Package: python-foomatic
Severity: normal
Hi
detect_usb_printers() in detect.py fails to detect the USB printer, if
it doesn't exist on /dev/usb/lp0 . If I have two USB printers attached
and then remove the first one, udev removes /dev/usb/lp0, but keeps
/dev/usb/lp1 for the second one. The attached patch checks for such
cases and tries to specify the first lp device it finds.
Please consider including it into detect.py.
Cheers
Steffen
