Unfortunately no answer yet!
i just got a new 16" Mac Book Pro with Catalina. We have a Xerox 7100 in my Bonjour network which usually works great. We can print without problems on a 15" Mac Book pro from late 2013 (also with Catalina). On the new one though it seems i can not add a correct driver.
For example i can not select paper size A3, which is actually big problem. Any ideas of how to solve that? I could maybe copy the driver from my late 2013 mac book pro, but don't know where to find the driver and if that would even work. Any help appreciated!!
