Laser printers have a brief need for a very high amount of electrical power while heating the printing element. That has improved a lot, but was the basis for my comment that the lights would dim when using a laser printer in the past. Maybe the lights and plugs were on the same circuit, which is not up to code.
That suction needs a surge from the grid, so there could be a conflict between the printer and a surge protector, even though a small printer and healthy surge protector should be fine. Plugging into the battery supported side of a UPS would trip the alarm.
I haven't heard of printers going out from electrical surges like computers, but don't have problems with surges around here.
