Welcome to Gutenprint 5.1.7!  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, 10.4,
and 10.5) 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 an enhanced Print
plug-in for GIMP that replaces the plug-in packaged with GIMP, and
Ghostscript and CUPS drivers, as well as Foomatic data supporting the
Ghostscript driver.

Gutenprint has been renamed in order to clearly distinguish it from
GIMP.  While this package started out as the original Print plugin
for GIMP, it has expanded into a collection of general purpose
printer drivers, and the new, 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.

Gutenprint currently supports about 700 printer models.

Gutenprint 5.1.7 is a development release of Gutenprint 5.1.

*** NOTE TO PACKAGERS: This is a DEVELOPMENT version of Gutenprint.
    It should not be packaged as the principal release of Gutenprint
    in any OS or distribution release.  The most recent stable release
    (the release with the second number being even -- for example,
    5.0.1) should be used for that.

    If you need a bug fix from the development release, you should
    backport it to the stable release if possible.  If you really
    think you need the development release, please contact us at
    gimp-print-devel@lists.sourceforge.net well in advance of your
    packaging deadline to discuss your particular needs with us.  We
    normally back port bug fixes from the development release to the
    next stable release, and we back port new printers and new
    capabilities if we determine it's safe to.

    By all means feel free to deliver this release as a
    "gutenprint-unstable" release if you want to make bleeding edge
    packages available as an option.

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

I) GENERAL REQUIREMENTS

Gutenprint will run on any reasonably modern computer running Linux,
Macintosh OS X (10.2 or above), Solaris, or any other UNIX-like
operating system.  If you plan to compile this package from source,
you will also need an ANSI C compiler, such as gcc (recommended).  A
compiler is not required if you are installing a pre-compiled package.

Processor and memory requirements vary depending upon the printer and
runtime options selected; it is suggested that you have at least 64 MB
of memory for general purpose printing, 256 MB or more for high
quality printing on a good printer, and 1 GB or more for large format
printing at high resolution.  You should have at least 50 MB of free
disk space to compile and install Gutenprint.  Disk space requirements
for printing will vary depending upon how you use Gutenprint, but are
generally modest except as noted below.  We recommend a processor
speed of at least 300 MHz.  Fast printers may require a faster
processor to achieve maximum printing speed.

For general use, you should have the Common UNIX Printing System, CUPS
(version 1.1.15 or above) or Foomatic (2.0 or above) installed.
Please the rest of the release notes, in particular the Exceptions and
Workarounds, for full details on installation, as there is important
information to be aware of.  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 enhanced Print plug-in for GIMP requires GIMP 2.0 or above (GIMP
2.2 recommended).  This plug-in will work with any printing system,
and offers a comprehensive user interface to control all aspects of
the printing process.  If you are printing photographs in large format
from GIMP at very high resolution, disk space requirements may be
substantial, and we recommend at least 2 GB of free disk space for
that purpose.

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.  This driver should be used in conjunction with
Foomatic to configure printers.

Users of Macintosh OS X 10.2 (Jaguar), 10.3 (Panther), 10.4 (Tiger),
and 10.5 (Leopard) 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 strongly 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).  The printing system used with these versions
of OS X is not compatible with Gutenprint.  OS X 10.2 and above use
CUPS as the basis of the printing system, which is compatible with
Gutenprint.

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

	EPSON Stylus Photo RX685

	(Note that a number of the PictureMate printers that were
	previously included generated grossly incorrect output.  Not
	all of the PictureMate printers have been fully tuned at this
	point.)

      * Canon inkjet printers:
        Canon PIXMA MP520 (#1872394)
	Canon PIXMA iP6000D

   2) Printing for the Canon PIXMA iP4500 has been fixed (#1834153).

   3) Printing near the bottom of the page has been improved for many
      modern Epson inkjet printers.  In addition, we have determined
      that most of these printers can print with consistent high
      quality at 2880x2880 and 5760x2880 DPI.  Therefore, these
      resolutions will be used for Ultra Photo and Best qualities
      respectively on these printers.

      Printers affected include:

      * Stylus Photo R800, R1800, PM-G820

      * Stylus Photo R2400

      * All printers using Claria ink

   4) Full bleed printing now works properly on the Epson Stylus Photo
      R2400.

   5) The Epson Stylus C120 now allows printing at 2880x2880 and
      5760x2880.  However, print quality near the bottom of the page
      may be poor, and these settings are therefore not used for Ultra
      Photo and Best quality.

