Printing costs

How we test printing costs

How cheap or expensive the printer is for ink/toner costs per page. More stars means cheaper prints. Costs are based on our occasional printing test - printing black text and colour pages, leaving time between prints and turning the printer off between uses. Printers with no star rating were tested prior to our occasional printing test.

Power use

How we test power use

For energy, it's based on power use when the printer is turned off, in standby and when idle, just after printing.
