I'll toss in two cents here. I did a bunch of experiments last night,
and while I never was able to be absolutely certain that my experiments
properly controlled all variables, I got a very strong impression that
changing the default colorsync profile for my printer did affect the
printed output, even when I chose "no color adjustment" in the printer
driver.
Here is what I did:
I opened an image in photoshop, and specified in photoshop my custom
printer profile. I set the printer driver to "No Color Adjustment".
Looking at the summary page available in the printer driver, it stated
that I was using the EPSON RGB Standard profile. (Even though I "had
colorsync turned off"). I then printed the image and it looked
"right". Then, I went into the colorsync utility and changed the
default profile for the printer to another profile, and went to print
again. In the summary page, this other profile was specified where
Epson Standard had been previously been specified. I printed this
image. The two prints were different.
Therefore, it does seem to me that there is no way to really turn off
colorsync in the printer driver. Further, it means that when I printed
out the target which was used to create my custom profile, I was
actually using this epson standard profile when I thought I was using
no profile at all. This means that my profile will only work when I
apply it first, and then apply the epson standard profile. The only
way I know how to do this is by printing with photoshop. I will not be
able to use this profile with other applications.
This really does not need to be this hard....
Not angry, just frustrated. I'd really rather be making prints than
figuring out how to make prints.

Setting the clearly angry tone of this thread aside:
Sounds like you are confused as to how to apply printer profiles in
PS. I don't recall at what version the printer profiles started
working right (it was long ago) but as of v.7 "convert to profile"
works fine for printing under both 9 and X.
Printing with "no color adjustment" in the printer driver after
converting in PS to an appropriate printer profile is definitely the
best (most control, most consistent) way to print RGB files (without a
RIP) in my experience. It works in PS 7 with both printer-supplied
drivers and also PostScript drivers, even of the generic kind (for
PostScript capable printers).
If you detail your step by step procedure, I am sure someone on this
list can tell you what you are doing wrong.
There is always room for improvement, but to say or imply that
printing is currently broken in PS on the Mac is entirely inaccurate.
If you are having problems, and it sounds like you are, please try to
not give in to your frustration and instead systematically try to find
a solution. We can all learn from your experience, whereas venting
your frustrations helps only yourself.

photoshop
puts into the printing system is tagged with the Generic RGB
Profile,
regardless of the actual profile. Think about it for a moment and
you
will realize that the ONLY way photoshop is going to be able to
correctly print an image that isn't already using the Generic RGB
Profile is to have photoshop convert to the output space and hope
that
the printer registers "Generic RGB Profile" as the printer profile
when
you select "no color adjustment". This certainly explains why my
"Same as source" printouts never looked right. An Adobe RGB file
printed with "Same as source" will have Adobe RGB data that the
print
system will interpret as Generic RGB. (I'd really like to see if
Photoshop CS behaves differently.)
