I did the 11.6.7 update yesterday, today I discovered nothing would print from my M1 MacBook Air. All apps, using both (older) printers would fail with a “Stopped - Filter failure” warning in the print queue. Tore my hair out for 2-3 hours trying to troubleshoot, the biggest problem being that there is no simple way to roll back to the previous OS version. Back in the good ol’ days I’d just pop in my backup HD that I do before any software update and duplicate the data & OS back onto the laptop but that’s no longer possible. (Please, tell me I’m wrong!) Printing was working fine using an older MBP/OS 10.13.6 so I knew the network & printers were not the problem
Among the things I tried was resetting the printing system and re-adding the printer drivers. The Brother MFC-7360N seemed to add OK, but still wouldn’t print from any app, same failure. The Canon MP490 failed to add–“Could not communicate with the printer.”
Long story short…I happened to click on the Scan button in the Brother print queue and got a dialog asking if I wanted to install Rosetta to use the “older software” in my system. Uh, sure. And that was the fix.
Does that mean that the 11.6.7 update left out Rosetta? I don’t know, but hoping this is helpful to other Big Sur users that encounter printer “Filter failure.”
