If my instructions of comment #15 do not lead to the solution of this problem, try the following:
sudo dpkg -P --force-depends system-config-printer-udev Then turn off and turn on your printer and test again several jobs. Is printing working all the time now? If not, return to the old state via sudo apt-get install -f system-config-printer-udev Then try sudo chmod -x /usr/lib/cups/backend/hp sudo chmod -x /usr/lib/cups/backend/hpfax Now turn off and turn on your printer again and test again several jobs. Is printing working for all jobs now? If not, return to the original state via sudo chmod +x /usr/lib/cups/backend/hp sudo chmod +x /usr/lib/cups/backend/hpfax Also try to boot a live CD of Ubuntu 12.10 (beta1). Does printing work correctly then? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1045718 Title: [Xerox Phaser 3155] Requires USB unplug & replug every few minutes Status in “cups” package in Ubuntu: Incomplete Bug description: My printer requires me to unplug and replug it into the system once in a short while. This is because otherwise it doesn't print. Jobs get accepted or processed but not printed actually.
