I had a working printer Canon imageRunner 8500 until Gutsy. I've deleted and recreated the printer several different ways, I've edited /etc/apparmor.d/usr.sbin.cupsd as suggested, I've done the "aa-complain cupsd". None of these worked for me. Stopping apparmor still leaves the problem. Here's a brief history.
$ /etc/init.d/apparmor status

0 processes are unconfined but have a profile defined.
