alt Hacker NewsThey've done something with the printer system in Tahoe. Brother removed support for native drivers on certain label printers on Tahoe (!!!) when you go searching you find other printer issues.
Like, why. Why would you need to change the printer system? It works.. has worked for a very long time, there's no reasonable need to change it.

They overhauled CUPS and replaced chunks of it.
Oh man! I came here to complain about printing! I just discovered yesterday that you can no longer drag and drop print jobs from one printer to another. Apparently you can move a print job via some command line stuff but it just ended up deleting the jobs entirely. The only reasons I found this out is because the printer which had been working fine moments before just stopped working after replacing toner. No amount of deleting and re-padding the printer or power cycling either machine fixed it. One time the whole OS just froze and I had to force reboot. I spent a good chunk of the afternoon trying to get one 3 page document to print. To be fair, I haven’t had problems with this setup for 10+ years but when it went south it also went to the remote frigid corners of Antarctica.
This might've been a side effect of removing support for third-party kernel extensions rather than something changing with the printer system specifically.
I have an old (~10 years old) printer that Cannon stopped supplying updated macOS drivers for several years ago. The installer for the drivers failed so I had to extract the files from the package and install them manually. In the end only the network drivers work, the USB drivers are kexts which won't run.
