You're going to want to use GhostScript for your PostScript
interpreter. It already does a good job of interpreting PostScript,
so you don't have to write one from the ground up. Then all you

the basic set of functions to instead output the vectors that should
be plotted to a file or stdout.
From there your PC can just chew through the list of vectors and
tell the RCX what to do.
This is essentially the method I used to turn my HPGL plotter into
a PostScript plotter.

I was searching for information on a Postscript->HPGL/PCL converter myself since that is basically what (...) (25 years ago, 24-Jun-00, to lugnet.robotics)
