Ironically, I have a printer that really needs a dedicated circuit. When it warms up the toner, it draws 12 amps for 1-2 seconds.

Printing often pops the breaker. I had to move the printer out of my home office into a bedroom, but even then we've popped the breaker when printing while vacuuming.

(It's not a case of bad wiring, either.)

There are types of fuses that have a time delay on them for this purpose. A lot of electrical appliances have that kind of startup burst of energy. An electrician can tell you more

Warming up the laser printer (and its a small one) reliably causes the lights throughout my apartment to flicker.

It's not an AFCI breaker, is it? My last house had sensitive AFCI breakers that my laser printer would trip about a quarter of time when warming up.

Yes, my electrician was going to change it for me; but then I plugged my printer into a kill-o-watt and learned that it was pulling 12 amps.

I've been assuming it was current, because if it has the circuit to itself, nothing trips.

(My office only has one circuit, which is dedicated to the room. I could have asked for 20 amps, but it didn't occur to me.)

I used to own a brother laser printer and it did this, I switched to HP LaserJet and this no longer occurs.
