i recently updated from 10.04 to 12.04 and can no longer print. i've spent the last three hours browsing/troubleshooting, but nothing is working.

i've followed about a half dozen strategies for solving this, and would appreciate any help. i know its impossible for you guys to help without details, but i'm not sure what info to give or where to find it.

i have reinstalled cups. when i tried to reinstall the hp driver the wizard didn't seem able to find the printer. when i open the "job attributes" window, the "job-printer-state-message" says "/usr/lib/cups/backend/hp failed".
