You then need to setup CUPS to define and configure the printer, giving it the printer address, the PPD file to use etc. The installation is set out in the HPLIP pages on sourceforge. > > Thank you very much for your reply. > > > Best regards, > Leon > > __________________________________________________ > Do You Yahoo!? > Tired of spam?
