Brief summary: The issue is that with OS X, CS4 is using the newer
Leopard print APIs (the only print APIs supported under Cocoa), whereas
CS3 was using the older print APIs (will not be supported by the OS
going forward). The consequence of using the newer print APIs is that
the printer drivers must also be compliant with the new print APIs;
being compliant with the old print APIs is no longer sufficient.
Moving forward, OS X is taking steps to prevent accidental printing
without color management. This makes it unlikely that you can use the
standard OS X apps like Preview to print profile targets reliably.
Tagging it with Generic RGB will work today, but not tomorrow when Snow
Leopard launches (and switches to a default profile of sRGB, not Generic
RGB). And tagging the target with sRGB tomorrow may not work for the
future (should future versions of OS X switch to another default profile).
BTW, you should avoid printing profile targets from LR. LR does not
provide an option to disable color management, which is what you want
for printing the targets. (Yes, this is by design.) Yes, there are
workarounds, but they will only work in some cases, but not others. Save
LR for printing images -- with color management, of course -- once you
have your (custom) profile ready.

Hi all
first post.
There appears to be some issues with Photoshop CS4 and certain printer
drivers causing issues.

Its not clear if it is a printer driver issue but thinks work in CS3
but not CS4.
If you print to the target from within the profiling software (eg i1
Match) you should get it un-colour managed?

Unfortunately, it would seem that only two applications, namely
Photoshop and Lightroom, have perfectly working RGB print paths at
this time (a few monts ago). This is what I was told, at an ICC
meeting.

Hi folks
Please pardon my query if the answer is already contained in the
archive but
I have not been able to find it so far. My main question is how do
I go
about handling a print profile test image so that no modification is
made to
the colour space in the process.
