encryption credentials have expired message

A different/easier way to choose AirPrint instead of Secure AirPrint: in AddPrinter, hold the Option key down while selecting the printer - that should show both AirPrint and Secure AirPrint in the Use menu.

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.

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)

Why do you say this cert is valid? Unless you are in a timezone that has already reached Feb 9, 2023, this cert is not yet valid. It will be valid starting tomorrow though ... At the time of this writing, it is currently Feb 8, 2023 8:48am EST. This certificate will be valid from Feb 9, 2023 all the way up to Feb 6, 2033 ... So either you are patient and wait until tomorrow or re-generate a new certificate that's valid as early as today.

Firstly, I would update to 13.1 to see if that helps. If that doesn't resolve the issue, try this:

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.

@MamaShelz, did you try this method?

Mine is a WF-4630 also. Library is found in Finder>Locations>Macintosh HD>Library.

Be sure to download the new driver from Epson per the link Timystic cited.

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. 🙁

Nothing for Apple to fix, it's an issue with the printer's web SSL certificate. Check my prior post on how to resolve this in your Epson printer configuration.
