 1.
+- `CUPS_DEBUG_LOG`: Specifies a log file to use.  Specify the name "-" to send
+  the messages to stderr.  Prefix a filename with "+" to append to an existing
+  file.
+
+
+REPORTING PROBLEMS
+------------------
+
+If you have problems, READ THE DOCUMENTATION FIRST!  If the documentation does
+not solve your problems, please post a message on the users forum at:
+
+    https://www.cups.org/
+
+Include your operating system and version, compiler and version, and any errors
+or problems you've run into.  The "config.log" file and the output from the
+configure script and make should also be sent, as it often helps to determine
+the cause of your problem.
+
+If you are running a version of Linux, be sure to provide the Linux distribution
+you have, too.

-*******************************************************************************
-*******************************************************************************
-
-
-BEFORE YOU BEGIN
-
-    You'll need ANSI-compliant C and C++ compilers, plus a make program and
-    POSIX-compliant shell (/bin/sh).  The GNU compiler tools and Bash work well
-    and we have tested the current CUPS code against several versions of GCC
-    with excellent results.
-
-    The makefiles used by the project should work with most versions of make.
-    We've tested them with GNU make as well as the make programs shipped by
-    Compaq, HP, SGI, and Sun.  BSD users should use GNU make (gmake) since BSD
-    make does not support "include".
-
-    Besides these tools you'll want ZLIB library for compression support, the
-    GNU TLS library for encryption support on platforms other than iOS, macOS,
-    or Windows, and either MIT (1.6.3 or higher) or Heimdal Kerberos for
-    Kerberos support.  CUPS will compile and run without these, however you'll
-    miss out on many of the features provided by CUPS.
-
-    Also, please note that CUPS does not include print filters to support PDF
-    or raster printing.  You *must* download GPL Ghostscript and/or the Open
-    Printing CUPS filters package separately to print on operating systems
-    other than macOS.
-
-
-CONFIGURATION
-
-    CUPS uses GNU autoconf, so you should find the usual "configure" script in
-    the main CUPS source directory.  To configure CUPS for your system, type:
-
-	./configure
-
-    The default installation will put the CUPS software in the "/etc", "/usr",
-    and "/var" directories on your system, which will overwrite any existing
-    printing commands on your system.  Use the "--prefix" option to install the
-    CUPS software in another location:
-
-	./configure --prefix=/some/directory
-
-    To see a complete list of configuration options, use the --help option:
-
-        ./configure --help
-
-    If any of the dependent libraries are not installed in a system default
-    location (typically "/usr/include" and "/usr/lib") you'll need to set the
-    CFLAGS, CPPFLAGS, CXXFLAGS, DSOFLAGS, and LDFLAGS environment variables
-    prior to running configure:
-
-	setenv CFLAGS "-I/some/directory"
-	setenv CPPFLAGS "-I/some/directory"
-	setenv CXXFLAGS "-I/some/directory"
-	setenv DSOFLAGS "-L/some/directory"
-	setenv LDFLAGS "-L/some/directory"
-	./configure ...
-
-    or:
-
-	CFLAGS="-I/some/directory" \
-	CPPFLAGS="-I/some/directory" \
-	CXXFLAGS="-I/some/directory" \
-	DSOFLAGS="-L/some/directory" \
-	LDFLAGS="-L/some/directory" \
-	./configure ...
-
-    The "--enable-debug" option compiles CUPS with debugging information
-    enabled.  Additional debug logging support can be enabled using the
-    "--enable-debug-printfs" option - these debug messages are enabled using the
-    CUPS_DEBUG_LOG environment variable at run-time.
-
-    CUPS also includes an extensive set of unit tests that can be used to find
-    and diagnose a variety of common problems - use the "--enable-unit-tests"
-    configure option to run them at build time.
-
-    On macOS, use the "--with-archflags" option to build with the correct set of
-    architectures:
-
-        ./configure --with-archflags="-arch i386 -arch x86_64" ...
-
-        Note: Current versions of macOS DO NOT allow installation to
-        /usr with the default system integrity settings.  In addition,
-        we do not recommend replacing the CUPS supplied with macOS
-        because not all versions of CUPS are compatible with every
-        macOS release, and because software updates will replace parts
-        of your local installation potentially rendering your system
-        unusable.
-
-    Once you have configured things, just type:
-
-	make ENTER
-
-    or if you have FreeBSD, NetBSD, or OpenBSD type:
-
-	gmake ENTER
-
-    to build the software.
