When I grew up as a teenager in the 1930's, my father exposed his
photographic prints in the sunlight in the window. I don't think he used a
fixer and simply washed them, but I am not sure on that. The prints were
brown and of good quality. It seems to have been a common process at the
time.
I am trying to find the name of the process.
On the internet, I came across the names of "gum bichromate"and "salt
paper", but I think these were much earlier processes. "Cyanotype", I think,
makes blue prints.
Any help?

It is called "Printing out paper". Usually used for client proofs
since they didn't last unless fixed. There may still be some of this
paper produced by the specialty makers.
