Overview

Most software applications do not require you to enter printer commands. See your computer and software documentation to find the method for entering printer commands, if needed.

PCL 5e printer commands tell the printer which tasks to perform or which fonts to use. This appendix provides a quick reference for users who are already familiar with PCL 5e command structure.

The printer has the ability to print vector graphics using the HP-GL/

2graphics language. Printing in the HP-GL/2 language requires that the printer leave PCL 5e language and enter HP-GL/2 mode, which can be done by sending the printer PCL 5e code. Some software applications switch languages through their drivers.

HP’s Printer Job Language (PJL) provides control above PCL 5e and other printer languages. The four major functions provided by PJL are: printer language switching, job separation, printer configuration, and status readback from the printer. PJL commands may be used to change printer default settings.

The table at the end of this appendix contains commonly used PCL 5e commands (page D-6). For a complete listing and explanation of how to use PCL 5e, HP-GL/2, and PJL commands, download the PCL 5e /PJL Technical Reference Documentation Package (page 11).
