Obvious info: The problem is not fixed by deleting and recreating the printer in system-config-printer. $ rpm -qa|grep cups|sort cups-1.5.4-2.fc17.x86_64 cups-libs-1.5.4-2.fc17.i686 cups-libs-1.5.4-2.fc17.x86_64 cups-pk-helper-0.2.2-1.fc17.x86_64 ghostscript-cups-9.05-1.fc17.x86_64 libgnomecups-0.2.3-11.fc17.x86_64 python-cups-1.9.61-2.fc17.x86_64 I've just found that the system-config-print 'print test page' works. But not printing from any other application I tried. So this might be a problem with the cairo (?) printing rather than cups? Experimenting futher: Printing from firefox does not work. Printing PDFs from evince does work. Printing a .ps file (generated by GEDA pcb) from evince does work. So looks like a problem at the rendering level rather than the printer spooler level. Re-assigning to cairo, as my best guess of the most likely culprit. Resetting assignee. Ok, I tracked down the problem a bit:
The print supports only postscript level 2. This is appears to be noted in the foomatic XML file /usr/share/foomatic/db/source/printer/HP-LaserJet_4000.xml:
<lang>
<postscript level="2" />
But foomatic ignores this when generating the ppdfile and sets the postscipt level to 3 (observced both with setting up the printer via the GUI and running foomatic-ppdfile by hand):
$ foomatic-ppdfile cat foomatic-ppdfile:HP-LaserJet_4000-Postscript.ppd
...
*LanguageLevel: "3"
...
Editing the ppd file by hand gets the printer working again, printing a pdf from evince.

Well done, I'll take a look at it. I've just found this note on http://en.gentoo-wiki.com/wiki/CUPS Seems many HP Printers have problems printing Postscript Level 3, such as rectangle glyphs replacing chars even with their binary drivers installed. When you configure your HP printer, or to resolve this issue, edit the printer's PPD file and set '*LanguageLevel: "2"'. Upon further research, only Postscript Level 2 is accepted by HP printers! Even though you might think you're printing PS Level 3, you're final file is likely PS Level 2. Both MS Windows and Ubuntu are hard-coded to only print PS Level 2, even when PS 3 has been specified/selected! My Perl-fu is too poor to make some conclusion, but it seems that LanguageLevel: is indeed always set to "3". The generateppd() in foomatic-ppdfile calls getppd() from /usr/share/perl5/vendor_perl/Foomatic/DB.pm which takes (with get_tmpl()) a template PPD (containing *LanguageLevel: "3") and substitutes various statements, but LanguageLevel is not substituted. Needs reporting upstream: https://bugs.linuxfoundation.org/ This message is a reminder that Fedora 17 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 17. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '17'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 17's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 17 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 17's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
