xpr for HP-LaserJet?

[Robert Elliott Smith]

Hello,
 I am currently running Ultrix through X-windows on a Vaxstation 2000.
I also have an HP-LaserJet hooked up to the system.  I have lpr working
correctly with the HP (if any one wants details, I'll gladly fill them
in).  What I would like to know now is if there is a version of xpr that
works with the HP.  The man entry informs me that xpr converts a file that
contains a x-window image (dumped by xwd) to a format that the DEC LN03
printer understands.  Is there a version that can do the same thing with
the HP-LaserJet?  Is it PD?  The version on my system was written by
Michael R. Gretzinger at MIT project Athena.  Any correspondence that may
help is appreciated.

                                               Thanks, Rob Smith.
