When the color engine is disabled, Image print is still dependent the media
profile for a default color transformation. If you disable RGB or CMYK
inputs the media profile must match the kind of target you are printing.You
can't profile CMYK with the tabs set to none if there is an rgb media
profile selected.(I haven't check OSX version, but its probably the same)
The preview and print will be trashed. If you disable only one input profile
who knows what combinations will do.
Also, setting inputs to none also effect other things on Epson's besides
what I have listed. I don't have any Epson's so I don't have the details but
there are a few.

This makes the assumption that the apps are doing it correctly and
Imageprint is not. The reason I say that is because Imageprint never uses a
perceptual table from any ICC profile. It gets data from relative
colorimetric and rebuilds the perceptual table because the guys at Colorbyte
believe that the perceptual table are flawed in all profiles. Well if this
is true than Photoshop set to perceptual will have a wrong preview. I get
matches from my screen to Photoshop & prints -- but I'm mostly PC. Even
though I have 5 Macs.
Colorbytes opinion about perceptual tables is interesting. Ask Robin Meyers,
GIll Grame, Bruce Lindbloom what they think of the current colorsync system?
These guys have to try to build products with the environment.
I've debated a few Abobe engineers about Photoshop and the CPSI engine and
when I trap them proving their bugs and the flaws, the get all pissed off
and say you can buy another product. Same goes for Pantone,
Scanvec-Amiable.
I'm hate buying products that don't function reasonably close to what they
calm. Any product directors who are lurking want a debate - step forward. I
give you dozens of major bugs/flaws that probably can't be solved and render
your product nearly useless in the real world.

Don't you trust your workflow from scanner/digital camera to printer without
looking? I have lots of customers who deal with 1000's of images a day -
they don't have time to look. Howtek seems to like Imageprints Tools because
they have been buying Trident software for years from Colorbyte -- Same
tools in IP. Fuji seems to be ok with it.
The only reason I went so hard on you Andrew is because the are a lot of
newbies that read articles/books that guys like you publish and take your
word for Gospel. A lot of statements you guys make are not completely
correct and cause problems depending on a lot of different things. If Sean
fitzgerald happened to be in a CMYK workflow for printing, he would be
screwed with your instructions. They he would call his dealer possibly me,
Colorbyte and waste everyone's time. As a dealer I get this all the time.
Half the articles I read have major errors in them and yet they get quoted
time and time again by everyone who thinks there an expert.
This color stuff is complex there are no general answers. It's hard enough
to figure out what's correct, wrong statements from apparent experts makes
it even more difficult to find the truth especially for the average enduser.
