Appendix D Printer Commands 481
Overview
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.