   5) The ink drop sizes on the Epson Stylus Photo printers using
      Claria ink have been retuned, yielding improved quality at lower
      resolutions.

   6) A problem with determining the system printer queues in the GIMP
      plugin on certain systems using languages other than English has
      been fixed.

   7) Envelope paper sizes are now offered in both portrait and
      landscape form factor, as some printers expect envelopes to be
      fed long edge first while some expect them to be fed short edge
      first.

   8) PCL laser printers now offer paper trays with adjustable guides.
      Many laser printers use adjustable guides for manual feed of
      papers narrower than letter size.

   9) The GIMP plugin now offers reset buttons for individual
      settings, so it is possible to reset a single setting to its
      default without resetting all settings.

   9) Various new controls and settings have been added to assist in
      printer calibration.  While the tools for using these controls
      are not yet created, these tools will assist in calibrating
      printers in the future.

      * The Epson driver now offers additional controls for adjusting
      	the relationship between light and dark ink:

	+ The Value parameters (such as Light Cyan Value) specify the
	  relative darkness of the light vs. dark inks.

	+ The Cutoff parameters now specify the point at which the
	  darker ink is first used, relative to the value of the light
	  ink.

	+ The Scale parameters now specify the amount of light ink
	  used (essentially the density of the light ink).  This is
	  the same as the parameters previously called Cutoff.

      * The Epson driver now exposes as defaults the actual GCR
        settings used for the printer, paper, and ink combination in
        use.

      * The Epson driver now allows passing low level settings such as
        printer base resolution, ink drop size selection, and relative
        ink drop size as parameters.  The ink drop size can be
        accessed in the GIMP plugin, while the base resolution and ink
        drop size selection can only be used via the test pattern
        generator or other application that allows setting integer
        parameters.

      * Two new dither algorithms, Segmented and Segmented New, have
	been added.  These are not intended for normal use, and will
	normally behave like Ordered and Ordered New.  However, if Raw
	color correction is selected and a printer with multiple drop
	sizes is used, the range of input will be divided up such that
	the high order bits will select the drop size to be used and
	the lower bits will specify the amount of ink.  High order
	bits of 0 indicate that all drop sizes should be used.

	For example, if a printer offers 3 drop sizes (2 bits), the
	range of 0-16383 will print all drop sizes normally (with the
	range of 0-16383 being scaled to 0-65535), 16384-32767 will
	use the small drop size, and so forth.

	This is intended to assist in tuning ink drop sizes.

      * A new parameter allowing dumping out of color correction state
	(lookup tables, GCR data, curves, etc.) has been added, and is
	accessible in the GIMP plugin.  At present, this data cannot
	be used directly, but it is intended that in the future this
	mechanism be used to allow calibration information to be saved
	and restored.


----------------

* NEW FEATURES AND FIXES IN GUTENPRINT 5.1.6:

   1) A bug involving excessive memory consumption in certain cases
      has been fixed.  Printing multiple page documents on Canon
      inkjet printers with the Duplex option set to Long Edge resulted
      in very large memory consumption on alternate pages, which was
      not released until the job completed.  For example, in color at
      600 DPI, the memory consumption would be about 120 megabytes on
      alternate pages, so printing a 100 page document would result in
      6 GB of memory consumption.  Depending upon the system, the
      results might be that the job would fail to print or would only
      partially print, the system might run very slowly while the job
      was being processed, or other components of the system might
      fail.

   2) The Ordered New dither algorithm has been improved to produce
      smoother output.


----------------

* NEW FEATURES AND FIXES IN GUTENPRINT 5.1.5:

   1) New printers supported in this release:

      * Epson inkjet printers:

      	EPSON Stylus C110
      	EPSON Stylus C120
      	EPSON Stylus D120
      	EPSON PX V780

      * PCL laser printers:

      	Sharp AR-M257

   2) Preliminary support for the following printers:

      * Canon inkjet printers:

      	Canon PIXMA iP8500
      	Canon PIXMA Pro 9500
	Canon PIXMA MP610
	Canon i80

   3) The printer maintenance utility for EPSON inkjet printers,
      escputil, now reports status more reliably.  Previously some
      people reported errors of the form "Unknown IEEE 1284.4 error";
      these errors have been resolved.

      In addition, escputil now correctly reports the ink color for
      certain printers (in particular, printers using Claria (TM) inks
      and printers using alternate ink cartridges (for example, the
      Stylus Photo 1400 that allows either a photo black or a matte
      black ink cartridge to be installed).

