I guess a Laser Printer (and definitely a refrigerator) draws a LOT of current when the electrical motor starts rotating. If I remember right from the Physics classes I took in High-School, some electrical motors require 10 times the nominal current at start up.
You also don't want to connect Fans or other such appliances on UPS.
EDIT: I am not sure if the laser printer draws high current because of the motor or perhaps some heater to make the toner stick to paper???
