Raw Blame History

This is gimp-print version 4.0.3, a stable release in the 4.0 line.
This software includes the Print plug-in for the Gimp (1.0, 1.1, and
1.2), and GhostScript and CUPS drivers. The support for printers in
GhostScript and CUPS is identical to the support for these printers in
the Print plugin -- they use the identical code base. Please read
Ghost/README and CUPS/README.txt for more information on this.
Gimp-Print 4.0.4 contains the following fixes over Gimp-Print 4.0.3:
1) The gimp-print configure script failed on version of the Gimp older
than 1.1.20 or thereabouts, give or take a few versions. That
should now work correctly. This bug was present in 4.0b2 and was
fixed in 4.0b3; it reappeared due to a system upgrade on the build
system.
2) A bug in the color conversion routine caused very serious
posterization effects in certain images (specifically, in regions
of very low saturation) in Photograph mode.
Gimp-Print 4.0.3 contains the following fixes over Gimp-Print 4.0.2:
1) The fix to the GhostScript driver in 4.0.2 broke the handling of
printer-specific variables. This is now fixed.
2) The documentation in Ghost/README contains more information on the
color settings.
3) The HP DeskJet 1200C should now operate correctly in color mode.
4) The CUPS utility named 'calibrate' has been renamed
'cups-calibrate' because of name collisions on some systems.
Gimp-Print 4.0.2 contains the following fixes over Gimp-Print 4.0.1:
1) The GhostScript driver (used either alone or with foomatic) now
prints multi-page documents correctly. 4.0.0, 4.0.1, and some
earlier versions printed each page progressively paler.
2) The CUPS driver should now print with proper density on all
printers. In 4.0.0 and 4.0.1 it printed too pale with most
printers.
3) The Canon driver failed (in GhostScript and CUPS) if no InkType was
specified. It now defaults to a reasonable choice based on the
printer model.
Gimp-Print 4.0.1 contains the following fixes over Gimp-Print 4.0.0:
1) The copy of escputil.c in the Ghost subdirectory was older than the
copy at top level.
2) escputil in either location would fail to compile without the GNU
version of getopt() due to a syntax error.
3) The INSTALL file referred to an old version of gimp-print.
4) A man page for escputil is provided.
Gimp-Print 4.0 is a major release of the Gimp Print plugin and
associated stp GhostScript driver and CUPS driver. Among the new
features over the 2.0 (distributed with the Gimp 1.0) and 3.0
(distributed with some versions of the Gimp 1.1) releases are:
1) Support for many more printers, including advanced Epson Stylus
printers and many Canon BubbleJets. This software now fully
supports 6 color printers with variable dot sizes.
2) Greatly improved print quality. Photographs can now be printed
with excellent (certainly not "perfect") color fidelity and
smoothness of tone.
3) A much-enhanced GUI in the Gimp plugin, particularly for users of
recent Gimp 1.1 releases. This GUI offers better placement
controls, a live preview (for Gimp 1.1.21+/1.2 only), and other
control improvements.
4) Included Ghostscript and CUPS drivers derived from the same source
base as the Print plugin, enabling general printing of the same
quality as printing from the Gimp.
5) Included support from the Foomatic project (see
http://www.linuxprinting.org/foomatic.html), greatly easing the
pain of configuring printers. Foomatic is a system for using free
software printer drivers with common spoolers on Unix. It supports
LPD, PDQ, CUPS, the VA Linux LPD, and LPRng.
6) Greatly improved performance in many common cases. While
photographs rendered in the highest quality modes still require
considerable computation, typical text and graphics now render much
faster. There are some new special-purpose extremely fast
dithering algorithms that can be used.
7) The default color and dithering settings are much more accurate
than in previous releases.
8) Users of the Print plugin in the Gimp: PLEASE NOTE THAT THE printrc
FILE FORMAT IN THIS RELEASE IS NOT BACKWARD COMPATIBLE WITH THE
FORMAT IN 3.0 AND PREVIOUS RELEASES! The main issue here is that
running the plug-in in this release will convert your printrc file
to the new format, which old releases cannot read.
The following printers are supported by gimp-print 4.0.0. Note that
not all of these printers can print with highest quality. In
particular, we do not have sufficient information on the Canon and HP
printers to support highest quality printing. In general, the Epson
Stylus printers all support high quality printing:

ERRATA:
1) PostScript files (and PPD's) with embedded .setpagedevice commands
to choose a media type will not function correctly. In place of
MediaType, stpMediaType will allow a choice of media type. This
will not be fixed in the release; it is not always possible to know
what media types are valid at the time of the .setpagedevice call,
which GhostScript requires.
