This is a filter for pbmraw streams which can be used with, for example,
ghostscript + CUPS/foomatic, allowing one to make use of these printers
under non-Microsoft operating systems.  Their print quality is excellent
for the price ($99 or less), but they're utterly dumb devices which
require the driver to do all of the work.
