Built in the Tank Tough® tradition of OKI printers, the new Microline® 320/321 Turbo/D improves on its heritage. Now engineered for dedicated forms printing in DEC ANSI environments, this 9-pin dot matrix printer is economical enough to put wherever you need data on the spot. The ML320/321 Tubo/D puts the ""work"" in workstations. Its relentless performance comes from a rugged printhead design. A lighter, stonger, more eficient motor. A long-lasting rack-and-pinion drive system. And a protective, impact-resistant chassis. The printer can accommodate 6-part forms and thicker stock due to its expanded head gap feature. The printhead delivers a stonger punch — right to the last page of a multi-part form. A patented optical sensor accurately positions your continuous forms for a clean tear right at the perforation, eliminating wasted forms.
