I had to happen! The only person who uses printer to any significant degree in the office is unable to print properly from Linux !!!
Same setup, same drivers, printer on same machine works perfectly from every other Linux/Windows machine
Unfortunately it works properly from that very machine when booted in Windows and still more unfortunate the trouble started when the machine was upgraded to RH 7.3 from RH 7.2
Redoing a complete forced upgrade did not work either – will have to try a reinstall
No point for guessing whose machine this is 😉
