HP 4100N, 4100TN manual Printer commands

D 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 5e	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.
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 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.
PJL	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.
Note	The table at the end of this appendix contains commonly used PCL 5e
	commands (see “Common PCL 5e printer commands” on page 239).
	For a complete listing and explanation of how to use PCL 5e,
	HP-GL/2, and PJL commands, see the HP PCL/PJL Reference Set,
	available on CD (HP part number 5961-0975).
