Hello:

Can anyone tell me what exactly is the difference between hpgl2 and hpgl?

I believe that hpgl2 simply has an expanded command set. What are these?

Thanks,
Tom

There are many extra commands and extensions to commands. A few I can
think of off the top of my head:
Default 0,0 is in the corner instead of the center
extra rotations (180 and 270)
BP (Begin Plot)
QL (Quality Level)
PC (Pen Color)
PW (Pen Width)
PP (Pixel Placement)
LA (Line Attributes)
many others I can't think of right now. The above were the biggest effect
on what I wrote for. Many of the enhancements were to support raster-mode
(laser/inkjet) enhancements that the old vector pen plotters couldn't do.
