Why is printing with No Color Management not supported in CC? If you choose the Document profile and Printer profile to be the same you get a warning that "It appears that you are attempting to print without color management. Please use the Adobe Color Printer Utility.." Whenever the source and destination profiles are the same, a CMM will do a "null transform'', in other words it will do nothing and leave the image data unchanged, so we create a condition of printing with No Color Management. We can use this to print a test target, for example.

Does Photoshop not like this because it hands off the image to the printer driver, and Photoshop can't guarantee that pixel values will be untouched and not color managed by the (often free) printer driver?? The user will not get what they expected and blame Adobe, while it was really the fault of the printer driver?

That hasn't been supported for a while - because the OS vendors don't want it supported and made a lot of changes that make it more difficult (a moving target) to get non color managed prints.

No, the current printing code on Mac and Windows usually won't do a null transform when printing - that is part of the problem.  This has more to do with the OS than the drivers.

I haven't tried to do this for a while but  the "Adobe Color Printer Utility" used to be able to print with "No Color Management".

Yes, we wrote the utility specifically for non-color managed printing, following specific requests from both OS vendors to make it work (which is @#%$@#%@# different from the normal print code).