2) The higher resolutions of the HP Deskjet 900/1220C and the HP
PhotoSmart P1000/P1100 have been disabled as they do not work.
Investigation into these modes (Photo-Ret III) is continuing. It
is possible that these resolutions will be re-enabled in a later
update to 4.0.
3) There are some known color generation problems. In particular,
greens (particularly weakly saturated greens) tend to be quite
weak, giving grass a somewhat tan look. This may be improved
somewhat by printing in 4-color rather than 6-color mode. The
errors in color are not radical, but it may be hard to get a close
match for extremely critical work.
If the image is radically too light and washed out (or radically
too dark), please check the color settings, and try setting the
defaults (1.0 for all options).
4) When using Epson 4x6 photo paper that is perforated to allow
tearing off the unprintable margins it is possible to print part
way into those margins. This will not be fixed in the release.
You must specify the correct image positioning in the plugin.
5) Red Hat 6.1 users cannot configure the plug-in. The problem is
that neither the gimp nor the gimp-devel rpm's in that release
include gimptool, which is necessary for configuration to work.
This will not be fixed in the release; it is not possible for us to
distribute a version of gimptool that will work in all cases. This
has no effect on the usability of the GhostScript or CUPS drivers.
The recommended fix is to recompile the Gimp from source (either
1.0.4 or the latest 1.1/1.2 release). That will install gimptool,
and you will then be able to build the plug-in. This does not
affect the Ghostscript driver.
6) The Epson Stylus Color 480 and 580 printers are not supported.
These printers use a somewhat different print head from all other
Epson Stylus printers that requires additional work. In addition,
these printers require a special command sequence to change the ink
cartridge (there are no front panel buttons to change the
cartridge), and that sequence is unavailable to us. We do not
anticipate supporting these printers.
EARLIER RELEASES
For users of earlier versions in the gimp-print 4.0 line (3.1 and 4.0
alpha and beta releases), the following release notes covering
specific point releases are included.
Gimp-Print 4.0.0 contains the following fixes over Gimp-Print 4.0b3:
1) All HP LaserJet printers except for the 4L are capable of 600 DPI
resolution.
2) Any residual problems with the plugin printer list containing
duplicates should now be fixed.
3) Any residual problems with scaling not being set properly in PPI
mode should now be fixed.
4) An extraneous dependency on the glibc version of getopt() in
escputil has been removed.
5) 'make clean' is now a bit more complete.
6) Certain Epson Stylus printers (the Stylus Pro XL, Stylus Color 400,
500, and 600, and Stylus Photo, Photo 700, and Photo EX) will not
print quite as close to the bottom of the paper, due to some
reports of overrunning pages. This is presumably due to paper size
or printers not being perfectly in spec.
7) Canon printers at 1440x720 DPI positioned the image too far to the
left edge of the paper.
Gimp-Print 4.0b3 contains the following fixes over Gimp-Print 4.0b2:
1) The gimp-print configure script failed on version of the Gimp older
than 1.1.20 or thereabouts, give or take a few versions. That
should now work correctly.
2) The Ghostscript and CUPS drivers did not handle printer-specific
default options correctly. This led to incorrect gamma and/or
density on many printers, and on the Epson Stylus Photo 870/1270, a
green tint.
3) Some of the defined PCL paper sizes were not included.
4) We have been unable to get the Epson Stylus Color 480 to work
correctly in any mode, due to some quirks with this printer. We
have therefore removed it from the release. It was not possible to
change the ink cartridge on this printer in any event, due to the
lack of front panel buttons and inability to get the necessary
command to change the cartridge.
5) The Canon BJC-7000 had an incorrect definition.
6) The native CUPS driver did not correctly handle the printer
resolution for non-Epson printers.
7) With CUPS 1.1.3 and earlier, the CUPS drivers do not pass through
the media type correctly, so the driver always prints with the
default media type. The solution is to upgrade to CUPS 1.1.4.
8) With CUPS 1.1.3 and earlier, Under some circumstances the margins
are not set correctly. The solution is to upgrade to CUPS 1.1.4.
Gimp-Print 4.0b2 contains the following fixes and improvements over
Gimp-Print 4.0b1:
1) The GhostScript and Foomatic drivers did not handle paper sizes
other than letter size.
