"Color/Greyscale" allows me to print half-toned grey scale (i.e. it
shades topological plots from mathematica correctly).

"Black&White" ... "Gives you the same result as the version 5.2
laserwriter driver" (Apple's 6.0.1 teachtext document)

I looked quickly at the postscript output from the "Black&White"
option, and it only uses two grey levels: 0 and 64.


In other words, this is a serious Apple bug.  It is already so common
that I have written a program to filter these stupid "setrgbcolor"'s
out of my postscript file, before printing.
