If LP=Laser Printer: A laser printer can take a lot of power due to the 
heater. The heater in my Samsung ML4500 is 400Watts. If a power cut 
ocurrs while printing the UPS may fail unless it can take the heavy load.

BTW the reason I know the heater power is because I was stupid enough to 
print on non laser compatible OHP acetates, I ended up with the printers 
internals shrink wrapped! I took it to bits and had to remove the 
heater. The heater was a longer version of those halogen flood light 
tubes inserted into an aluminium tube. The heater has a connection tag 
at each end and at one end it had 230V 400W stamped into it.
