This most likely is the wrong component for this, but I'm sure you know the right one :) I've been setting up a hP laserjet 4000 printer (over smb) today and that defaults to sending postscript directly to the printer. However the printer stopped printing the first page with a picture of the first pdf I printed, so I decided to change the driver to FOOMAGIC - plxmono. This is not the real bug, just background info, this problem could be very likely outside of Fedora's control (we use page accounting on the printserver, maybe that choked on the picture, or may the PS interpreter in the printer itself or .....). Although I'm concidering filing a bug that all postscript capable printers or atleast HP postscript printers should default to the best native (PCL in case of HP) driver instead of to default. Sofar I've never had any luck with HP postscript printers and I've always changed to a PCL driver with much better results. Let me know if you want this as a bug. Ok after this long intro now the real bug then. As said I changed the driver for this printer (HP lj 4000) from the default PS to Foomatic - plxmono, after this system-config-printer printed the following to the terminal it was started from: foomatic:HP-LaserJet_4000-pxlmono.ppd foomatic:HP-LaserJet_4000-pxlmono.ppd PPD name: foomatic:HP-LaserJet_4000-pxlmono.ppd Cups PPD Media Source unknown value: Middle And after applying the changes it turned out that the Media Source was set to Manual Feeder, which wasn't what I wanted :) I'm thinking that maybe the component shouldn't be changed after all, but instead this bug should be filed twice: 1) If the Media Source is unknown, it should default to Printer Default, not to Manual Feeder (that would be this bug then) 2) The mentioned PPD needs fixing, this is for another component I assume (that would be a new bug needing filing then). Let me know if you agree with splitting this bug and which component is correct for the PPD issue and I'll file a new bug for the PPD issue.
This all comes down to a CUPS bug, which I've now reported upstream: http://cups.org/str.php?L1929
