With the Okidata Microline 590/591, 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 ML590/591 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. The ML590/591 delivers perfect output on letterheads, card stock, forms with up to 5 parts, and labels. And, unlike ordinary printers, the ML590/591 takes on envelopes like any other paper media. Just feed them into the printer and they emerge flawlessly printed, with no jams or smears. All this and a talent with color, too: an optional, user-installable Color Kit for the ML590/591 coupled with your color software package lets you work in a rainbow of colors, adding impact to graphics, charts, transparencies and text presentations.
