Operating System: macOS 12.0 Monterey
Everything set up, Mac can see the printer but cannot connect to print, get "printer not responding message". Have another old Mac and have same problem wit this one too.
Downloaded all drivers, firmware, updates etc. Also run connectivity test from printer and all looks fine. I am now sat with Mac and printer right next to the wifi router and still not working...guess the printer has a problem...?? Help 🙂
