Lexmark MS331DN 29S0000 Desktop Laser Printer - Monochrome - 40 ppm Mono - 2400 dpi Print - Automatic Duplex

The Lexmark MS331DN is a monochrome laser printer with automatic two-sided printing, suited to small offices and workgroups that need regular black-and-white document printing within a recommended monthly volume of 500–5,000 pages.

Recommended For

• Small offices printing several hundred to about 5,000 pages a month of black-and-white documents, such as invoices, forms, and reports; its recommended monthly volume is 500–5,000 pages.
• Workgroups sharing a printer over a wired office network who want fast monochrome output and automatic two-sided printing; the MS331dn supports Ethernet, prints up to 40 pages per minute, and has integrated duplex.
• Home-office or desk-based workers who regularly print text-heavy documents and can connect the printer by Ethernet or USB rather than relying on Wi-Fi.
• Users who mostly print plain paper but occasionally need labels, envelopes, or card stock; Lexmark lists these media types as supported.

Real-World Use Scenarios

• In a small office, staff can print routine black-and-white reports, forms, and correspondence from a shared wired printer; a professional test found text printing reasonably quick, though mixed graphics jobs may take longer.
• For everyday office paperwork, users can print multi-page documents on both sides without manually turning the pages, helping reduce paper use and finishing steps.
• In a home office that regularly prints contracts, invoices, or other text-heavy documents, the MS331dn provides black-and-white laser output without taking up much desk space.
• A small team can connect computers to the printer over Ethernet for shared office printing, or use USB when it is set up for one nearby computer.
• For occasional office mailing or product-label tasks, users can feed supported envelopes or labels through the multipurpose feeder and print them in black and white.
