Power consumption
Although costs are discussed, electricity consumption is not, and it can be very significant as shown below. Consumption is very dependent on how much the printer is used and the annual TEC (typical energy consumption) figures below are based on printing for 1 hour per day, five days per week for 52 weeks per year on a typical UK electricity tariff. Where possible, figures come directly from http://www.sust-it.net/ .
