HP Laserjet CP3505n uses 42W (or 48W) depending on which stats you read (not tested these). We also have Ricoh Aficio MP7001 which from testing comes in around 150W. The MPC2800 we have uses about 100W also. When in use, those 2 overload my meter, as they draw so much power.
Brother HL5250DN - 80W standby (according to specs).
Epson CX-11 - 51W standby, 18W sleep.
So, yeah, i'm working from those sort of figures.
