Hi Helge, Thanks for your suggestions. I have tried setting tray 2 as being installed (both with the radio button on the web page and with lpadmin; lpadmin -p hp1320-parkstone -o HPOption_Tray2=True; lpadmin -p hp1320-parkstone -o InputSlot=Tray2) but this has not worked. Do you have any more suggestions? Thanks. Paul
