POSTSCRIPT

PostScript printer description (PPD) files

PostScript printer description files (PPD files) are readable text files that provide information about the special features of your printing device to the application program running on your host system. PPD files include information about page sizes, finishing features, and fonts, among other items.

PPD files are stored on a client workstation or PC where they can be parsed by applications. Some application programs supply PPD files for a variety of printers, rather than have you contact printer manufacturers to obtain one.

The DocuPrint PPD files provided with DocuPrint software conform to version 4.2 of Adobe PPD specifications. If your application software supports version 4.2 PPD files, the DocuPrint PPD files should be used when generating print documents from your application.

If your application does not support version 4.2 of the PPD specification, the Generic PPD file can be used. In the cases where using the LaserWriter PPD file results in PostScript code that contains operations not supported on DocuPrint, use the “NULL” PPD file that is available with some applications.

Implementation limits

Features that are known to be device dependent (see the Adobe PostScript Language Reference Manual, 2nd edition, for a list) may differ from other implementations. These include performance, VM usage, certain kinds of shading and line thickness, some kinds of halftoning, resolution dependencies, and certain implementation limits.

The following table lists the implementation limits that are not defined in the PostScript standard, but are inherently different on PostScript devices.
