Bixolon printer no longer printing in Firefox after update

After the latest Firefox update my Bixolon printer no longer prints receipts out of our Lightspeed POS system. It will print receipts if I am using Chrome or MS Edge so it is a Firefox problem. I tried the about:config, print_printer delete and still have the problem. If I go into Control Panel and do a test print it prints fine. '''This is a Firefox problem and I need a fix that works!'''
