It's always been my understanding that plugging a computer into the same
circuit as anything that suddenly draws a lot of power (like a laser
printer when it fires up the fuser or a space heater) is a no-no.  

Those devices cause momentary power dips and spikes as the go on and
off, and that can absolutely kill your system.

If you have any way to condition your power (I believe that some UPSs do
line conditioning as well) you probably should.
