Problems with color printing on Laserjet 2600n

The problem of needing to add the "-c" in the PPD file is an upstream bug. I will report it to the author of the foo2hp driver (part of the foo2zjs package).

The problems with color accuracy can be cause by GhostScript. Try to install the gs-gpl package and then run

sudo update-alternatives --config gs

and choose "gs-gpl". Are the colors better now?

Yeah; the quality still sucks, but the colors are a lot better.

You do not need to edit the PPD file to change the color mode. You only need to change the default setting of the "Color Mode" option. To do so, right-click the printer icon in the gnome-cups-manager and choose "Properties". On the "Advanced" tab you can set "Color Mode" to "Color". To get a better output quality try also to set "Bits per Plane" to "2 Bits per Plane".

If these changes have no effect, call the CUPS web interface via http://localhost:631/, click the "Printers" tab and click "Set printer options" at the entry for your printer. Set the above-mentioned options there and try again.

Does it work now?

Yeah, on three different boxes doing it via "gnome-cups-manager" didn't
work; I never tried the web interface though. I'll try changing the
file back and using that to fix it when I get home. Note that the
forums contain reports from other people that it doesn't work, and lots
of non-Ubuntu forums talk about it too, always with either editing the
file or not using Ubuntu's foo packages at all as the solution. See the
links I provided.

Also tried setting Bits per Plane to 2, and that just causes printing to
silently fail. Setting it back causes printing to begin working again.
I was going to file that as seperate bug this weekend.

The author of foo2zjs tells that this is a problem of GhostScript and you should use the newest version.

Download the files from

http://www.linux-foundation.org/~till/tmp/ubuntu/gutsy/ghostscript/

into the same directory. Then do

sudo apt-get install build-essential fakeroot
sudo apt-get build-dep gs-esp gs-gpl
dpkg-source -x ghostscript_8.60.dfsg.2-0ubuntu1.dsc
cd ghostscript-8.60.dfsg.1
dpkg-buildpackage -rfakeroot
cd ..
sudo dpkg -i *gs-esp*.deb *gs-afpl*.deb *gs-gpl*.deb *libgs*.deb *ghostscript*.deb

and you will have the latest Ghostscript.

Answer every question which appears with "y", so that all needed packages get installed.

Please tell us your results with the test packages.

Bug 106003 is a similar problem and can be a duplicate of this one.
