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.
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).
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.
