Lexmark MS431DW Desktop Wireless Laser Printer - Monochrome

Light, compact, and fast, the MS431dw supports output up to 42 pages per minute, wired and wireless connectivity, and an optional 550-sheet paper tray.

Save paper, save energy

Automatic two-sided printing is standard, along with built-in energy-saving modes that help support ratings of EPEAT® Silver and ENERGY STAR® certified. The Lexmark Cartridge Collection Program (LCCP) and Lexmark Equipment Collection Program (LECP) minimize waste and support recycling (availability varies by country).

Output that fits

Measuring just 8.7 inches high x 14.5 inches wide x 14.3 inches deep (222 mm high x 368 mm wide x 363 mm deep), the business-class MS431dw fits almost anywhere. Its compact size and light weight make it easy to set up and easy to move.

Print more, stop less

In addition to a first page as fast as 5.9 seconds and output up to 42 pages per minute*, available Extra High Yield Unison™ toner provides up to 20,000 pages of output. Add an optional paper tray that increases total input capacity up to 900 sheets for more printing and less downtime.

Flexible connectivity

In addition to Ethernet and USB, built-in Wi-Fi makes it easy for mobile users to get output via the Lexmark Mobile Print app, as well as Mopria®, AirPrint and Google Cloud Print. And the Lexmark Mobile Assistant app simplifies wireless configuration.
