What I am about to say is based on one attempt to make an Imagen printer work,
and I would appreciate being corrected if somebody has better knowlege of what
is going on...

Before I knew about macps and was hacking the prolog files on my own, I tried
to help somebody here in Maryland (Hi, Chris!) make Mac stuff print on his
Imagen.  I sent him several copies of my hacked-up 5.2 and 6.0 files,
and then told him about macps.  He just could not seem to make it work.

Sometime later I learned from a net posting that the Imagen postscript
emulator is not an official licensed Adobe intepreter but one of the
re-engineered ones that people are now calling "clones".

Rather than do a full Postscript emulation, it seems that Imagen instead
rewrote the Macintosh prolog to use their primitive set, and a Macintosh
compatable prolog is installed on every Imagen Postscript printer!  You
just have to know how to call it...

The bad news is that they did this for 5.2 printing, and this is not 
compatable with 6.0 Macintosh command-f files.

As far as I know there is no reason to use Macintosh 6.0 printing unless
you have a color printer.

I do not know if an Imagen-compatable 6.0 prolog has been written, or if
it is available anywhere on the net.
