All Open photos get printed, and I only wanted one printed.

Chatting with a user in a PSE elements page on Facebook:  All the photos in the photobin were getting printed, when they only wanted one to print. They are on a mac using pse 2021, I use pse 2022. 

I has a simliar issue a while ago, I fixed it for me by updating my printer driver- which I hadn't done in over a year anyway.

I stumbled across an idea this morning, and it solved the users problem.   Does this work for others?
