Encryption credentials have expired All my printing jobs sent wirelessly to my Epson WF-7611 printer won't print. I got the message "Encryption credentials have expired". I tried most of the methods suggested by the community but with no success. By the way, all 3 MacBook users in my family received the same message.

Printer Encryption Credentials Have Expired on Mac Hello guys One of my clients had me visit for a few Mac related reasons and the last thing on the list was the printer encryption expiring. Their Mac is a 2017 MacBook Pro Touch Bar. It was easy to create a self signed certificate in the Epson web interface but it hasn't solved anything. The printer was working fine a week or so before this week and no updates to the system had been applied. The printer firmware is up to date. It was running Monterey when the issue first reared its head and there is no difference now ive updated it to running Ventura. Next part of the puzzle is that my 2018 MBP also running Ventura also could not print when I tested and had the same issue. The printer is Bonjour not AirPrint so the choosing a different protocol solution is not possible. I tried using LPD and first with the generic driver, which printed gobbeldy gook and then with a Gutenprint driver and it just churned out reams of blank paper. Ive read here and also heard on the grapevine that this is actually an issue with the Mac security systems. Here's hoping someone could offer some light on this Thanks very much Lee

Maybe you need to setup it from a scratch. Here's a default guide:

Add a printer to your printer list so you can use it on Mac – Apple Support (UK)

Also, you can find and use a WPS buttons both on printer and router sides to quickly setup them without network credentials and then proceed with the setup.

And here's another:
