Printer outputs an extra sheet after every printjob

Hi SuSE 8.0, "out-of-the-box" installation, printer is HP DeskJet 900-series. After every printjob, the printer will feed an extra empty sheet of paper. Printer was set up with zast2, and it is connected locally to lp0. From LAN clients (both M$ and Linux) this happens, also when printing from that computer console. I have tried to look from /etc/printcap for ajdustment, but no luck there. Where should I look for this?? Jaska.
