Possibly because some laser printers have 1000 watt fusing elements
and most home UPS units can't provide that much power?

They go out of their way to hide it. A friend of mine moved here with a 120
volt industrial strength HP laser printer. The specs said 325 watts, the
current draw was listed as 8 amps max on the last page of the manual.

My current small Samsung printer never actually says what it draws, but the
web page and manual made a big point about it drawing 6 watts in standby. Since
we print around 5 times a week, the standby current matters more than the
max draw, but I would not want to plug it into a UPS.
