>Description:
Since the update from CUPS 1.1.23_9 to 1.2.0_2, my printer stopped working. 

The following error is mentionned on the "Printers" page on the web administration page :
"Unable to open USB device "usb:/dev/ulpt0": Permission denied"

Restarting the printer (both physically and from the driver) has no effects.

Changing the printer driver (from a Generic PCL 5e Printer Foomatic/ljet4 to a Lexmark Optra E321 Foomatic/ljet4) has no effects.

This problem could be platform independant (see http://www.fedoraforum.org/forum/showthread.php?t=109680).

Printer is a Lexmark E232 (worked 100% with Cups 1.1.23_9 and previous versions).
>How-To-Repeat:

>Fix:
Suggest a move back to CUPS 1.1.23_9.
