I looked at the installed drivers and saw that I had different ones for device HP5000 and HP5000onepage. Only the "onepage" driver had trouble. This one had a driver of "HP LaserJet 5000 Series Postscript (recommended)", when I switched to "HP LaserJet 5000 hpijs, 3.10.2" it worked again.
Furthermore the driver "HP LaserJet 5000 Series Postscript (recommended)" is not even available any more for me, so it seems to have been caused by an outdated printer driver. Not sure if it makes sense to further investigate, therefore I am closing this for now. ** Changed in: cups (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738438 Title: Printing PDF document sometimes does not work, printer states "processing job" endlessly, HP Laserjet 5000N -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
