Maybe this is the case with some bad or misconfigured Windows drivers, but
at least every properly configured Mac OS color printer driver will take
CMYK input and create appropriate results.  And it will do so on all
PostScript printers, which at least includes the HP Color Laserjets.  Of
course, what Windows does if you use a GDI printer or printer driver may be
something completely useless.....
