Exactly, Graeme.
The route that Apple has chosen moving forward is that color management
is always enabled during print -- with one exception (see below). The
application can tell the OS that it is handling color management; the OS
then effectively sends the resulting image data (appropriately tagged)
to the printer driver, without further modification. Otherwise, the OS
assumes the application isn't going to take care of output color space
conversion, in which case the OS will do it automatically.
Exception: There *is* an Apple-specific way to tell the OS that you want
no color management (e.g., for doing things like printing profile
targets). However, it is intentionally not publicly documented, and you
would have to ask Apple directly for the specifics. I do not know the
details myself.

The correct, robust method is to tag the image with a flag
that says "Image is in output device space, do not color manage",
but unless someone like the ICC comes up with a standard that
uses the ICC format for such a thing (a meta profile), it is
still going to be printing system or operating system
and print file format dependent.
