How does one get PUP to work. When I first opened it the 'output' was: /dev/lp0 and the Printer was: Lexmark Optra 40/45. Neither is correct for me. I have a Printer: HP 3940 and it is located at /dev/usb/lp0. I opened PUP in root and was able to change 'output' to /dev/usb/lp0 but the drop down list for printers only contains 5 options unfortunately none close to my needs. Can anyone help me with this???

Of what use is a printer utility if it only works with 5 models of printers??? I must be missing something, Time to Google.
