Hp HP LaserJet 4

Brother HL-2140--flickering house lights.

My room lights flicker anytime printer runs, its maddening. Tested multiple 15amp/20amp circuts in 4 yr old house, same result with all. Defective printer? Is this a problem with all the newer laser printers ( I've had an HP 6L for years with no such problem).
HP printers like the 6L use ceramic heating elements. They are low energy draw. The Brother printer uses a quartz lamp to heat the fuser. It draws close to 1KW. That's why your lights flicker.
