The Canon imageClass LBP622Cdw is an in-color laser printer intended to be used in a home or small office. Although it is a simple, no-nonsense machine, overall it prints well and is small enough to fit in cramped spaces. Works with the macOS and Windows. The principal paper tray has a capacity of 250 sheets, a generous size. It can tolerate up to a base weight of 55 # of paper, heavier than what is usual. There is a second tray for full-size paper which allows you, for example, to load letterhead paper.
