Depends on where you are in the chain. In my case, the OS has already ripped
the page into RGB pixels and I know (at least I think I do) the source
profile. Thus, armed with a CMYK profile I was hoping to convert the page
data directly from source RGB to printer CMYK.
Thanks,

No OS print driver prints in more than three colors. If you have a
CMYK printer profile it must have been built with a Postscript RIP or
an image export module from Photoshop. These are the only ways to
send data to the printer in more than three channels.
