Full-spectrum security
Lexmark's comprehensive approach to product security is a design and engineering mandate across our entire product portfolio. Our security features help keep your information safe—in the document, on the device, over the network, and at all points in between.
Hands-off durability
With its steel frame and lifetime fuser, the MS331dn is built to last.
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).
