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!
I just had the same problem, and went through all of the options on that link.
I can't see how to change 'Secure AirPrint' to "AirPrint' and updating a certificate is not solving the problem. I'm on a different Epson (WF-3620) but same issue.
This approach worked! Very grateful to you!
Boy, it's been a month of headaches from the upgrade to Ventura. First, Calendar dropped my Microsoft Exchange calendar link after the first upgrade, then this printer issue after upgrade to 13.1. I think I'm recovered now; but will never recover the lost productivity this caused.
I have tried everything that Apple suggested and still can't get my Epson WF 4630 to print. I upgraded to iOS 13.1, turned off router, deleted printer, reinstalled it (it was already set at Airprint) and still...nothing. I'm at my wits end. Please help!
When I went to the Epson driver link, the instructions they gave didn't match what is on my MacBook Pro laptop. I can't find the "Library" to select "Printers". There doesn't seem to be any such thing. I just don't know what to do. Is there someone I can call and talk to a live person?
I did everything timystic suggested and it's still not working. I must be doing something wrong but I can't figure out what. This is ridiculous. Shouldn't Apple fix this problem since so many of us have it?
Check my prior post on how to resolve this in your Epson printer configuration. I had the same issue, and re-installing Epson's own drivers didn't resolve this for me neither. But if you follow my instructions, it should work, at least it did for me, and apparently for couple of other folks too. Good luck!
Thanks YanAvery - simple and clear instructions to follow. However, how long would you expect the process to take. I've copied a snippet from the browser window. It just seems to stay like that and does not refresh / update with any result to say the cert is generated. If I close the window and try the rest of the steps the issue is still there. Any ideas? Thanks.
and I notice when I look at the existing Cert via Network Security Settings > SSL/TLS > Certificate, then Self-signed Certificate and click the "Confirm" button, I see:
Validity
Not Before: Feb 9 02:16:57 2023 GMT
Not After : Feb 6 02:16:57 2033 GMT
So it seems like it is valid? But I still have the encryption credentials expired error printing from any app on my MacBook Air (M1) or my Mac mini (intel)
Thanks - I do indeed live in the future - I'm in NZ which is GMT+13 at the moment (we're in summer time here) so timing was right. Regardless, I *think* the printer thought it was somewhere else as it does print now. Thank you. Your simple method worked - I'll make a note to adjust that printer timezone sometime in the next 10 years! :)
So much for the "Definition of Insanity" admonishment. Congratulations on that strategy. I guess I could try that approach also.
I did the same thing. This has never ever happened before. Should I go to the genius bar?
Thanks. That tip did the trick for me.
Well done everyone who contributed above. I am now, gratefully, back in the world of users whose printer works!!!!!
Had this message using an Epson printer. Your suggested remedy works! Brilliant. Thank you.
@Randall_2023, thank you. I was able to reinstall the printer, but I'm still getting the "encryption credentials have expired" message. 🙁
