About laser printer running costs

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 in Washington. 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.
