In 1993 or so I wrote some software to print images from my video frame
grabber to a HP LaserJet printer. I ordered the HP technical manuals for
PCL5; they were free with my LaserJet 4. The manuals weight 7 pounds and are
available for the cost of shipping. If no one wants them they are off to the
recycle bin.
