Hi Laurence, I still have doubt about PPD. Does PPD only describe the attribute of printers? Does it do any work with PostScript? If I have a non-PostScript printer which supported by HPLIP, how can I configure it to print out PostScript? Do I only need to install HPLIP or anything else (install PPD, configure CUPS etc.)? Thank you very much for your reply. Best regards, Leon __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
