In my experience, laser printers shouldn't be plugged into *UPSs*,
because the motor and heater spikes can damage the inverter output
transistors.  You might assume that transfer (rather than continuous)
UPSs wouldn't have a problem with this, but we have a little teeny
laser in our office plugged into a 3kVa APC, and that UPS *still* trips
on-line when the printer comes out of sleep.

Surge suppressors are entirely another matter, but I would bet that
'They' meant UPSs.
