Laser printers use a brief high-power warm-up and much less power while idle. The number of pages and sleep settings affect annual use.
Typical sizes: 300 W, 500 W, 800 W, 1,200 W.
How to spend less: Enable sleep mode and print multiple pages per job when practical.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
