PostScript Printer Driver

The Windows NT PostScript driver uses Adobe version 4.2-compatible PostScript printer description (.ppd) files. (Windows NT does not use the .wpd or .mpd files used by Windows 3.1). This driver supports key features, including binary transfer compression from Level II, resolution, and paper source.

The component files of the Windows NT PostScript printer driver are as follows:

• Pscript.dll is the printer graphics driver.
• Pscriptui.dll is the printer interface driver.
• x.ppd is the PostScript printer description (PPD) characterization data file.

Note PPD files are the only printer driver files that are generally binary-compatible across processors and platforms.
