  Alright, well, I couldn't pass this one up.  This, as taken from comp.
lang.postscript, is not correct.  The big problem here is that Macintosh
uses a file from it's system folder called Laser Prep.  This LaserPrep file
contains definitions and routines that are called as the md dictionary
from the EPS code.  If you take a look at the generated EPS from a macintosh,
it WILL start with the traditional %!, but you'll also notice that a few lines
down in the header there's:

%%IncludeProcSet: "(AppleDict md)" 68 0

or the like, and the first non-%% line is:

md begin

therefore, you need to have the md dict defined previously.  The Mac will do this
automatically by sending the LaserPrep file to the printer before it's first
print job, but unless you get the EPS using the CMD-K sequence (I'm assuming
you're using the CMD-F sequence, you didn't say) the LaserPrep file will NOT
be in the generated EPS.  Now, if you ARE using the CMD-K sequemce to get the
EPS saved to disk, I don't know why it wouldn't work on any postscript printer,
but, I tried that once or twice myself, and it didn't work.  I eventually found
a shell script that would prepend the proper version of AppleDict md (in my case,
68, which cooresponds to LaserPrep 5.2 on the Mac) and do one or two other minor
things to the EPS before sending it to the printer via lpr.  

  If this is any help, I'm happy to have helped, if I'm wrong, go ahead and tell
me about it.  I know that my way works, cause I use it all the time, and I'm
99 44/100% sure that what was posted by Susannah Skyer will not work as she
posted it.  Maybe I'm not reading in what was supposed to have been read in
that would make it correct, if so, I appologize.  Enjoy, and any information
can me sent to me at chris@super.org.

                                    Just trying to be helpful--
