We have a few color postscript printers around here.  The site
spooler (not a symbolics) will take color postscript using the
same protocol used for black and white.  (LPD I think.)  I
would like to generate some color stuff from our symbolics.
How do I do this:

1) make a namespace object that indicates color, (if so, how?)
2) manually open a special hardcopy stream that knows
   that color is in play, (if so how?)
3) something that I haven't thought of, (if so, what?)
4) you have a hack that does what I want, or
4) not possible with the symbolics-delivered software, and
   you don't have a home-brewed solution.

I value possibilities in the order they appear in the list.
Any help would be most appreciated.
