Our take on the Lexmark MS431dn Duplex Monochrome

The Lexmark MS431dn is a monochrome laser printer built for small offices that need fast, reliable text printing. It prints up to 42 pages per minute, handles automatic two-sided printing, and connects over Ethernet or USB. It has no Wi-Fi and no color, so it is a workhorse rather than a home all-rounder. Its best new price is $329 at Adorama as of November 7, 2026, with 5 stores listing it new.
