How to Choose a PPD File for a PostScript Printer
Choosing a PPD file
PostScript printers may use PPD files to give you access to special printer features. Mac OS X assigns a PPD file to a USB or AppleTalk printer automatically when you add the printer. You manually select a PPD file when adding an LPR printer to the printer list. Even if a PPD file is not found for a given LPR printer, Mac OS X can still print to it. Choose the Generic PPD or one for a printer model similar to yours. Choosing a similar model often provides access to more of your printer’s capabilities the Generic PPD does, which is designed for maximum compatibility with a wide range of printers.
