Attached below are the various printer drivers available via LPRng.
These are the keywords used in the 4th field of plotter.data which
basically describes what type of printer it actually is.

The printer types available with LPRng queues set up through plotter.data are:

8830:  Used for Xerox 8830 plotters

bogusqueue:  Used for the bogusqueue only
   This printer type will send email back to the user for any print job
   sent to it stating that the user did not specify a printer to print
   to and does not have a default printer set.

distiller:  Used as a drop spot for the Acrobat distiller
   Jobs sent to this queue need to be postscript files.  They
   get dropped in /appl/distiller_files/IN.  Sometime later, you will
   get a .pdf format file in /appl/distiller_files/OUT.