   4) A few remaining problems with the PPD files have been fixed
      (paper sizes for certain dye sublimation printers, and "Okidata"
      has been renamed "Oki" to match the PPD specification for that
      manufacturer).

   5) A new dither algorithm, Ordered New, has been added.  This
      dither algorithm is most likely to improve output at low
      resolutions, particularly when printing black and white.  It
      will only help on printers offering multiple drop sizes.

   6) The color correction for the Canon PIXMA iP4200 has been improved.

   7) The PPD file parsing code in the Postscript driver has been
      rewritten.

      We determined that the PPD file parsing code in the Postscript
      driver was actually borrowed from CUPS, which is licensed under
      the LGPL v2 and GPL v2 only.  However, the remainder of the core
      of Gutenprint is licensed under GPL v2 or higher.  This is not
      directly a license conflict -- it is permissible to mix code
      licensed under the GPL v2 with code licensed under GPL v2 or
      above -- but it means that Gutenprint (5.1.3 and 5.1.4, the two
      releases that used this code) itself could only be licensed
      under GPL v2, which is not the desire of this project, as it
      would not permit usage with code licensed under GPL v3 (or
      higher) only.

      To resolve this, we wrote new PPD file parsing code that is
      licensed under GPL v2 or above.  Therefore, Gutenprint may now
      be used with any code licensed as GPL v2 or any later version of
      the GPL.

   8) The CUPS driver in Gutenprint, and all associated utilities, are
      now licensed as GPL v2 or higher.  That code was previously
      licensed as GPL v2 only.  While that did not cause any direct
      problems, since the CUPS driver does not form a library that
      other code may wish to link against, it was licensed differently
      from the rest of the Gutenprint project.  That is now resolved,
      and the entire Gutenprint code base is now licensed as GPL v2 or
      higher.

	Canon SELPHY ES20(*)
	Shinko CHC S9045

	(*) Note that these printers may not work on all systems due to
	    communication requirements.

   3) The following printers are no longer supported going forward in
      Gutenprint 5.1 and beyond.  We recommend that users switch to
      the HPIJS driver package (the printer part of HPLIP), available
      from http://hplip.sourceforge.net.  This package is licensed
      under the GPL and BSD licenses.

      These printers will continue to be supported in Gutenprint 5.0.

      All monochrome laser printers previously supported continue to
      be supported.  In addition, the following wide format printers
      that are not supported by HPLIP continue to be supported by
      Gutenprint:

	HP DesignJet 230
	HP DesignJet 250C
	HP DesignJet 430
	HP DesignJet 450C
	HP DesignJet 455CA
	HP DesignJet 488CA

	HP DesignJet 750C Plus
	HP DesignJet 750C
	HP DesignJet 2500CP
	HP DesignJet 3500CP
	HP DesignJet ColorPro CAD

   4) All native CUPS PPD files are now perfectly compliant with the
      PPD specification, as tested under CUPS 1.2.  Fixing this
      requires some changes to the internal resolution names.  These
      changes should be transparent if PPD files are updated with
      cups-genppdupdate.5.1.

   5) Borderless printing on the Epson Stylus Photo 2200 now works
      correctly.

   6) A bug in which certain data was not printed correctly by Canon
      inkjet printers was fixed (in areas where the entire area was
      filled with maximum color density, some lines could be silently
      discarded).

   7) Various fixes for the Canon iP4000, iP4200, and i560.

   8) The paper size for the CD - Custom paper size has been changed
      to 120 mm from 118.8 mm to allow correct printing from CUPS.

   9) A compile problem on Solaris has been fixed.

   10) It is now possible to specify the printer model to all escputil
      commands, via the -m option.  It is no longer necessary to use
      the -u option to specify a new printer vs. an old printer.

   11) The Postscript driver now sends device-specific settings, such
      as media type, to the print command.

   12) The Epson driver will not select resolutions higher than
      5760x1440 for the automatic quality settings, as we have
      determined that many current printers offer poor quality at the
      bottom of the page with resolutions of 2880x2880 and 5760x2880.
      We have not removed these resolutions altogether, as they may
      work well for certain applications, but they will not be
      automatically selected by the Best or Ultra Photo quality
      settings.

   13) A problem where in some cases certain options were not handled
      correctly by the CUPS driver has been fixed.  In particular,
      yes/no options such as borderless printing were not handled
      correctly in all cases when the printing system is CUPS 1.2 or
      1.3.


----------------

* NEW FEATURES AND FIXES IN GUTENPRINT 5.1.3:

  1) The Canon PIXMA iP4300 and related printers now print black
     properly.

