Not for me.

This is on a box that was recently upgraded from feisty, and the printer was working perfectly.
No difference between gnome interface or web localhost:631(?)

Printer doesn't get detected by 'add new printer'

After manually choosing port and printer details, printer immediately moves all jobs to "Stopped"

Same problem happens for every printer I have available, PPT or USB.

sudo aa-complain cupsd has made the problem go away, for now at least.

Let me know if you want any more details.
