Both printconf and foomatic-gui do not work correctly with current Foomatic any more. They show many printer/driver pairs for which Foomatic cannot provide a PPD file because either the driver XML file has no or an empty command line prototype or the driver XML file does not exist and the printer XML file has no link for a ready-made PPD which exists on the current system. This is an upstream bug.