  2) Margins have been improved for Canon PIXMA printers.

  3) Borderless printing has been improved for many of the Epson
     R200/R300 series printers and related multifunction devices.

  4) A build problem on certain systems has been fixed.


----------------

* NEW FEATURES AND FIXES IN GUTENPRINT 5.1.2:

  1) Improved tunings for Epson printers using Claria inks.

     The driver for the Stylus Photo 1400 has two separate quality
     settings for 720x360 and 720 DPI.  The 720x360 DPI Enhanced and
     720 DPI High Quality options offer improved quality at some cost
     in printing speed.  The small format Claria-based printers (R260,
     R390, RX580, and related printers) offer 720x360 and 720 DPI
     modes approximately equal in quality to the Enhanced and High
     Quality modes on the 1400 without a speed penalty.

  2) A problem whereby in some situations printers using Claria inks
     did not print black ink has been fixed.

  3) A problem with the Postscript driver always printing in grayscale
     has been fixed.  This problem was apparently introduced in 5.1.1.

  4) The range of sizes for printing custom CD's has been extended
     down to 65 mm in both the Epson and Canon drivers.

  5) The Epson Stylus Photo RX590 is now supported.

  6) Borderless printing on the Epson Stylus Photo RX400, RX420,
     RX425, RX430, RX500, RX510, RX600, RX630, and RX640 now works
     correctly.

  7) Printing to CD's on Epson printers now works correctly if the
     image is not placed at the top of the page.

  3) A minor border problem with the R800 and related printers has
     been fixed.  The standard bottom border is now slightly wider to
     eliminate the very bottom of the print from being chopped off.

  4) Some Canon printers have been renamed from "Multipass" to
     "Pixma".

  5) A build problem with the CUPS driver on some systems (in
     particular, OS X and any system where --disable-nls is used) has
     been fixed.

  6) The CUPS PPD files now use the correct UTF-8 encoding.

  7) Printing to CD's has been re-enabled for the Canon PIXMA iP4200.

  8) CD printing for the Canon PIXMA iP4000 has been fixed.

  9) The Canon driver now also supports the CD fine adjustment controls.

     Windows hosts has been fixed (bug 1625202).

  12) The Postscript driver now handles CMYK input correctly, fixing a
     problem with Cinepaint (bug 1701954).

  13) The Postscript driver and UI library now handle setting the
     locale correctly.

  14) The PPD file updater, cups-genppdupdate.5.1, now handles the -n
     (don't do anything) correctly.  In addition, it handles --help
     and --version.

       Epson Stylus CX5000F
       Epson Stylus CX6000
       Epson Stylus CX7000F

     * Lexmark inkjet and compatible printers:

       Compaq IJ1200
       Lexmark X73

     * PCL laser printers (monochrome only):

       Lexmark Optra E220
       Xerox WorkCentre M118

  2) CUPS 1.2 is now supported using on-the-fly PPD file generation.
     In addition, the resolution names are all compliant with the PPD
     specification.  cups-genppdupdate correctly updates on-the-fly
     PPD files.

  3) The native CUPS driver offers a new Shrink Page If Necessary to
     Fit Borders option, enabling the user to choose how to fit the
     output to the imageable area of the page.  This is useful when a
     printer offers a choice of imageable areas, typically normal
     (which has margins) and full bleed (which allows printing to the
     edge of the paper, or even beyond).  The following options are
     available:

     * Shrink (default): the output is shrunk if necessary to fit the
       imageable area of the page.  If a printer is capable of
       borderless operation but normal margins are selected, the
       output will be shrunk.  This will print the entire page
       (nothing will be lost), but will not preserve the dimensions of
       the printout.  For example, a line intended to be 10 cm long
       may print smaller than that.

     * Crop: the output is cropped if necessary to fit the imageable
       area of the page.  The dimensions of the page will be preserved
       (a line intended to be 10 cm long will print out exactly 10
       cm), but the edges of the output may be truncated (cropped).

     * Expand: the output is expanded to fit the maximum possible
       imageable area of the page.  When selected on printers capable
       of full bleed output, in conjunction with any other necessary
       options, the output will be expanded to match the maximum page
       dimension.  The dimensions of the page will be expanded if
       necessary beyond the page size; a line intended to be 10 cm
       long may print longer than that.

     This option has no effect on printers not capable of full bleed
     or other expanded margins.  It also has no effect when printing
     to CD's or the like.

  4) Support for GIMP 1.2 has been removed.

