Bug#370817: Not only usb printers

[Tobias Frost <tobi@coldtobi.de>]

severity 370817 grave
thanks

(Please appologize the severity, but I think it is not a good idea to
let this pacakge in testing without resolving this issue)

Also my printer (Espon Stylus 640) stopped working. 
There is no error message in the logs.
(Just "backend failed with status 1")

I did not change the configuration.

Adding the printer also failed, it is mis-detected as both CANON and
EPSON on the same parallel port.

However, even if adding the printer with manually selecting the ppd
file, this won't help....
