HP-UX 11i v3 International Printing Features

PJL

Printer Job Language (PJL) was developed by HP for providing job-level control that cannot be

accomplished with PCL, PostScript, or other printer languages. To provide this control, PJL functions

“above” the level of PCL and other printer languages, providing four major functions:

• Printer language switching between jobs

• Job separation

• Printer configuration

• Status read-back from the printer to the host computer

Other printer manufacturers might use their own job-control language similar to PJL for these job-level

functions.

PostScript

PostScript is a stack-based page description language created by Adobe Systems. It comprises a

group of ASCII text commands and codes that describe graphic elements and indicate where they are

to appear in the printed page. A PostScript printer contains a PostScript interpreter that interprets the

PostScript commands and executes them. There are three levels of PostScript – level 1, 2, and 3.

PostScript level 1 is now obsolete and current PostScript printers support either level 2 or level 3.
