HP provides an example program called bmprint.  It uses Starbase framebuffer
driver to dump the screen in PCL format.  The file is contained in directory
"/usr/lib/starbase/formatters/pcl".  There is documentation on it in one of the
Starbase manuals.

I have found this program to be significantly faster than xwd plus it gives
much better grayscaling. This program will only work on HP's, and you can't
dump remote displays.
