I had this problem with current Ubuntu version (10.10). After some update, the printer, that is a Lexmark with the driver provided by the manufacturer, stopped working. I found this bug and after using the suggest command
sudo aa-complain cupsd ^^^
The printer started working again.
So I think there is still a bug, or a new one, as long as I should not be obligated to do such command (luckily I found it).
Bellow the dmesg output, with the first lines showing the situation before the aa-complain and the last ones with successful printing, after the command.
I can provide additional information if it's necessary.
