Good morning to the OP.
I don’t want to beat a dead horse here, but let me reinforce something that has been said a couple of times in this thread. When you ask for a “print preview” in the driver settings, and it comes up on the screen, IT ISN’T COLOR MANAGED and will look terrible 99.9% of the time. The purpose of this preview is merely to confirm how the image is laid out on the paper. That’s it. Nothing else. The appearance (color etc.) of this print preview HAS NO IMPACT WHATSOEVER on the the original image, or the soft proof version that you’ve tweaked to look “appropriate” for that image on your selected printer and paper (via proper ICC profile applied). And has no impact on what data is sent to the printer.
Ergo, turning off the print preview selection as a way to try to change what is going on with your work flow, is totally a fool’s errand. Don’t waste or invest any of your time chasing that wild goose. Your problem is somewhere else.
Also, though I much prefer Lightroom’s soft proofing and printing to Photoshop’s, if you follow Andrew Rodney’s instructions on proper work flow, procedures, understanding of the process... the same image, printed through Photoshop OR Lightroom, should look identical assuming the same printer / paper.
Good luck as you work through this today.
