Hi,

i've bought a Phaser 6110 and planned to have it connected to my Ubuntu box allowing my wife to print to it from her Intel MacPro & my daughter from her XP machine.

Following the install on Ubuntu using the supplied driver the quality of print was extremely poor so I tried changing to foo2zjz. Though this gave more options the quality did not change.

The printer is now connected by USB to my wife's Mac and the print quality is fine. I've added the printer to my Ubuntu Cups using the foo2zjs driver and get the following:

1) If I print a page from Ubuntu which is mixed colour/black with the printer set to monochrome in the Ubuntu CUPS then all is well.

2) If I then change the printer to colour in CUPS and reprint the same page the black text is extremely poorly defined and blurry. However other colour text on the same page (e.g. blue) is much sharper (though I'm not 100% sure its as sharp as it should be!)

3) Printing a similar page from the mac is no problem in either monochrome or colour.

4) Printing from an X11 app on the Mac also results in the blurred text syndrome!


Any suggestions on how to troubleshoot this greatly appreciated!

        * foo2qpdl-wrapper: fix it again.  NOTE: use only gs 7.07 OR gs 8.54+
        to print color!!!!  Ubuntu has a problem with gs 8.15!!!

        * foo2qpdl-wrapper: Fix gamma for black text (black-text.ps).
            For Samsung CLP-300/600, CLX-3160, Xerox Phaser 6110/6115MFP.

I'm now running GS 8.54 and the latest driver (as of an hour ago) and there is a significant improvement - thankyou!


However the text is still far from sharp. Are there any other things I can try or is this the best available for this printer at the moment?

I have some time available to help troubleshoot this if that helps?

Best available.

Hi,

I bought Xerox Phaser 6110 and had the same problem like Dom's - the colors were very dark and the general quality of the color output was very low. Turned out the culprit was ... foo2zjs-icc2ps, which segfaulted inside the foo2qpdl-wrapper script (funnily, it worked fine when run manually at the shell prompt). Here is the patch - viva valgrind:

(NB: my box is 64bits). After the fix, everything is fine - thanks for the driver!
