Compact monochrome laser for small workgroups
The Lexmark MS431dw is a single-function monochrome laser printer rated at up to 42 ppm with a first-page-out time of 5.9 seconds. It delivers 2400 Image Quality at 600 x 600 dpi and supports automatic duplex printing. A 2-line APA LCD provides local status and menu navigation. Standard memory is 256 MB and the monthly duty cycle reaches 80,000 pages.
Verify network, paper and mobile requirements
Confirm your infrastructure includes Ethernet 10/100BaseTX (RJ-45) or a compatible wireless network for Wi-Fi connectivity. The printer accepts PCL 5c, PCL 5e, PCL 6, PPDS, PostScript 3 emulation, PDF 1.7 emulation and Direct Image print languages. Standard input capacity is 350 sheets across two trays, expandable to 900 sheets with a third tray. Output capacity is 150 sheets. Mobile printing uses the Lexmark Mobile Print app, Mopria, AirPrint and Google Cloud Print; ensure devices support these standards.
Fits tight spaces and scales with paper demand
Physical dimensions are 8.7 inches high, 14.5 inches wide and 14.3 inches deep, allowing placement on a desk or shelf. Two standard trays handle everyday volumes; adding the optional third tray raises maximum input to 900 sheets, reducing reload frequency during large jobs. Duplex printing cuts paper consumption for double-sided documents. The 150-sheet output bin collects finished pages without a separate stacker. Wireless and Ethernet interfaces let the printer serve multiple users without a dedicated USB host.

Questions about this item
Does the Lexmark MS431dw include a starter toner cartridge or must one be purchased separately?
The printer ships with a pre-installed starter toner cartridge so you can begin printing immediately; a full-yield replacement cartridge is sold separately.
Should I choose the standard 350-sheet input or add the optional third tray for 900-sheet capacity?
The standard configuration provides 350 sheets across two trays; adding the optional third tray raises total input to 900 sheets for larger workgroups.
What does the 42 ppm rating mean for everyday office use?
The 42 pages-per-minute speed applies to simplex A4/Letter black printing; duplex jobs run at roughly half that rate, and the first page appears in 5.9 seconds.
