Oki Microline ML5721eco Printer Review

Expert review of the Oki Microline ML5721eco printer

Our Verdict:

The Oki Microline ML5721eco is a dedicated forms printer, excellent for managing different kinds of forms and invoices. It is best for inventory applications, as well as for printing out picking lists, tickets, call log slips, forms, receipts, as well as multi-part documents. The Oki Microline ML5721eco dot-matrix printer leaves a small footprint making it ideal for use in any kind of environment, even in small workspaces like front desks and checkout stations. However, the wide carriage Oki ML-5721eco printer may not be of great use elsewhere, as it is especially designed for printing specific types of documents.


The Oki Microline ML5721eco has an eco-friendly design, which sets it apart from its competition. The entire machine consumes only 1.5W when in sleep mode and the unit comes from a carbon-zero rated facility. The Oki ML5721eco Microline printer keeps running costs low and energy consumption is kept at a minimum, generally reducing your carbon footprint. The Microline 5721eco forms printer is also designed with several paper paths for handling different kinds of forms and media including cut sheets, envelopes, and even cards.


The Oki Microline ML5721eco 9-pin dot-matrix printer increases productivity, as it can print as many as 7-part forms at impressive rates of up to 700 characters per second. The ML5721eco printer is easy to install and it leaves a very small footprint, ideal for small workspaces. Ribbon changing is simple and infrequent, as Oki ML5721eco ribbons typically last up to 13 million characters before needing replacement.


On the other hand, the Microline ML5721eco machine is not as versatile as other dot-matrix printers, as it can only process forms and similar types of documents.
