HP Support pages at the front of this user
guide.)
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.
