Overview
Most 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 The table at the end of this section contains commonly used PCL 5e commands. (See “Common
PCL 6 and PCL 5e printer commands” on page 179 .) 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 6 and
PCL 5e PCL 6 and 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 6 and 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.
