http://askubuntu.com – Attempting to fix my church's computer... Ubuntu 11.04 operating system.. hp 8600 printer. The printer was working perfect, until they had a power outage. When attempting to print they would get a cups error. I got the system past this issue...now when selecting print, the computer goes through entire print process, and window pops up saying print successful, however nothing went to the printer. Power to printer is on, with all power save options turned off during testing. All USB plugs are connected, and printer does print its own settings page out, just wont print anything sent from the comp (HowTos)
