MS421DW

Untethered printing defines the Lexmark MS421DW, the wireless twin of the MS421DN that drops its Ethernet cable for flexible placement anywhere with a Wi-Fi signal. Away from the wired network closet it still pulls duty as a full-speed mono printer with automatic duplex, drawing from the same 561H high-yield cartridge family. Ideal for open offices, retail back rooms, and spaces where running cable is not an option. The entry cartridge in the range is the 56F1000 black toner, which delivers around 6,000 pages per unit.

Cartridge	Color	Page yield

561H (56F1H00)	Black	~15,000 pages
561X (56F1X00)	Black	~20,000 pages