2) The Foomatic drivers did not handle media type other than the
model-specific default.
3) PCL printers that do not support 600x600 in color will now fall
back correctly to 600x600 mono.
4) The print plugin crashed on startup during the second and later
invocations if scaling was set to PPI mode.
5) In PPI mode, the print plugin did not set the initial image size
correctly.
6) print-weave.c now compiles on all platforms.
7) The files 'cups/command.types' and 'cups/calibrate.ppm' are now
present.
8) The arguments to escputil have changed. Instead of -l or -o to
specify old or new series printers, the argument -m is used to
specify the actual printer model. In addition, escputil will now
attempt to autodetect the printer model for alignment purposes.
9) Print dot size at 360 DPI is now correct on the Epson Stylus Photo
720.
10) The default saturation level in Photograph mode (image type 2) has
been reduced. The new default saturation of 1.0 corresponds to a
saturation level of 0.625 previously.
11) The configure script in 4.0b1 did not function with the Gimp
1.1.26 (which was released after 4.0b1) or with certain very
recent snapshots of GNOME which may contain very new Gimp code.
12) The HP 1220C driver now supports large paper sizes.
13) The Epson Stylus Color 480 now prints. However, the driver is not
very useful, as it is not possible to change the ink cartridge
(that can only be done under software control with undocumented
commands).
14) A new paper size has been added that should be correct for Epson
4x6 photo paper (which is actually slightly larger than that, about
4.25x6.875). Note, however, that you must still position the image
correctly in the plugin in order to get a correct printout; the
margins for this special paper will not be set automatically, and
if you are not careful you may get a print too large or not placed
correctly, overrunning the perforations.
15) Newly added printers in the plugin often had their parameters set
incorrectly (most notably the gamma value, resulting in too-light
prints). That is now believed to be fixed going forward. However,
existing printers are not changed. Therefore, when you first use a
printer in the print plugin, please use the color window to check
that the parameters are set to their correct defaults (use the Set
Defaults button in the Gimp 1.1/1.2 GUI, or set all of the
parameters to 1.0 in the Gimp 1.0 GUI).
Gimp-Print 4.0b1 contains the following improvements and changes over
Gimp-Print 4.0a3:
1) For Gimp plug-in users: the format of the printrc file has changed
in a way that is incompatible with older versions of the plugin.
This version of the software can read old printrc files, but older
versions of the plugin cannot read the new format.
The new format uses a keyword-based approach that is far superior
to the old format, and will be much more amenable to future changes
that may become necessary.
2) Support for the HP Deskjet 800 series has been changed
incompatibly. The "pcl-800" driver (HP Deskjet 800 series) no
longer exists, since the 800 series printers fall into two distinct
groups, the older 850/855/870/890 printers which supported 4-level
dithering (HP calls this C-RET) at 300x300 DPI, and the newer
810/812/840/842/895 printers which do not support C-RET at 300x300
DPI (these are the same as the Deskjet 600 series).
If you are using the gimp plugin, re-select your 800 series printer
from the combo box and re-save the settings.
If you are using the Ghostscript driver, choose from one of the
pcl-8xx values detailed in Ghost/README.
If you have an 800 series printer that is not on the list, please
try both the old C-RET driver (choose model 890) and the non C-RET
driver (choose model 895) and see which one works at 300x300 dpi.
Also, please let us know; the address is in the README file.
3) The HP Deskjet 1220C has been grouped with the 900 series.
4) The HP PhotoSmart P1000 and P1100 have been added, they are like
the HP 900 series.
5) Online documentation for the print plugin finally exists.
6) Support for CUPS, through a choice of a native CUPS driver or
Cups-o-Matic.
7) Support for the Foomatic printer configuration system, greatly
simplifying configuration and use with lpd, CUPS, and PDQ.
8) The preview window in the plugin now shows a low-resolution
representation of the actual image. The color adjustment window
shows an thumbnail that reflects the effect that color adjustments
have on the output.
9) The old GTK-based interface is now disabled by default when used
with the Gimp 1.1. It can be enabled by running configure with
--enable-maintainer-mode.
10) The plugin now detects the spooling system at runtime, so it need
not be compiled specifically for use with Berkeley lpd, System V
lp, CUPS, or LPRng.
11) Substantial quality improvement for many Epson Stylus printers in
in 1440x720 DPI modes. The price is that printing takes much
longer. If you need high quality with better performance, use
720x720 DPI Highest Quality.
