HP Laserjet Printer Description Files
HP LaserJet printer description files do more than describe the printer or its functions. These files act as a translator between the software and printer to command, or invoke, specific features of the printer.
-
PPD File Extension
-
Translated as postscript printer description (PPD), the PPD file extension acts as a set of instructions which turn on specific features of the print job. These files also act as device drivers for all postscript printers and provide a uniform interface between software programs and the printer itself.
File Commands
-
Because the printer description file translates the codes of a specific software-created document, the printer doesn't need to learn the different codes of the software, this file does the translating.
-
Printer Instructions
-
The HP LaserJet printer description files also provide important instructions to the printer for printing a document. The features of a printer are included in this file, which allows the computer to use the printer efficiently.
Paper Size
-
The HP LaserJet printer description files also includes the allowable paper sizes available to the printer, printer memory configuration and the font set available for use on the printer.
