ColorSync (ICM in Windows) tells the driver to do the conversion from the
image color space to the printer color space. For this to work, the image
must be tagged with a profile (e.g., Adobe RGB). In Photoshop, you do this
by selecting "Printer Color Management" under "Print Space".

No Color Adjustment tells the driver that the image is already in the
printer's color space. For this to work, you have to convert to the color
space in your image editor. In Photoshop, this can be done automatically as
you print by selecting the appropriate profile under "Print Space". If
you're using some editor that supports profiles, but doesn't have this
feature in its Print dialog box, then you can do an explicit profile
conversion (not assignment) before printing.

The advantage of the former is simplicity, but you can only select the
profile choices built into the driver. The advantage of the latter is that
you can use any profile, and choose the rendering intent.
