Digital BW, The Print

In 10.5 Apple has pulled back support for "No CM" so your best bet for
profiling targets is to use Printer Manages color and then make sure
the print driver is set to CM off. When set to Printer manages color,
PS just passes along embedded profile and rendering intent info. PS
does no conversion on its own, it just makes profile and rendering
intent info available to the print driver. Whether the driver receives
that info correctly and/or knows what to do with it depends on the
particular print driver. But for most current drivers Printer Manages
color should provide identical results as No CM; with the appropriate
driver settings.
