What affects a laser printer's wattage
A laser printer is rated around 500 W, but the real figure shifts with a few things:
- Model and rating: A laser printer ranges from about 300 W on efficient units to 800 W on larger or older ones — a spread of ~500 W.
- Usage: the real draw depends on the workload — idle browsing draws far less than gaming or rendering.
- Standby: even idle it keeps drawing ~5 W, which quietly adds up over a year.
- Run time: because a laser printer only runs in short bursts (a few minutes at a time), hours of use matter as much as raw wattage on your bill.
