Lexmark MS431dw
Small offices that need a fast mono printer on Wi-Fi

The MS725dn is built for volume: a 55 ppm engine, a 150,000-page imaging unit and a 55,000-page cartridge give it some of the lowest cost-per-page figures in the A4 mono market. It is a large, heavy printer more at home in a print room than on a desk. Owners should budget for a maintenance kit (fuser, transfer roller and pick rollers) around the 200,000-page mark.

Best for: Print rooms and departments needing very high mono volume at low cost per page
Network configuration is done through the Embedded Web Server after reading the IP from the Network/Ports menu; set a static address there because print servers dislike DHCP changes. Use the Lexmark Universal Print Driver and enable any optional trays or finisher in the driver's configuration tab. Because it is a shared high-volume device, set up supplies notifications by email so the 55,000-page cartridge does not run dry unnoticed.
The Lexmark MS725dn uses the following consumables. Match the number exactly when you buy: the same printer family often uses several different cartridge numbers by region.
High-yield (XL) versions almost always cost less per page if you print regularly. On third-party ink and toner, read our honest assessment first, and note that some manufacturers push firmware that rejects non-original chips.
