Untagged RGB is tagged with Generic RGB. Untagged CMYK is left
untagged CMYK. (So you could print a CMYK target to a PostScript
printer from Mail.app, and reliably get an unmodified target from
which to build a profile. Not so for an RGB target.)
It would be interesting to know if this behavior changes for a
printer that, unlike the CLJ 5500, defaults to an RGB color space.
The reasoning could be: tag untagged images with a color space other
than the printer's default color space (because they have to be
converted), but leave alone untagged images in the printer's default
color space (because they can be sent to the printer as is).
That's not how the diagrams I've seen of how the printing system makes
its assumptions.
But maybe the diagrams are wrong? ;-) I know it's not probable, but I
would give a PPD with RGB as the default color space a try, just to be
sure ...
