Comment 7 for bug 172813

I have an Apple iBook G4 PPC connected through USB to an HP Deskjet 5650W printer which has worked for quite a while. Recently I upgraded from Feisty Fawn (7.04) to Gutsy Gibbon (7.10) and then on to Hardy Heron (8.04). (I have kept it up-to-date as of a couple hours ago.) In Hardy Heron I see a problem with printing that I didn't see in Feisty Fawn which is described in /var/log/cups/error.log as:

So I searched for '%%BoundingBox' issues on Launchpad and read the advice above concerning A
ppArmor.

rwilbur@transform:~$ sudo aa-complain cupsd
Setting /etc/apparmor.d/usr.sbin.cupsd to complain mode.

I connected to the printer and tried again with the following

rwilbur@transform:/var/log$ sudo tail messages

The audit entry looks remarkably similar to Tom's above, even though I have a local printer!
