OK so I just got a new MAC Mini and transferred everything over from an iMAC Pro, which is being retired and sold. I tried printing with my old trusty Brother HL-2270DW and got the "Stopped - Filter Failed" message. Did some research and saw some really egghead type posts that talked about deleting files in the root directory and even provided new code to install. Yeah - no way man, that is a highway to making things worse - at least for me.
So here's what i did an it works perfectly again - although I am using a USB cable.
1) First, I went to Brother and Downloaded (but did not install right away) the original printer driver. Note - the latest driver was for MacOS 10.15, my new MAC-Mini is Sonoma 14.5, but I was like "whatever, let's give it a shot".
2) Then I went to System Settings => Printers & Scanners => Clicked on the Printer => Remove Printer.
3) Backed out of Settings and reinstalled the 2270 Driver.
4) Then I went back into System Settings => Printers & Scanners => Made sure all the properties were the way I wanted.
That's it! Works fine again over USB.
In terms of printing over WiFi. I use Brothers iPrint&Scan App on my iPad - and prior to the new Mac-Mini it also worked perfectly over WiFi. but now it doesn't, so there is still a Network handshake issue to figure out, but now that it is working through the Mac-Mini, I'm not too worried.
