Where I used to work, our Xerox 9700 only printed 120 ppm when doing
computer program listings in a constant width font.  When printing
troff documents or graphics, its speed fell below 100 ppm, and was as
slow as 60 ppm.  PostScript isn't the only thing that runs slower when
it's working hard.

When will the Professional Graphics Set be available commercially?
