Surprising, I would have thought, that if you sent it CMYK ps then that
is what it would print.

We have a Xerox colour laser at work, and get excellent colour, sending
CMYK postscript directly to it. Colours are unchanged from what is in
the file, but maybe that is unusual. We did go around and fed files to a
lot of printers before we picked this one, and many others did not fair
so well. Also many printer salesmen are clueless....

Maybe it's worth checking that the PS is not mangled some how between
the file and the printer.
