The Okidata Microline 521/n is a superior-performance wide carriage 9-pin impact dot matrix printer designed for multiple paper-handling applications, quality output and unmatched dependability. Featuring Okidata's OKISMART Paper Handling for hassle-free switching between different paper types. With OKISMART, the ML521/n "reads and learns," automatically adjusting to the paper you feed it. You get perfect output on single sheets, card stock, multi-part forms (up to six parts) and labels. Individual pins in the printhead also adjust to the changes in paper, so uneven printing, smears and light spots are things of the past. The ML521/n's paper loading is easy, and its jam-free paper path ensures uninterrupted throughput during long print runs. Also, the zero tear function of the optional Bottom Push Tractor lets you print on "difficult" media without wasting any forms. The printhead lasts longer, and the printer uses less power and works more efficiently. The ML521/n comes with an OkiLAN 6120e 10/100 Base-T internal print server pre-installed and ready to perform. Get handsome output and exceptionally fast throughput every time you print with the Microline 521/n.
