Our take on the Lexmark MX331adn Duplex Monochrome Laser

The Lexmark MX331adn is a monochrome laser multifunction printer that prints, scans, copies and faxes, with automatic two-sided printing and a 50-sheet automatic document feeder. It connects over Ethernet or USB and handles Letter, Legal and A5 paper. Its best new price is $399 at Adorama as of November 7, 2026, with five stores listing it new. That sits at the top of its recent range, so it is not a bargain moment.
