"Encryption credentials expired" 2020 Macbook Pro, Big Sur, Toshiba E-Studio3015ac

I can't print ever since the 11.2.1 Big Sur update! Only getting "encryption credentials have expired." I have attempted to delete and add the printer and change from "secure airprint," to "airprint," but the latter does not appear as an option. Any help is appreciated!

Hello P_Meg,

It sounds like you are having trouble printing after updating to macOS 11.2.1 Big Sur.

Here are some resources that might help: Review the additional steps in Solve printing problems on Mac

If you get to "Make sure you have the latest software" if Update printer software on Mac doesn't work, check out the drivers directly from Toshiba here Support: Drivers, Manuals, Tutorials | Toshiba Business. If you need help installing these drivers or have questions about them, contact Toshiba directly Contact Us
If you are wirelessly printing, to help rule out any network issues, try disabling any VPN or internet security software installed.

Hope this information helps. Have a good day.

Thanks!

Turns out it was an out of date encryption certificate (which may have been obvious). This was resolved by accessing the copier settings and updating it. It is now good to go for 99 months!
