As for executing the files in /usr/lib/cups/backend:
hp returns information on the attached USB printer

quote

direct hp:/usb/photosmart_1215?serial=MY1CM851WJ0U "HP photosmart 1215" "HP
photosmart 1215 USB MY1CM851WJ0U HPLIP" "MFG:HP;MDL:photosmart
1215;CLS:PRINTER;DES:photosmart 1215;SN:MY1CM851WJ0U;"

End quote

but all others return either no output at all or "Unknown" and the protocol
descriptor.

Thank you Ron Morse
