Reconfiguring Your Printer
Changing the Graphics Language

Graphics Language and Networks
For system administrators
If you are using the printer with a network spooler, consider having your system
administrator modify the spooler to insert automatically the PJL language-
switching commands at the beginning and end of each file. This allows the printer
to switch automatically into the correct graphics language for your current print and
returns the printer to the front-panel graphics language setting for subsequent prints.
For information on ordering PJL reference information, see page 13-18, Ordering
Accessories.
The HP PostScript printer driver for Windows provided with your printer, adds the
PJL language-switching commands to your output file, allowing the printer to
switch graphics languages automatically.
NOTE:When using a Macintosh you should select the Automatic or Postscript
setting, otherwise you will not be able to connect to the printer.
