The Fast Ethernet-ready Lexmark E450dn creates professional, high-quality documents at a print resolution of up to 1200 x 1200 dpi on a range of media. The Lexmark E450dn with its 400 MHz processor, can process documents at a print speed of up to 35 ppm and a time to first page of as fast as 7 seconds. Its 64MB of standard memory, integrated 250-sheet paper tray and optional 550-sheet drawer add flexibility to the Lexmark E450dn. A true rarity for an integrated duplex printer, the Lexmark E450dn mono laser is remarkably small, fitting easily on tiny desktops and in tight workstations. Network-ready and easy to set up, it features an intuitive all-points-addressable 4-line display to coach you through printing and maintenance tasks step by step. In addition to all the savings you'll make with two-sided printing, you can also opt for high yield cartridges to lower your printing costs even more. And when it's speed you need, you can count on 64MB of standard memory to help you zip through print runs at up to 35 ppm (33 ppm A4).
