Digital BW, The Print

I was printing out a stepwedge tonight and it suddenly hit me that I don't know what 
difference there'd be between printing the untagged file with No Color Management and 
printing it with Let Printer Determine Colors.  Does it make any difference which way you 
print the test file if you're using the ABW function of the Epson driver?  Seems to me it 
shouldn't.

I'm not sure what you're doing here in "printing a test file."  If 
the step wedge is going to be used to produce a QTR ICC profile, you 
should use "let printer determine colors" ("no color management" in 
CS2) because you don't want PS to change the numbers sent to the 
printer.  If you are already using a QTR ICC printer profile, you 
should use "Let Photoshop Determine Colors," and you should select 
as  the printer space the ICC profile you created.  The fact that the 
file is untagged is not relevant because PS is going to assign the 
default working space for screen display and modify the numbers sent 
to the printer (to match the screen) if PS is managing color.

As an aside, if the printer space is the same as the default working 
space (or the document profile), then it doesn't matter which setting 
you select.
