If you are getting better than 72dpi output, then that's as good as it
gets.  I am somewhat surprised at how poor the postscript greys look
at 300dpi.  Somewhere I read that there were only 20 distinct shades
of grey available.  I don't understand why there aren't 17 or 65 or
some number like 2^n + 1.

I have tried printing mathematica plots a NeXT laser printer at 400
dpi and the result looked about twice as good.  I don't know if it
generates grey scales differently, but it sure does a better job.
