Assigning to Martin Pitt, as requested. Let me know if there is any more information I can provide, or experiments I can do to help debug this.
Further, here are the symptoms that I see from cupsd when I try to print (with the /etc/apparmor.d/usr.sbin.cupsd in place): Upon requesting a test-page from the printer properties panel, I get an error dialog box with the following message:
Print Error
There was a problem sending document 'Test Page' (job 12)
to the printer. The printer called `pd201` has been disabled.
[Diagnose] [OK]
Further, the printer state in cups switches to "Stopped -- Unable to locate printer 'printserver.example.com'!
Also note that this seems only to effect lpd printing so far. I am able to print to my samba shared server at home.
