Microline 321 Turbo is a reliable, flexible 9-pin dot matrix printer, engineered with a printhead design that keeps print images sharp for a 200-million character life, built to stand up to harsh factory conditions, and is compatible with virtually all custom and "off-the-shelf" software. Also, designed with a lighter, stronger, more efficient motor that reduces friction, heat build-up and wear and a rack and pinion drive system that ensures print quality longer than belt or cable systems.
