Printer sharing of Brother HL-2140 does not work on Big Sur
Printer sharing of my Brother HL-2140 stopped working when I upgraded Big Sur to 11.6.7. I have set Printer Sharing set ON for the 2018 MacMini running BigSur 11.6.7 to which the printer is attached, on my 2017 MacBookAir running Big Sur 11.6.7 (which is not attached to a printer), and to my wife's 2009 MacBook Pro running El Capitan 10.11.6. Both of them were able to print using the shared Brother printer before I installed 11.6.7; neither of them do now. I can print from the MacMini to which the printer is attached, but not from either of the two other computers on my wireless network. Any ideas what might work?
Mac mini, macOS 11.6
