Printer Commands

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	PCL 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 command structure.
	•	The PCL 5e printer commands are backward-compatible with
	•	previous versions of PCL.
		The PCL 6 printer commands take full advantage of the printer’s
		features.
HP-GL/2	The printer has the ability to print vector graphics using the
	HP-GL/2 graphics language. Printing in the HP-GL/2 language
	requires that the printer leave PCL language and enter HP-GL/2
	mode, which can be done by sending the printer PCL code. Some
	software applications switch languages through their drivers.
PJL	HP’s Printer Job Language (PJL) provides control above PCL 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
Note
	PCL 5e commands (page D-5). For a complete listing and
	explanation of how to use PCL, HP-GL/2, and PJL commands, order

the PCL 5/PJL Technical Reference Documentation Package (page 8).
