Hi Graeme.
I would like to use this opportunity to ask the group to clarify one thing
for me, if possible.
This is what the Photoshop Help file for Photoshop CS (v.8) has to say about
the "Printer Color Management" option in the Color Management portion of the
"Print with Preview" dialog box (I apologize for the longish quote):
*****
"5. Set the color management options and click the Print button.
Select Show More Options. Choose Color Management from the menu in the More
Options area. Select Document for the Source Space. If you want Photoshop to
handle color management during printing, choose your printer's profile from
the Profile menu in the Print Space area. If you prefer to let your
printer's driver handle the color management, then choose Printer Color
Management from the Profile menu. Click the Print button. The Print dialog
box closes, and a second Print dialog box opens.
Color management is essential for producing consistent color when printing.
Whether you let Photoshop or your printer driver control color management,
you'll get the best results using a custom profile for your printer and the
specific type of paper you're printing on.
6. Specify the printer settings.
In the second Print dialog box, choose your printing options. On Windows,
click the Properties button, then the Advanced button, to access the printer
driver options. On Mac OS, use the pop-up menu to access the printer driver
options. If you chose Printer Color Management in the previous step, specify
the color management settings. If you're letting Photoshop control the color
management, then make sure any color management options are turned off.
Do not apply color management twice to your image. Unpredictable print color
will result if color management is done with both Photoshop and the printer
driver simultaneously.
7. Print the image.
Once all the settings have been made in the printer options dialog box,
click the Print button."

As you can see, there is no mention of exactly which "color management
settings" could or should be activated in the second Print dialog box.
Taking as an example what happens with the printer driver for my Epson 2200,
I do not see any place in that dialog box to select any of the "color
management settings" that are hinted at in the Help file.
It seems to me that this "Printer Color Management" option offers no true
color management choices, but just a way to use the driver the same way one
would do without having access to the Print With Preview dialog box in
Photoshop.
I find it confusing that this is being referred to as "Printer Color
Management" in the application, whereas it appears to me that it has little
to do with "color management" in its common meaning (i.e., the choice of two
specific profiles -- source and destination -- plus rendering intent and,
possibly, BPC).
I would like to hear from others what is their own understanding of the
"Printer Color Management" function.
Thank you.
