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 deleted the printer, reinstalled it ... deleted all the printers and reset the printer system settings, restarted the computer, etc. First five times times it did not help. Did it again ... and 6th time was the charm.


So I have absolutely no idea what the actual solution was, but I'm working again.

Go to timystic's advice above: "I ended up deleting all the drivers, switching the printer and laptop off for 15 minutes and then installing a driver from Epson directly (you have to make sure that it's set to 13.x which it does not autodetect). Using Epson to install the printer instead of the Apple System interface."


That is what worked for my on two Macs using 13.1.
