Ok, it's getting pretty late in the day, so I had better ask my 
bone-head question of the day if I'm going to get it done.

Is HPGL at all like PCL?  I'm not very familiar with printer languages 
other than Postscript. The reason I ask is that the Epilog laser cutter 
to which I will soon have access is rumored to run on slightly tweaked 
PCL5.  Epilog does not publish specs, but some work has already been 
done to reverse engineer the protocol, and from what I gather it is 
mostly PCL5.
