Review: Canon Image Class MF249dw The Canon Image Class MF249dw is a smaller monochrome laser holding nothing back one printer that is a solid match (actually and metaphorically) for a home office or miniaturized scale office, or as an individual printer in any size office. It gives you a decent scope of availability decisions, adding Wi-Fi Direct to the USB, Ethernet, and Wi-Fi found in the Canon image Class MF227dw. The MF249dw likewise has a bigger programmed record feeder (ADF) than that model, and it includes support for the programmed filtering of two-sided archives.
