Hi,
Does your light dim when your fridge kicks in or you use mirowave oven,
etc.? UPS = uninterrupted power supply, what makes you think UPS is
helpful? Maybe your place's wiring is at the borderline approaching max
capacity and that extra load printer is it. Laser printer has
fuser(heater which draws some current when printing).

Hi, no my fridge and microwave don't cause the lights to dim. In the
bathroom, the hair dryer does cause the lights to dim but only in that
room.

My rational for the UPS solution was that since the printer runs at
450 watts when printing, then, say a 600 watt (1000VA) UPS battery
would act as a buffer during the high load times. Doesn't this make
sense?
