Hopefully the Brother printer is not connected to power outlet which is connected to an AFCI circuit breaker because it will trip it all the time. I had to move mine to a different part of the house for that reason.
Ours causes a "UPS is now on battery power" dialog to pop up every time it prints.[0] I have wondered if it would pop the circuit breaker if the UPS didn't buffer it, or if the UPS is just overly sensitive.
[0](Because the printer is on the UPS that has a USB connection to my desktop.)
I wouldn't put a laser printer on a typical consumer UPS. It draws a lot of current to warm up the fuser and may cause more wear than necessary to your line-interactive units. I always plug my laser printers directly into the grid.
I swear to god I was going crazy trying to find why I randomly tripped the circuit breaker at my house. I never made the connection that it actually happens when I try to print something. Enshittification indeed.
