If it’s not a GFCI or AFCI protected circuit then it has to be overcurrent or a bad breaker (they do stop being able to hold over time).
For overcurrent, something isn’t right with your PSU and it’s drawing more than 15 amps or 20 amps if yours is in the kitchen.
For a bad breaker, put your printer on a different circuit and see if it continues to trip. If not, swap the offending breaker out. Pretty safe to do yourself if you don’t touch the bus bar behind the breakers (otherwise it WILL kill you).
I thought the same but my wife actually is indifferent to it for the most part. What she does like is message backgrounds.
