Hi David,

I have it on relatively good authority (the RSI Support Tech who handled
my query some months back), that the PS device driver simply does not do
24-bit color except for bitmaps.  She confirmed this with the development

I don't believe that the PS interpreter in color printers has any problem
converting between RGB and CMYK.  It already does that for 8-bit color,
which is the same fundamental problem.

The problem is in the IDL device driver, not in the printer.

Regards, Ken