  5) An experimental PostScript driver has been added, enabling use of
     all PPD file options in the enhanced GIMP plugin.  This is a work
     in progress.

  6) Epson inkjet printers now correctly support borderless printing.
     In addition, printing at the top and bottom of the page has been
     improved on printers that support borderless printing, although
     this is still not perfect in all cases.

     Certain printers (in particular the C/D8x and C6x series) do not
     print correctly to the bottom of the page with all colors.  This
     problem is understood, but we do not know when a fix will be
     available.

  7) The list of resolutions supported on newer Epson printers has
     been changed; resolutions of 5760x1440, 2880x2880, and 5760x2880
     (as appropriate) have been added, replacing various 1440x2880
     enhanced resolutions.

  8) The output for the Canon PIXMA printers has been improved.

  9) The Canon driver now supports DuplexNoTumble for the PIXMA
     iP4000.

 10) Roll printing now works correctly on the Epson Stylus Photo
     R800.


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

III) EXCEPTIONS AND WORKAROUNDS

A) GENERAL ISSUES

  1) 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.


----------------

B) BUILD/INSTALLATION ISSUES

  1) 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 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. 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 /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 a default, 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.

     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.

  2) There is a known translation problem building the PPD files used
     by the CUPS driver such that on many systems all of the PPD
     files are in the English language.  This causes CUPS tools, such
     as KUPS or http://localhost:631 to display many copies of each
     PPD file, all in the English (en) language.  In fact, the PPD
     files should be translated into many different languages.

     The PPD files are created by a program named "genppd" in the
     src/cups directory.  This program is called once for each
     language, and creates all of the PPD files for the language in
     one shot.

     The command 'zgrep' can be used to determine if genppd is
     creating the PPD files correctly, as follows:

	 src/cups$ zgrep LanguageVersion ppd/*/pcl-4.ppd.gz
	 ppd/C/pcl-4.ppd.gz:*LanguageVersion: English
	 ppd/da/pcl-4.ppd.gz:*LanguageVersion: Danish
	 ppd/en_GB/pcl-4.ppd.gz:*LanguageVersion: English-GB
	 ...

     If the PPD file for each language has a different language
     version, the genppd program operated correctly.  If instead the
     output looks like this:

	 src/cups$ zgrep LanguageVersion ppd/*/stp-pcl-4.5.1.ppd.gz
	 ppd/C/stp-pcl-4.5.1.ppd.gz:*LanguageVersion: English
	 ppd/da/stp-pcl-4.5.1.ppd.gz:*LanguageVersion: English
	 ppd/en_GB/stp-pcl-4.5.1.ppd.gz:*LanguageVersion: English
	 ...

     the program did not operate correctly.

     If you do not have 'zgrep' on your system, you can gunzip the
     PPD files, and use

	 grep LanguageVersion ppd/*/stp-pcl-4.5.1.ppd

     to accomplish the same test.

     The normal mechanism for performing translations is to set the
     LANG environment variable to the appropriate language prior to
     running the program.  This normally causes the program to search
     the translations (normally in /usr/share/locale or
     /usr/lib/locale) for the chosen language.  When a specially
     marked string is used, a special macro calls `gettext()' on the
     string to retrieve the translation, and substitutes the
     translation for the string in question.

     There are two problems with this approach in the context of
     genppd.  The translation engine is intended to be used after
     installation, not during build, and this causes problems.

     i) At the time genppd is run, the translations have not been
	installed in the normal system directories.  Fortunately,
	it's possible to tell the translation machinery (via
	bindtextdomain) to look elsewhere for the translation
	catalogs.  What we do is install the catalogs in a temporary
	directory under src/cups, and tell genppd to instruct the
	translation machinery to look there.  This workaround is
	straightforward, and doesn't normally cause problems.

     ii) LANG only lets us pick a valid locale (normally determined by
	listing the directories in /usr/share/locale or
	/usr/lib/locale).  Unfortunately, while language codes (which
	form the base of locales) are standard, the actual locale
	names aren't always.  On some systems, the locale names are
	just the language base names; on others, they are the
	language names concatenated with country codes (e. g. en_US),
	while on others they are language codes concatenated with
	character sets.  We are not aware of any workaround for this,
	possibly short of actually running make install and then
	rebuilding the PPD's.  'make install' will install the
	message catalogs, and that may create the necessary locale
	directories.  This is not exactly a very elegant approach.

