I've posted this on Apple's forums as well. I've had a Canon Pixma 4000r which has printed wirelessly with no problems for over a year. We've got several iBooks, an iMac and a PB G4 all of which worked fine. Now, it suddenly won't process jobs. Just quit out of the blue, unrelated to any software or system changes.
Works fine if directly connected via USB.
Tried:
Downloaded new drivers, deleted prefs, deleted receipts, reinstalled, reloaded network settings, repaired permissions, ran onyx. etc.
CUPS page says it's online, but won't print test page.
cups error log says:
Error 306 as well as:
I [25/Nov/2006:06:46:27 -0600] Printer 'iP4000R__00_00_85_5b_4a_0e_' stopped by ''.
E [25/Nov/2006:06:46:27 -0600] release_job: job #137 is not held!
E [25/Nov/2006:06:46:27 -0600] PID 303 stopped with status 85!
Moved my Airport express into the room with the printer. Prints fine with Bonjour but now my express isn't hooked to me audio system anymore.
Any ideas? I have no idea what error 306 is or status85.
