Thanks Roy for your reply! So what I am getting from your message, if I understand it correctly, is that it is fine to print the step wedge from photoshop with ABW mode and "printer manages colors". This will give me a wedge that I can measure where no monkeying has happened from the computer side and the printer has done its own stuff. Now, once I have an ICC profile, if I wanted to apply it, there is a simple way to do that through QTR for mac, but not windows. Correct?

I was not thinking of printing through QTR, my idea was instead to follow the flow from http://www.northlight-images.co.uk/print-setup-for-a-new-fine-art-paper/ described under "using a linearising profile". The idea, as described there, is to "take the monochrome (greyscale – profile Grey gamma 2.2) print-ready image, assign the QTR profile and then convert back to greyscale for printing" where printing here is taken to mean using photoshop with ABW mode. The idea, as far as I understand it, is to essentially rescale the image to offset the nonlinearity and then print with ABW like normal. Does this make sense to you?
