Lexmark W850dn

Features

Serious Printing Performance

Reach your true productivity potential with Lexmark's most powerful monochrome laser printer with duplex standard. You'll get powerful 800MHz processing and 256MB of RAM standard, with print speeds up to 50 ppm and the time to first page print as fast as 6 seconds, plus fast Gigabit Ethernet.

Exceptionally Versatile

From start to finish, designed to handle your toughest tasks―from hard-to-print media to paper sizes up to A3. Optional accessories let you easily expand your input capacity up to 5,100 sheets or add finishing touches with stapling, hole punch and offset stacking.

Ups Uptime

Combines reliable high-speed printing with must-have features like Job Waiting to keep the print queue flowing and Direct Web printing for on demand printing of online documents. Plus a solutions-ready framework for tapping into serious business apps that can help you save paper, cut waste, lower costs and enhance document security. See Related Links to learn more.

Cutting-Edge Security

From network security to user-access restrictions, you’ll be fully equipped to keep valuable data safe and sound. In addition to IPSec, SNMPv3 and 802.1x network security, the Lexmark W850dn offers an alphanumeric pad for easy PIN authentication, plus encryption and disk wiping to secure the optional hard disk.

An Easy Operator

Easy operation, including a four-line display that provides intuitive visuals to guide users. Duplexes automatically―no reinserting sheets manually to print the second side. Plus a convenient front-side Direct USB for printing PDFs and other image file types directly from portable memory devices.

Prints Black. Thinks Green.

Eco-conscious features include built-in duplex printing to save paper, Eco-Mode to save energy, and Quiet Mode for ultra-quiet operation. Recycle your empty cartridges free of charge through the Lexmark Cartridge Collection Program (see Related Link to learn more).
