I also own a Brother printer since I ragequit HP last year. While playing with the settings last week i manually checked the firmware and noticed a possible update. When searching online for the release notes, i found thread after thread of people wanting to revert the update because it blocked third party toners? I hope Brother doesn’t go the HP way…

I tried a couple of times already, but always feel it’s not quite ready yet… Games not starting or running slower, etc. Running latest Ubuntu, Wayland and new PC with an RTX4060ti. What am I doing wrong?
