[opensuse] HP LJ 2015x problem selecting tray

Hello everybody. I have a problem with my HP LaserJet 2015x (2015 with 3rd tray, duplex unit and network) printer: whatever I say to driver, it always takes paper from tray 2. OS is openSuse 10.3 (same was with 10.2). I have tried setting different types of paper in printer and in driver, different sizes (although I only use A4), but with no effect. On test page I see which tray was selected by driver, but printer just ignores it. Best regards, Siniša Bandin
