This error occurs when the Printer's web certificate has expired.


For me, to resolve this problem, I had to go to the printer's web interface, typically using https://<your_printer_name>.local/ and from there, you go to the following menu option:


Network Security Settings -> SSL/TLS -> Certificate.


From there, you choose the "Update" button form the "Self-signed Certificate" section.


This will have you go through the generation of a new self-signed certificate for your printer's web GUI which is also what Apple uses as it goes over HTTPS when communicating with your printer. I left the "10 year" suggested value for the "Certificate Validity (year)" field, this way I don't run into this problem for quite a long time.


Following that certificate update, I removed and re-added the printer from the Apple settings, didn't need to go through any of the Epson utilities.


I hope this helps!

I tried all the "advice" from several web sites and NONE worked! Spent several frustrating hours to no avail ...


Saw the timystic and mmitchel posts ... Deleted the existing Epson drivers. Went to the Epson website and downloaded the installation program, launched it, installed the software and made sure the Wireless SSID I wanted was set up on the printer .... BAM! Everything now works!

Thank you YanAvery, this is actually the correct solution. If you go to your printer's webpage (Open the print queue > Click the Gear and select Show Printer Web Page...). If Safari is your default web browser, it will say This Connection is Not Private with an option to view the certificate. Mine expired on 12/29/2022. Following these direction updated the certificate. It now expires 1/8/2033 and I can print. This is the solution to fix it correctly while maintaining security.