The specific printers that are affected are the Epson Stylus Color
600, 800, 850, 900, 1520, and 3000, and the Epson Stylus Photo 700
and EX. The effect in all cases will be smoother output that is
particularly visible in pale tones.
12) The Fast dither algorithm has been slightly tweaked, and a Very
Fast dither algorithm has been added.
13) Most menus have been converted to combo boxes.
14) The printrc code has been fixed to set reasonable defaults if an
old printrc file with now-invalid parameter settings is read.
15) It is now possible to print in seascape and upside down portrait
mode.
16) The support for the Stylus Photo 2000P has been fixed and should
now be correct.
17) Printer names may now be up to 127 characters.
18) Additional performance improvements over earlier versions of this
package.
19) A number of miscellaneous bugs have been fixed.
Gimp-Print 4.0a3 contains the following improvements over Gimp-Print
4.0a2:
1) The brightness, contrast, and color level controls have changed
incompatibly in both the plugin and the Ghostscript driver. The
controls now adjust cyan, magenta, and yellow levels. In addition,
all controls are now arbitrary values centered around 1, rather
than some being centered around 1 and some being integer values
centered around 100.
Furthermore, the action of the color level controls is now much
more what would be expected. The cyan, magenta, and yellow
controls can be used to balance the printer grayscale.
Plug-in users: please be sure to check the color values in the
Adjust Color window before printing or reporting a problem. Use
the Set Defaults button to bring them back to reasonable defaults.
Ghostscript users: please see the Color Balancing Values section of
Ghost/README for details.
2) The MediaSource argument in the Ghostscript driver has been renamed
InputSlot, to conform to the PPD standard. Therefore, any
uses of Ghostscript that use this argument must change.
3) There is a new Fast dither algorithm. This produces greatly
improved speed at some cost in image quality. It gives poor
results on 6-color printers when used in 6-color mode. In black
and white mode, the results are generally quite acceptable.
4) Performance has been improved to some degree in all modes. This
will probably be most noticeable when printing text, and when
printing at a higher resolution than the source image is sampled at.
5) Density is now computed correctly in 1440x720 mode on Canon
printers.
6) Positioning should now be correct on the Epson Stylus Color 850 and
similar printers.
7) The inlining problems with egcs 1.1.2 are now fixed properly, so
inlining is re-enabled.
8) The problem with blank splotches is now fixed. It was closely
related to the other inlining problems (which weren't really
inlining problems at all).
9) Ink densities and other color parameters have been tuned for
additional paper types. In particular, plain paper and generic ink
jet paper should now work reasonably well.
10) Monochrome mode prints with correct density on variable dot size
printers (it was printing too light or entirely incorrectly).
11) The Gimp-based GUI (usable only with Gimp 1.1.22+) has been
extensively reorganized.
12) Monochrome (fast black-only) mode works correctly on variable dot
size printers.
13) HP printers with multiple input sources now print correctly by
default (using the standard paper source rather than the manual
feed).
14) Bug fixes to the Canon driver for certain printers.
15) Preliminary support for the Epson Stylus Photo 2000P, Stylus Color
880, and Stylus Color 980. The 880 and 980 should work reasonably
well. The 2000P has not been tuned.
16) Performance and print quality on the Epson Stylus Color 900 is
improved.
17) There have been some miscellaneous improvements (or at least
changes) in color generation.
18) Images will now print to their exact specified size. In previous
versions, if percentage scaling was used, the scale was effectively
rounded down to the next percentage point.
19) The height/width entries are more accurate, and do not
automatically set the scaling mode to PPI.
20) Preliminary support for the Epson Stylus Color 880 and 980
printers.
21) Miscellaneous bug fixes for certain Epson Stylus printers.
Gimp-Print 4.0a2 contains the following improvements over Gimp-Print
4.0a1:
1) A serious bug in the handling of landscape mode (in the plugin
only) has been fixed.
2) A new 360 dpi softweave mode has been added to the Epson driver for
the variable drop size printers, which should yield improved
quality. It is reasonably well tuned on the 870.
3) Improved tonal smoothness in highly saturated red, green, and blue.
4) The Ghostscript driver produces more useful error messages if
incorrect parameters are supplied.
5) The top margin of the Epson Stylus Color 850 should be correct
now. The printer is not capable of printing to the top of the
page.
6) Ink levels have been fine tuned (not necessarily correctly) for
newer Epson printers.
7) Work around some inlining problems with egcs 1.1.2.
