Hello, thank you Henry Jensen for your suggestion. I have renamed /usr/lib/cups/filters/pstops to pstops.lenny and copied the pstops from an etch machine to the updated lenny server as pstops.etch. Then made a symbolic link for pstops.etch -> pstops Now everything works fine, and the users can select if they want to use duplex or not, toner saving or not. Attila Mesterhazy
