Hello Mr. Moon. I tried everything but it still did not work. I even re-installed Catalina.. I am a novice with Apple computers even though I have been using Apple products for 15 years. I have a 15 inch MacBook Pro (2019) and it has not been able to print using Wi-Fi. I am not able to add the printer at all in the systems preferences printers & scanners section My previous MacBook Pro (2013) worked with this printer. My Apple iMac 5K works with this printer over Wi-Fi. Everything works with this printer over Wi-Fi except this new MacBook Pro.
My iPad mini and iPad Pro work with this printer. My ASUS Laptop works with this printer. I am able to print and scan with my computers and even my iPhone11Pro Max works with this printer over Wi-Fi. I read the instructions and performed them to the best of my ability. When it would come to the point that I was adding the printer software to the computer I would wait for about two minutes and then Epson would show up but only for the FAX which I don't need and have never had a fax. Whether I was using AirPrint or the IPP protocol it would only show on the AirPrint section. When I would touch the "next" button it would come back with an error.
I love my new MacBook Pro as it is the Core i9 chip with eight cores. It seems faster than my 2013 MacBook Pro. I am happy with the MacBook Pro in every respect so I will live with this small problem.
I thank you very much for your help and wish you good health in your life. Thanks again. Eyes so good (ojossogood)
