The ML5520eco printer is suited to high speed, high volume data and word processing applications where fast throughput and flexible paper management are required. This 9-pin, narrow carriage, impact printer is engineered to be tough enough for dedicated printing in the most demanding environments. With outstanding reliability, ease-of-use and bar coding facilities and the ability to run twice as long as most printers in their class, they are ideal for supporting forms printing at customer service points in wholesale and service environments. The ML5520eco has been developed to be eco-friendly at a CarbonZero manufacturing site. With power consumption at just 1.5W in sleep mode, your running costs and energy consumption are kept to a minimum, as well as reducing your carbon footprint. The ML5520eco can accommodate multipart forms and stock that are up to twice as thick as those that fit our nearest competitor. Their relentless performance comes from OKI's unique, high durability printhead design; and a light, strong, efficient motor. The long-last rack-and-pinion drive system and a protective, impact-resistance chassis, make it resilient to even the toughest environments.
