[Lilux-help] SuSE & HP Printer

Hi, my brother-in-law has as new installation of SuSE 9.3, with current online updates (via YOU), on a classic x86 system. His printer is an HP PSC 2110 all-in-one device. Scanning works fine, no trouble there, but I can't seem to get printing to work (it did fine with the older 8.3 installation). The device is detected automatically by YaST, as psc2100series, HP PSC 2110, PPD file HP PSC 2110 Foomatic/hpijs, connection HP All-in-One Device /usb/PSC_2100_Series I tried both the hpijs and gimp-print PPDs, no success. I'd have tried configuration or at least more testing via CUPS in http://localhost:631, but unlike Debian GNU/Linux systems, this one doesn't take the root / rootpassword as authentication. Any ideas on what to try? Greetings & TIA, Eric
