In which case this is an RGB printer based on its marking engine and

Yes. So what? It's an RGB printer. What possible reason could there
be to treat it as something else?
And even with the CcMmYK printers that insist on being driven as
RGB devices, I would strenuously disagree >that they're more
trouble than they're worth
An application that has a CMYK imaging model (which again means it
is able to use the PostScript printing pipeline and bypass the OS
pipeline), and that has a CMYK object to print through the OS
pipeline, must convert that object to RGB, whether that conversion
is color managed or not color managed.
Yes, so what? As long as the thing produces the expected response to
stimuli, I really don't care if it uses CMYK, RGB, YCC, LAB or
hundreds of little gnomes.
If you look back on the List over the past three years at the welter
of questions clustering around this, and around the implementations
in drivers and applications that try to handle it, and we still
disagree that this is a limitation for desktop publishing, then
let's agree to disagree -:).
Desktop publishing? Haven't heard that one for a while. If you mean
that it'ssomewhat inconvenient to use a device that insists on being
treated as RGB to proof CMYK, then yes, it's a small inconvenience,
but one with which I can easily live. The Epson 1270 "proofs" that I
supplied for visual guidance with Real World Photoshop 6 turned out
to match the press sheet a great deal more closely than the printer's
in-house Matchprints (which they admittedly confessed were not a good
predictor for direct-to-plate printing). The people I see having
trouble with these devices are the ones who insist on trying to drive
them through a RIP, occasionally for good reason, but mostly for bad
ones.
Me, I'm very happy having a $400 printer that comes pretty close to
an Iris (only much more reliable), and produces very predictable
output day after day.