     The GNU gettext library (libintl.a) provides another environment
     variable, LANGUAGE, which unconditionally looks up translations
     according to the language, ignoring LANG and the LC_*
     environment variables that are normally used for translation.
     This library is no longer included with Gutenprint
     (--with-included-gettext will not work).  Install the GNU
     gettext package first if you need libintl.a.  Many systems
     provide translation machinery in their standard libraries, and
     it may not always be best to use foreign libraries to replace
     standard system functionality.

     We have chosen to use LANGUAGE for this purpose, as the GNU
     gettext library appears to offer the most reliable translation,
     and LANGUAGE appears to offer the most reliable mechanism.  We
     have actually found that LANG and LC_* can interfere with
     LANGUAGE, thus we do not use both.

     To determine if the translations are working, you must actually
     inspect the PPD files.  You will need to

     cd src/cups/ppd/sv
     gunzip *
     more *

     or the like to determine if this is successful.  In particular,
     look for LanguageVersion, and make sure that it is correct (it
     should be "Swedish" in the sv directory, for example), and also
     make sure that the paper sizes are also translated.  We
     currently suggest using the Swedish translation for this purpose
     as it is the most complete.

     If packagers find that the PPD files are all in English, rather
     than translated into the appropriate languages, we suggest the
     following:

     i) Install GNU gettext (libintl).  If your system is not based
	on GNU libc (Linux usually is based on GNU libc; BSD,
	Solaris, IRIX, etc. are not), you will need this to have any
	possibility of creating the translated PPD files.

     ii) Run 'make install' to install the package (including the
	message catalogs) onto the system first, and then do the
	following:

	cd src/cups
	rm ppd-stamp
	make

	to rebuild the PPD files.  Having the message catalogs on the
	system may permit this to succeed.

     iii) Ensure that your system actually has locales named 'sv',
	'pl', and all of the other supported languages, and change
	LANGUAGE to something more appropriate (most likely LANG,
	LC_MESSAGES, or LC_ALL).

     iv) Build the PPD files on a Linux-based system; they are
	portable.

     v) Use --disable-translated-cups-ppds on the configure command line
	to suppress the translated PPD files altogether.

     Please feel free to contact us about this issue.

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

     i) Before installing any new release of Gutenprint 5.1, 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.openprinting.org/foomatic.html) and the Gutenprint
	site (http://gimp-print.sourceforge.net) for updated
	instructions about this.

     ii) 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.

     iii) The Foomatic data is version locked to the Gutenprint release
	installed on the system.  For example, PPD files generated
	with the Foomatic data for release 5.1.0 will not work with
	the ijsgutenprint in release 5.1.1.  This is to prevent
	accidentally using incorrect data, which could cause incorrect
	function to take place.

  4) There is a known complication building "escputil" that causes
     problems on some systems.  "escputil" uses the "readline"
     package, to support command editing and history within the
     program.  Unfortunately, linking programs with "readline" often
     requires linking against additional libraries, and the exact
     library depends upon the system (e. g. not all Linux systems have
     the same requirements).

     The configure script attempts to determine which additional
     library must be linked against.  It tries using the following
     libraries in this order to build a test executable:

     -lncurses
     -lcurses
     -ltermcap
     no additional libraries

     The reason it tries other libraries first is that some systems
     will link successfully, but only fail when an attempt is made to
     actually call readline.  Therefore, we assume that additional
     libraries are required.  Since we try the extra libraries in
     order from most recent to oldest, we expect that the first one we
     find will be appropriate.  For example, if the "ncurses" library
     is the standard on a given system, the "termcap" library may be
     provided for back compatibility, but it is unlikely that
     "termcap" will be the standard with "curses" or "ncurses" being
     provided for compatibility only (so that the link will succeed
     but the command will use the incorrect library).

     As this procedure is not failsafe, we provide the following
     configure options to control this behavior:

     ./configure --with-readline=yes  (the default; attempts to
				      determine the correct library
				      to link against)

     ./configure --with-readline=no   (turns off use of readline
				      altogether)

     ./configure --with-readline=only (specifically instructs
				      configure to not attempt to
				      link against any other
				      libraries)

     ./configure --with-readline=libs (specifies the libraries to be
				      linked against)

     An hypothetical (this won't work anywhere!) example of the
     latter would be

     ./configure --with-readline='-lncurses -ltermcap'

     Note that configure will not allow readline to be used if it
     cannot successfully build the test program, regardless of the
     option selected.  If you are having difficulty getting escputil
     to build, we suggest using --with-readline=no.  The commands
     used within escputil are very short and seldom require
     significant editing.
