Their high 576 characters per second (cps) print speeds, fast throughput and ability to manage heavy medias make them perfect for high duty applications where presentation and print quality are essential. And with multiple emulations, replacing slow or failed printers is simple and straightforward.
Ideal for printing customer facing documents such as receipts, invoices, dispatch notes and spreadsheets, on single or multipart paper, the ML57901eco will keep productivity levels high and document presentation professional.
A versatile machine
The ML57901eco printer, can feed both cut sheet paper and continuous forms with ease. Front, top, bottom and rear paper input paths and an on-board tractor feed unit that can be front or rear mounted provide truly versatile paper handling.
Optional push and pull tractor feed 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 ML5791eco for economical printing of passenger lists, call logs, data logs and more.
Low running costs
