Hi Gene,

Not sure if CUPS debugging may be helpful, see eg.

https://sysadminera.com/2020/09/10/linux-how-to-enable-and-capture-cups-debugging-logs/

But first, I seem to recall you removed avahi and cups-browsed from Bullseye machines.  Is that correct?  Do the Buster machines have either or both of those installed?

What are the exact models of the Brother printers "missing" from Bullseye systems?

Do other printers appear on Bullseye systems?  

Thanks,
Gareth
