Problem is that the USB CUPS backend cannot cope with printers which do
not supply a device ID. Real USB printers always supply a device ID, but

Workaround for the time being is entering the URI
parallel:/dev/usb/lp0 for USB-Parallel adapter cables and not using
more than one of these cables and no additional real USB printers on one
computer.

This most probably prevents your system from reporting the printer
correctly to system-config-printer and so system-config-printer does not
