However, when I add a printer using the Cups web interface, after I click on "HP" for "Make", I am only presented with 4 items for "Model": "HP DeskJet Series CUPS v1.1 (en)", "HP LaserJet Series CUPS v1.1 (en)", which appears twice, and "HP New DeskJet Series CUPS v1.1 (en)".  This doesn't sound like what I should be getting.  Any suggestions as to what's wrong?
