OKI Microline 5721eco in More Detail

The wide carriage ML5721eco dot matrix printer delivers fast, reliable multi-part forms printing all at low running costs.

Impressive speeds and productivity

With high 700cps (characters per second) print speeds, fast throughput and ability to manage heavy medias, make them perfect for demanding environments such as vehicle repair/service centres, warehouses, factories, wholesalers and freight forwarders.

Ideal for high duty applications, printing receipts, invoices, picking lists, reports or spreadsheets, on single or multi-part paper, the ML5721eco printer will keep productivity levels high. And with multiple emulations, replacing slow or failed printers is simple and straightforward.

Low cost consumables

The long life 24-pin print head delivers high quality documents on single or multi-part paper, printing up to 7 copies simultaneously.

And the addition of ‘Clean hands’ ribbon changing, the dot matrix printers ribbons also last up to 13 million characters – keeping running costs to a minimum.

Versatile paper handling

The ML5721eco printer can also feed both cut sheet paper and continuous forms with ease. Front, top, bottom and rear paper input paths and anon-board tractor feed unit that can be front or rear mounted provide truly versatile paper handling.

Optional push and pull tractor units are available to allow the loading of two different media types simultaneously or the feeding of heavier papers and labels. A Roll Paper Stand option is available for the OKI ML5721eco for economical printing of passenger lists, call logs, data logs and more.
