New HP, new Mac does not print

[BrutalMoose]

HP 8020 2022. Mac Apple Silicon Ventura newest version. For several months, it will say The Encryption Credientials have expired. I factory reset printer, it works, I can print and scan. Then months later it comes back, over and over. This error has come back 3 times. Using WiFi connection, not USB cable. I have tried so many solutions on so many websites that I cannot remember them all, and they did not solve the issue. This is a new Mac installation, from about January 2023, clean install, not a migration, so all fresh Macos and Macos-Printer settings. A home user does not need this high of security, how do I permanently remove this error forever. Thank you.

You can try removing the Info.plist (Property list) file of the Printer software.

That error is being generated because the printer uses https for airprint. The certificate for the secure connection is expired. Here’s a link to a support page at HP explaining how to generate and install a new certificate. Unfortunately it appears it requires a windows machine to generate the certificate, but the new cert will last 10 years.
