I'm sorry to report that I'm experiencing this on Ubuntu 12.04 with CUPS 1.5.3 printing to a Canon MP160. This setup used to work perfectly before upgrading from 10.04.
If I run `sudo aa-complain cupsd`, then I can print multiple documents. As soon as I revert by running `sudo aa-enforce cupsd`, then I can only print one job and then printing halts. Actually, even with apparmor disabled, there are issues if I try to print from different computers.
I'm attaching output from /var/log/cups/error_log and from grep audit /var/log/syslog

Let me know if I can provide any more info.
