This couldn't be the furthest from the truth if you tried. D-76, or any film developer for that matter, will work rather nicely on paper. Yes it will give you a different scale/range (flatter) but you can still get maximum black, and true whites. The dev. time will be different, and I can't remember what dilution I used...either straight or 1:1, but you can do 1 of 2 things...expose for longer, or develop longer. It will take some trials, and paying attention while you do them, to learn the dev. but once you do, you will find it can offer quite a lot.
The fact that the poster above discounted it proves he hasn't used it to print with. I have and even some of the prints I've done with it have ended up in museums like SFMOMA and the Corcoran.
So there
PS: just FYI, PE, I like a lot of your other posts an am not being mean or discounting your experience. But in this field, my experience is more than yours.
