Changing the Graphics Language
Your software application communicates with the
printer by a graphics language. The printer's default
language setting, called Automatic, it works for most
software applications. In Automatic mode, the printer
determines which type of file it is receiving i.e.
PostScript or HP-GL/2, and prints it. Unless you are
troubleshooting any of the problems listed under
Comments in the table below, you should not need to
change this default.