-
-
-TESTING THE SOFTWARE
-
-    Aside from the built-in unit tests, CUPS includes an automated test
-    framework for testing the entire printing system.  To run the tests, just
-    type:
-
-	make check ENTER
-
-    or if you have FreeBSD, NetBSD, or OpenBSD type:
-
-	gmake check ENTER
-
-    The test framework runs a copy of the CUPS scheduler (cupsd) on port 8631
-    in /tmp/cups-$USER and produces a nice HTML report of the results.
-
-
-INSTALLING THE SOFTWARE
-
-    Once you have built the software you need to install it.  The "install"
-    target provides a quick way to install the software on your local system:
-
-	make install ENTER
-
-    or for FreeBSD, NetBSD, or OpenBSD:
-
-	gmake install ENTER
-
-    Use the BUILDROOT variable to install to an alternate root directory:
-
-        make BUILDROOT=/some/other/root/directory install ENTER
-
-    You can also build binary packages that can be installed on other machines
-    using the RPM spec file ("packaging/cups.spec") or EPM list file
-    ("packaging/cups.list").  The latter also supports building of binary RPMs,
-    so it may be more convenient to use.
-
-    You can find the RPM software at:
-
-	http://www.rpm.org/
-
-    The EPM software is available at:
-
-	http://www.msweet.org/
-
-
-CREATING BINARY DISTRIBUTIONS WITH EPM
-
-    The top level makefile supports generation of many types of binary
-    distributions using EPM.  To build a binary distribution type:
-
-	make <format> ENTER
-
-    or
-
-	gmake <format> ENTER
-
-    for FreeBSD, NetBSD, and OpenBSD.  The <format> target is one of the
-    following:
-
-	epm       - Builds a script + tarfile package
-	bsd       - Builds a *BSD package
-	deb       - Builds a Debian package
-	pkg       - Builds a Solaris package
-	rpm       - Builds a RPM package
-	slackware - Build a Slackware package
-
-
-GETTING DEBUG LOGGING FROM CUPS
-
-    When configured with the "--enable-debug-printfs" option, CUPS compiles in
-    additional debug logging support in the scheduler, CUPS API, and CUPS
-    Imaging API.  The following environment variables are used to enable and
-    control debug logging:
-
-        CUPS_DEBUG_FILTER  Specifies a POSIX regular expression to control
-	                   which messages are logged.
-	CUPS_DEBUG_LEVEL   Specifies a number from 0 to 9 to control the
-	                   verbosity of the logging. The default level is 1.
-        CUPS_DEBUG_LOG     Specifies a log file to use.  Specify the name "-"
-	                   to send the messages to stderr.  Prefix a filename
-			   with "+" to append to an existing file.
-
-
-REPORTING PROBLEMS
-
-    If you have problems, READ THE DOCUMENTATION FIRST!  If the documentation
-    does not solve your problems, please post a message on the users forum at:
-
-        http://www.cups.org/
-
-    Include your operating system and version, compiler and version, and any
-    errors or problems you've run into.  The "config.log" file and the output
-    from the configure script and make should also be sent, as it often helps to
-    determine the cause of your problem.
-
-    If you are running a version of Linux, be sure to provide the Linux
-    distribution you have, too.

+README - CUPS v2.2.4 - 2017-04-18
+=================================
+
+Looking for compile instructions?  Read the file "INSTALL.md" instead...
+
+
+INTRODUCTION
+------------
+
+
+CUPS is a standards-based, open source printing system developed by Apple Inc.
+for macOS® and other UNIX®-like operating systems.  CUPS uses the Internet
+Printing Protocol ("IPP") and provides System V and Berkeley command-line
+interfaces, a web interface, and a C API to manage printers and print jobs.  It
+supports printing to both local (parallel, serial, USB) and networked printers,
+and printers can be shared from one computer to another, even over the Internet!
+
+Internally, CUPS uses PostScript Printer Description ("PPD") files to describe
+printer capabilities and features and a wide variety of generic and device-
+specific programs to convert and print many types of files.  Sample drivers are
+included with CUPS to support many Dymo, EPSON, HP, Intellitech, OKIDATA, and
+Zebra printers.  Many more drivers are available online and (in some cases) on
+the driver CD-ROM that came with your printer.
+
+CUPS is licensed under the GNU General Public License and GNU Library General
+Public License versions 2.  See the file "LICENSE.txt" for more information.
