Comment 7 for bug 147800

I've got the same problem here. Bluetooth printing to HP Deskjet 995C was working fine earlier in the Gutsy release cycle but tonight I find it can't print and the reason appears to be related to the appamor configuration in /etc/appamor.d/usr.sbin.cupsd since disabling appamor (sudo /etc/init.d/appamor stop) allows the printing to go ahead.
