With the OKI Microline 590, the decision is entirely yours. This letter-quality printer anticipates and conforms to all your paper-handling needs. The difference is OKISMART Paper Handling, a unique patented technology that allows the ML590 to 'read and learn' the paper you feed it, then set the head gap to the optimum distance for best print quality. It also means less time to load and reload paper stock, and can lead to longer printer life.
