Trying to resolve a message "encryption credentials have expired". Using MacBook Air OS 13.0.1 and an Epson 7620 printer. Computer won't allow printing, have deleted and reinstalled printer, etc.
Any assistance appreciated!

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!
Perfect solution!!
Thanks
Thanks. I originally went the route of downloading an updated driver from Epson, etc. It worked... for a few days. Now I've followed your advice and I'm printing again. Fingers crossed!
I'm so glad I found this while on hold with Epson. It worked for my WF-4630!
YanAvery, you are a printer deity!
Spent way too long trying to find the certificate to update and your answer was perfect.
May printer drivers never darken your doors!