Gimp-Print 4.0a1 contains the following improvements over Gimp-Print 3.1.9:
1) The Ghostscript driver has been extensively revised. IN
PARTICULAR, THE OPTIONS HAVE CHANGED TO A DEGREE MAKING IT
IMPOSSIBLE FOR ANY USES OF THE OLD DRIVER FROM WORKING WITH THE NEW
ONE. Please read Ghost/README for a full explanation of the new
options.
2) The Ghostscript driver now supports all printers supported by the
Gimp plug-in, including PCL and Canon printers in addition to Epson
Stylus inkjets.
3) Photo mode has had major improvements in its color generation in
corner cases. It is slower than it used to be, unfortunately.
4) The inks have been retuned for 6-color Epson printers; they should
now better match those of 4-color printers.
5) It is now possible to print to the very edge of the top, left, and
right on Epson Stylus 870 and 1270 printers.
6) An experimental CUPS driver is now in place in the Cups
subdirectory. It is not based on the current source base. It will
be redone before 4.0 release.
7) Printing near the top and bottom of the paper is substantially
improved on Epson Stylus printers.
8) Printing on PCL printers is fixed.
9) Epson Stylus printers have more flexible tuning than previously,
allowing specification of smaller dot sizes in some cases, which
will yield better output quality.
10) Ghostscript driver bug whereby only half the page was printed in
certain resolutions is now fixed.
11) Adaptive hybrid dithering is now the default.
Gimp-Print 3.1.9 contains the following improvements over Gimp-Print 3.1.8:
1) A bug in the GhostScript driver would cause the driver to go into
an infinite loop on some systems with some printers, depending upon
details of the compiler and so forth. All users of the GhostScript
driver should immediately update.
2) Substantial quality improvements across many printers:
* Output across printers and resolution modes is much more closely
matched (except probably 360 DPI). The saturation may be
somewhat less than before, however.
* 720 DPI is greatly improved on Epson Stylus Color 860/1160 and
Stylus Photo 870/1270. The 750/1200 may not show this
improvement.
* Artifacts in the adaptive hybrid and adaptive random dithering
modes have been eliminated.
Gimp-Print 3.1.8 contains the following improvements over 3.1.7:
1) The entries for printer model and paper size have been greatly
improved. There are many additional paper sizes offered.
2) Print quality using adaptive, hybrid, and ordered modes is improved
at 1440x720 DPI.
3) The UI now offers a choice of metric or English units for
measurements.
4) The print preview is much larger, affording easier viewing of the
placement of the image. An arrow is used to indicate the top of
the paper, and the size of the arrow gives an indication of the
actual paper size.
5) It is now possible to specify the output width or height directly.
6) Dragging the preview image with a button other than the left moves
the image in units of points rather than screen pixels, affording
finer placement control.
7) A new emulated 1440x2880 mode has been added for highest quality
printing on Epson Stylus printers. It is of most use on the Stylus
Photo 750, 1200, 870, and 1270.
8) Experimental improvements for the Canon BJC-8200.
9) The plug-in should operate correctly with the plp spooling system.
10) Support for the Epson Stylus Photo 720 and Stylus Color 480. Also
correct the Stylus Color 860 and 1160 entries.
11) Support for the HP 540C printer.
12) Correct treatment of saturation adjustment, and allow saturation
of 0. This allows printing a color image in black and white using
color inks for maximum smoothness.
13) Allow choice of four and six color printing on six color
printers. This is useful for economy (normal printing uses much
more light cyan and magenta than dark), and may improve saturation
for graphics.
14) Bug fixes for Ghostscript driver. Also, Ghostscript driver now
offers choice of ink type.
15) Some improvement in Epson Stylus Photo, Photo 700, and Photo EX
output quality.
Gimp-Print 3.1.7 contains the following improvements over Gimp-Print 3.1.6:
1) Emergency GhostScript bug fix.
2) escputil program now retrieves ink level from the printer.
Gimp-Print 3.1.6 contains the following improvements over Gimp-Print 3.1.5:
1) Print speed has been greatly improved for sparse pages. This will
not help too much for images, but it will help greatly for text and
other typical PostScript printing.
2) 3.1.5 turned out not to improve print quality over 3.1.4; in fact,
there was some regression. There has been some improvement over
3.1.5, particularly for higher end printers. 1440x720 enhanced
mode (which is computed as 1440x1440) using adaptive hybrid or
adaptive random dithering appears to work best.
3) Microweave and 360 dpi positioning is now correct.
