The ML3320eco and wide carriage ML3321eco 
printers are suited to high speed, high volume 
data and word processing applications, where 
fast throughput and flexible paper management 
are required. 

These 9-pin, impact printers are engineered to 
be tough enough for dedicated printing in the 
most demanding environments. With outstanding 
reliability, ease-of-use and barcoding facilities 
as well as the ability to run twice as long as 
most printers in their class, they are ideal for 
customer service points in wholesale and service 
environments.  

The ML3320eco/ML3321eco 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 even 
in the toughest environments 

With a patented optical sensor that places the 
printhead for precise output, and the auto-tear 
feature that accurately positions your continuous 
forms for a clean tear, right at the perforation - 
eliminating wasted forms and facilitating your 
day-to-day forms printing.

The ML3320eco/ML3321eco have been 
developed to be eco-friendly. With power
