When I click on the add button, a screen comes up for me to select a printer device. It has the choices: "Generic CUPS-PDF Printer," "Other," and "Network Printer." Under "Network Printer," it has "Find Network Printer," "Apsocket/HP Jet Direct," and "Internet Printing Protocol." The little wheel at the bottom turns while it searches for the printer device, and when nothing is found, it stops. The only printer that has a URI shown is the "Generic CUPS-PDF Printer and that URI is cups-pdf:/. When I am running the LiveCD, it finds my DeskJet 722c with no problem.
