Brother printers, from my experience, will just work automatically -- depending on your distro. If you need drivers, they do have a Linux installer as well. I've used the installer before and definitely not even a fraction as scummy as Canon/HP driver installs.

Pretty much every printer released since 2010 has IPP Everywhere support, which allows for driverless printing on any platform including Linux.

What about scanning?

I can't speak to every Brother MFC, but mine just appears as an option in any application supporting SANE.

There's IPP driverless scanning, as well.

These understand standard PCL (and even PDF, somewhat) - you really only need to point CUPS at the printer's IP and tell it what the page size is.

Can't speak for OPs printer but my brother just uses IPP and a PPD definition file, all supported out of the box with cups.

My printer works on a framework laptop with Fedora 35 with absolutely no configuration, or any installations of any kind (beyond having connected to the wifi).

Ironically, my windows desktop won’t print to it though. It just reports an opaque error sending to the print queue with no diagnostic information. No idea if it’s a windows problem or a printer problem, because I just use my linux laptop to print with no issues, so I haven’t bothered to resolve the windows printing issues.

I had trouble geting a dirt cheap Brother running with CUPS and FreeBSD. Their official Linux PPD did some funky ghostscript+custom scripts thing that didn't translate to FreeBSD. I got it working with a OpenPrinting PPD instead.

Yes and it works out if the box in any modern distro.
