Uli, Chris, and Roger,
I was just reading parts of HPs manual for the 9500. The printer can be
set to "device" when in RGB or CMYK mode which is the "dumb and
hopefully repeatable" mode intended for use with application or system
based ICC colormanaged workflows. These settings are available through
the manual options in the Color matching pop up in the print menu, or
so they say. What is not explicitly clear is that these setting as all
available in both the Windows and Mac drivers. Uli, do you see 3 RGB
options, 5 CMYK options, plus halftone and neutral gray options?
According to HP Automatic assumes the file is sRGB. You could try
sending a sRGB file, but then you'd be limited to RGB and could not
make your own profile.

I don't think he's using Adobe applications, but rather mostly Cocoa
applications.
Correct. :-)
Therefore he has to depend on OS-level color management. I think the
ducks are all in a row in his situation except that the driver
settings aren't set the same way as when HP built the CMYK ICC
profile and that's why it prints too dark. Uli needs to find out what
the proper driver settings are FOR THAT PROFILE.
What kind of "driver settings" do you refer to? The PPD specific
settings that the Print panel offers? (These aren't too many, apart
from paper thickness ...)
And even then it's possible he'll need a custom profile. Laser
printers are notoriously inconsistent without external hardware based
calibration at least a couple times per day.
Well, it isn't that bad ;-). If I switch off ColorSync for printing
("Color Conversion: In Printer"), the output has been relatively
consistent, and it comes close to what I see on the screen.
It's just that I still want it to be a bit closer, and want to be able
to use a custom profile (at least in the longer run); therefore, I
want to get the printer to work with ColorSync. (But to stay on topic,
it's probably better to move this discussion to the other thread.)
Bye
Uli
