D Printer commands
Most software programs do not require you to enter printer commands. See your computer and
software documentation to find the method for entering printer commands, if needed.
Note See “Common PCL 5e printer commands” on page 172 for a list of commonly used PCL 5e
commands. 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-ROM
(HP part number 5961-0975).
PCL 5e PCL 5e printer commands tell the printer which tasks to perform or which fonts
to use. This section 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 programs 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 can be used to change printer default settings.
