The Canon i-Sensys LBP621Cw is a single function color printer for a small office or for a home office if you don't need a scanner and copier. Single function means printing only. This laser printer can print single-side prints with a print speed of 18 pages per minute. Set up a pin code to protect your printer against unwanted guests and print wirelessly via WiFi. You don't need a router for this. Thanks to the paper capacity of 250 pages, you don't have to refill often. You can adjust the settings on the 5-line color LCD screen. You can easily control this via the physical buttons.