4) The Lexmark 4076 is now supported (as a PCL printer).
5) The preview window now notes the size of the image in addition to
the position.
6) The code now uses much less memory at high quality settings.
7) Perturbed ordered dithering has been removed.
8) An experimental program to perform nozzle check, head cleaning, and
head alignment is now included. This is potentially dangerous, so
read the accompanying help information carefully before performing
head alignment!
9) The Ghostscript driver now correctly handles -r1440x720.
10) The PDQ support has been updated, and a CUPS .ppd file added
(these are not tested).
Gimp-Print 3.1.5 contains the following improvements over Gimp-Print 3.1.4:
1) Greatly improved print quality. In particular, ordered dithering
and adaptive dithering methods are now much better than ever
before. We recommend ordered dithering for four-color printers and
either adaptive hybrid or adaptive random dithering for six-color
printers.
2) If a print job is canceled from within the Gimp, the partial file
will not be sent to the printer.
3) Support for additional Canon and Hewlett-Packard printers.
4) Epson Stylus printers can now print much closer to the edge of the
page. They can print to the extreme top edge and much closer to
the bottom than before, although there is some loss in quality
close to the edge.
5) Greatly improved black quality.
6) The preview window now shows the borders of the printable area in
addition to the borders of the page. In addition, the offsets are
now from the true edge of the page rather than from the edge of the
printable area.
7) 720 dpi highest quality and 1440x720 dpi highest quality are now
supported on the new generation Epson printers.
8) Epson printers will now print faster on sparse pages and in pure
black and white. This is of particular interest for the
Ghostscript driver.
Gimp-Print 3.1.4 contains the following improvements over Gimp-Print 3.1.3:
1) Support for the Hewlett-Packard DeskJet 960.
2) Print quality improvements.
3) Some print speed optimizations.
4) Major fix for hybrid Floyd-Steinberg dithering
Gimp-Print 3.1.3 contains the following improvements over Gimp-Print 3.1.2:
1) Completely revamped dithering algorithms. These algorithms should
be faster and easier to maintain in addition to better,
particularly on more advanced printers. There are additional
choices for dithering algorithms: an ordered dither, and two kinds
of Floyd-Steinberg error diffusion. There are also adaptive error
diffusion algorithms, in which ordered dithering is used in certain
circumstances.
2) The user interface has been heavily revamped. There are currently
two options, one based on the Gimp native toolkit and one based on
GTK. Depending upon user feedback, one will be withdrawn at some
point.
4) Support for additional Hewlett-Packard printers and media.
3) Bug fixes for Epson printers, the GhostScript driver, and many
other things.
Gimp-Print 3.1.2 contains the following improvements over Gimp-Print 3.1.1:
1) Better dither quality.
2) Dither is optimized for several different types of images
(photographs, continuous-tone images such as charts, line art, and
very fast pure black/white rendering).
3) Tweaking of the GhostScript driver.
4) Epson Stylus Color 440 prints in softweave. In general, most Epson
printers are more reliable.
5) Preliminary support for more Hewlett-Packard printers.
Gimp-Print 3.1.1 contains the following improvements over Gimp-Print 3.1.0:
1) Faster dithering speed.
2) Improved support for many Epson Stylus printers.
3) Some UI improvements.
4) Numerous bug fixes.
Gimp-Print 3.1.0 contains the following user-visible improvements over
Gimp-Print 3.0.5, the version distributed with the Gimp 1.1.17:
1) Preliminary support for Canon BubbleJet printers (specifically the
BJC6000).
2) Preliminary support for the Epson Stylus Color 440/640/740/900 and
Stylus Photo 750/1200 printers. These printers should in theory
work in all modes, although that has not been comprehensively
tested. 1440 dpi mode on the 900 in particular may not work.
There is also pre-preliminary support for the Stylus Photo 870 and
1270 based on the published specifications. This driver is
completely untuned for these printers at present.
3) Ability to position the image on the page to the point (1/72", or
about .35 mm), along with a more accurate depiction of the
positioning on the page.
4) One-click ability to scale to the image resolution (Gimp 1.1 only).
5) Much better handling of the saved state (printrc file), including
saving of parameters related to file output.
6) Utilities (in various states of completion) to reconstitute an
image from a print file.
7) Bug fixes for density in indexed and gray modes, and for excess
pseudo-black printing in general.
There are additional improvements over Print 2.0.2 (the version
distributed with Gimp 1.1.11 and earlier) too numerous to list here.