+
+
+READING THE DOCUMENTATION
+-------------------------
+
+Once you have installed the software you can access the documentation (and a
+bunch of other stuff) online at:
+
+    http://localhost:631/
+
+If you're having trouble getting that far, the documentation is located under
+the "doc/help" directory.
+
+Please read the documentation before asking questions.
+
+
+GETTING SUPPORT AND OTHER RESOURCES
+-----------------------------------
+
+If you have problems, READ THE DOCUMENTATION FIRST!  We also provide two mailing
+lists which are available at:
+
+    https://lists.cups.org/mailman/listinfo
+
+See the CUPS web site at <https://www.cups.org/> for other resources.
+
+
+SETTING UP PRINTER QUEUES USING YOUR WEB BROWSER
+------------------------------------------------
+
+CUPS includes a web-based administration tool that allows you to manage
+printers, classes, and jobs on your server.  Open the following URL in your
+browser to access the printer administration tools:
+
+    http://localhost:631/admin/
+
+*Do not* use the hostname for your machine - it will not work with the default
+CUPS configuration.  To enable administration access on other addresses, check
+the "Allow Remote Administration" box and click on the "Change Settings" button.
+
+You will be asked for the administration password (root or any other user in the
+sys/system/root/admin/lpadmin group on your system) when performing any
+administrative function.
+
+
+SETTING UP PRINTER QUEUES FROM THE COMMAND-LINE
+-----------------------------------------------
+
+CUPS works best with PPD (PostScript Printer Description) files.  In a pinch you
+can also use System V style printer interface scripts.
+
+CUPS includes several sample PPD files you can use:
+
+    Driver                         PPD Name
+    -----------------------------  ------------------------------
+    Dymo Label Printers            drv:///sample.drv/dymo.ppd
+    Intellitech Intellibar         drv:///sample.drv/intelbar.ppd
+    EPSON 9-pin Series             drv:///sample.drv/epson9.ppd
+    EPSON 24-pin Series            drv:///sample.drv/epson24.ppd
+    Generic PCL Laser Printer      drv:///sample.drv/generpcl.ppd
+    Generic PostScript Printer     drv:///sample.drv/generic.ppd
+    HP DeskJet Series              drv:///sample.drv/deskjet.ppd
+    HP LaserJet Series             drv:///sample.drv/laserjet.ppd
+    OKIDATA 9-Pin Series           drv:///sample.drv/okidata9.ppd
+    OKIDATA 24-Pin Series          drv:///sample.drv/okidat24.ppd
+    Zebra CPCL Label Printer       drv:///sample.drv/zebracpl.ppd
+    Zebra EPL1 Label Printer       drv:///sample.drv/zebraep1.ppd
+    Zebra EPL2 Label Printer       drv:///sample.drv/zebraep2.ppd
+    Zebra ZPL Label Printer        drv:///sample.drv/zebra.ppd
+
+Run the "lpinfo -m" command to list the available drivers:
+
+    lpinfo -m
+
+Run the "lpinfo -v" command to list the available printers:
+
+    lpinfo -v
+
+Then use the correct URI to add the printer using the "lpadmin" command:
+
+    lpadmin -p printername -E -v device-uri -m ppd-name
+
+Network printers typically use "socket" or "lpd" URIs:
+
+    lpadmin -p printername -E -v socket://11.22.33.44 -m ppd-name
+    lpadmin -p printername -E -v lpd://11.22.33.44/ -m ppd-name
+
+The sample drivers provide basic printing capabilities, but generally do not
+exercise the full potential of the printers or CUPS.
+
+CUPS also supports IPP Everywhere printers using the "everywhere" model, for
+example:
+
+    lpadmin -p printername -E -v ipp://11.22.33.44/ipp/print -m everywhere
+
+
+PRINTING FILES
+--------------
+
+CUPS provides both the System V "lp" and Berkeley "lpr" commands for printing:
+
+    lp filename
+    lpr filename
+
+Both the "lp" and "lpr" commands support printing options for the driver:
+
+    lp -o media=A4 -o resolution=600dpi filename
+    lpr -o media=A4 -o resolution=600dpi filename
+
+CUPS recognizes many types of images files as well as PDF, PostScript, and text
+files, so you can print those files directly rather than through an application.
+
+If you have an application that generates output specifically for your printer
+then you need to use the "-oraw" or "-l" options:
+
+    lp -o raw filename
+    lpr -l filename
+
+This will prevent the filters from misinterpreting your print file.
