The Lexmark MX331adn is a monochrome laser multifunction printer for small workgroups that need printing, copying, scanning, and faxing. It prints up to 40 pages per minute, supports automatic two-sided printing, and connects by Ethernet or USB.
Recommended For
- Small offices printing roughly 500–5,000 pages a month, especially when staff share a wired network printer for black-and-white documents. Lexmark lists that as the recommended monthly volume and provides Ethernet connectivity.
- Workgroups that need one compact device for monochrome printing, copying, scanning, and faxing, with automatic two-sided printing for routine office documents.
- Teams that print frequent, text-heavy jobs and want a 50-sheet document feeder for scanning or copying one-sided batches without handling each page individually.
- Small businesses that want a wired office multifunction printer and do not require Wi-Fi: the MX331adn provides Ethernet and USB connections, and a community printer discussion considered it as a wired-LAN option for home and small-business use.
