OKI Microline ML521 Printer Review

Expert review of the OKI Microline ML521 printer

Our Verdict:

The Oki Microline ML521 is a specialised forms printer that automatically adjusts to paper thickness, whether printing a single sheet form or multi-page forms up to six parts. The device is equipped for printing on various types of media, including labels and envelopes, single part forms, as well as cut sheets and even carbonless multi-part continuous forms that creates up to 5 copies and one original. The Oki ML521 forms printer is a versatile device that allows efficient forms printing and quality document processing. However, the Microline ML-521 impact printer lacks network connectivity and it is not suitable for high quality graphics printing.


Designed for high quality impact dot-matrix printing, the Oki Microline ML521 dot-matrix printer features a 9-pin printhead, which automatically adjusts according to the type of media used. It is designed for high speed draft printing, capable of producing as many as 427 characters per second. The Oki Microline ML521 matrix printer features a parallel port as standard interface, and it produces quality prints up to 144x288 dpi in resolution.


The Oki Microline 521 printer boasts a receive buffer memory of up to 64K, and it features a good list of print quality fonts. Its printhead lasts up to as many as 200 million characters on average and the unit can process media of varying thickness. The ML521 Microline ribbon printer measures only about 43.1x38x16.6 cm, small enough for a desktop setup. The black Oki ML521 ribbon is easy to replace and comes with a large print yield of 4 million characters.


On the other hand, the Oki ML521 Microline dot-matrix printer does not offer versatile connectivity, and it cannot be shared over a network of users, due to its lack of an Ethernet connection.
