This is a situation where attempts to improve the workflow for
ColorSync color management on the Mac have caused widespread color
management problems with Adobe applications and other color managed
applications, with many printer drivers. The grayscale issue is just
one aspect of it. It also shows its head when you attempt to choose a
custom profile with a range of printer drivers from Photoshop CS4,
Lightroom2, or other apps. An unrequested conversion is triggered by
OS 10.5, that trashes your color. Everybody blames someone else; but
the irony is that earlier combinations worked, and now they don't. We
can't get every printer company to rewrite every driver, so claiming
that the drivers should be updated to "fix" it is not practical. On
the other hand, Adobe claims they have done what Apple told them to do
to update their apps. But the result is that printing to some printer
drivers from CS4 requires converting the image to the output profile
in Photoshop, then assigning GenericRGB (in the case of RGB images,
that is), so that the problem conversion is null. Thats a lot to ask
of users, and is not even possible from other apps, only from full
Photoshop.
