How do I install and use a PPD file?
To install a PPD file, copy it to the System Folder > Extensions > Printer Descriptions folder.
To use a PPD file, print using a PostScript printer driver, such as the Adobe PostScript printer driver called AdobePS. If you do not have a PostScript printer driver, you must install and configure it before you can use it for printing.
AdobePS is available for free from the Adobe Web site at: www.adobe.com/support/downloads/main.html in the Printer Drivers section.
Some applications may require the PPD file to be copied to an additional location. See your application's documentation to determine if your application searches for PPD files in a specific directory. If you have any such applications, use the Finder to copy the PPD file to the location(s) that your applications require.
