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 (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 CD (page 7).
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.
Note
Unless PCL 5e backward compatibility is required, HP 
recommends that PCL 6 printer drivers be used to take full 
advantage of all printer features. The PCL 5e printer driver in this 
printer is not backward compatible with older printers that use PCL 
5e printer drivers.
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.
