There you go Doug; a lot of useful info ignored. This push back reminds me of a good movie quote:

"What is your major malfunction, numbnuts? Didn't Mommy and Daddy show you enough attention when you were a child?"
-Gunnery Sergeant Hartman, Full Metal Jacket (1987)

Since the OP has gotten an answer to his question and all is well with him, maybe he'll lock the thread and save us all a lot of time....  ;)

That didn't answer my question, Doug. I asked if you or anyone reading here has come across a big box store printer where they required the final image to be printed be tagged with the appropriate profile? And was told why it needed to be tagged whether for the photo lab tech's use and or printer driver conversion.
It's entire possible some ill informed person at such as store would require converted, tagged image files. So the question is along the lines of "Are there fools at stores with incorrect knowledge?" It makes no sense. The RGB values in the file are what gets printed. No conversion using the profile is done. The Profile is ignored.

No point mentioning Photoshop since I haven't seen any big box store printer have Photoshop on their system.
Of course not. Read what I wrote. Photoshop provides a way to soft proof a converted image, tagged or untagged, in printer space. It's not used by the printer.

I'm wondering if there's been an advancement in newer big box store printers where they are clearly able to implement some color managed workflow.

Sure, some do internally. The half million dollar ginormous printer Mark mentioned earlier has specs that say they take images in either sRGB or Adobe RGB. Implicit is that they do some color management since there's a pretty big difference between the two. No idea if they have a wider gamut "native" space option. Have to go to the operating manual to find out.

Exactly and the bottom line! The profile only provides a scale of the existing numbers for a preview or another conversion which isn't necessary as the image IS in an output color space (CMS 101).

Maybe we can start a 'go fund me', fund, get an address and send someone this book:

Wow - I never knew there was such a book. I clicked the link and got the description alright, along with a notice saying "This item does not ship to Toronto Canada". I guess they know there are no Dummies in Toronto when it comes to colour management - or to the contrary, the situation is so hopeless there's no point even trying :-)

Indeed, no reason for such a book there. In the US, in the really big states, a must!  8)
