Oki Microline ML3391 Printer Review

Expert review of the Oki Microline ML3391 printer 26 October 2015

Our Verdict:

The Oki Microline ML3391 is a wide carriage dot matrix printer ideal for different applications, including accounting and invoicing. It has a decent print speed on draft and is capable of delivering prints with near letter quality. Optional paper handling is available for the Oki Microline ML3391 printer. This model can only handle up to 4-part forms.


The Oki Microline ML3391 80 / 136 column dot-matrix printer measures 116 x 552 x 345mm and weighs 10.1kg. Its acoustic noise is 57dBA but on quiet mode it's 52dBA. Paper paths can be found on the top, bottom and the rear parts of the unit. Some of the optional paper handling available for the Oki Microline ML3391 24-pin printer include a push tractor, roll paper stand and cut sheet feeders. USB and parallel ports are provided.


Users can print different types of fonts and even use the built-in barcodes on the Oki Microline ML3391 mono dot-matrix printer. This model has a memory of 64kb and delivers a maximum resolution of 360 x 360dpi. It uses reliable components, including ribbon cartridges for boosted productivity and reduced downtime. The MTBF of the Oki Microline ML3391 black and white forms printer is 10,000 hours.


With a maximum print speed of 390 characters, the Microline ML3391 24-pin dot-matrix printer is pretty decent for small businesses or offices but will not be ideal for busier working environments. Multi-part handling is a bit limited at 1 original and only 3 copies.
