The Lexmark MS331dn is a compact monochrome laser printer built for small offices and workgroups. It prints at up to 40 pages per minute, holds 550 sheets in its main tray, and prints on both sides automatically. A 1 GHz dual-core processor and 256 MB of memory keep busy shared jobs moving, and the steel frame with long-life imaging parts is meant for years of daily use. It is a wired-only machine: USB and Ethernet, no Wi-Fi. Against similar small-office lasers it stands out for speed and paper capacity, but it lacks a touchscreen, wireless printing and color.
