Powerful 9-pin dot matrix printers with
advanced paper handling

Fast, reliable, printing
for demanding work environments

The ML5720eco and wide carriage ML5721eco
are designed where fast printing, reliability
and flexible paper handling is essential. With
the ability to manage thick forms and heavy
works, these dot matrix printers are perfect for
demanding environments such as production,
vehicle repair/service centres, warehouses,
laboratories, wholesalers and freight forwarders.
Whether you are printing invoices, picking lists,
call log slips, tickets, receipts, forms or multi-part
documents, the ML5720eco/ML5721eco keeps
your transactions smooth and your customers

happy. And, thanks to the ML5720eco’s small

footprint it is ideal for businesses where space is
limited, for example, at the front desk of banks,
travel agents, stations or surgeries.

Flexible, Eco-friendly and cost effective

The ML5720eco/5721eco have been developed
with eco-friendly technology. With power

consumption of just 1.5w in Sleep mode, your

running costs and energy consumption are kept
to a minimum, as well as reducing your carbon
footprint.

More paper paths give you flexibility. The three
tractor feeding paths handle multi-part forms
and continuous paper from either the front, rear
or bottom. The two friction feeding paths handle
cut-sheets, cards and envelopes from either the
front or top.

A selection of pull and push tractors allow
permanent stationary loading, for use on demand
and handle multi-part and continuous forms
more efficiently. The optional Roll Paper Stand
(ML5720eco only) is a cost effective option for
applications with variable paper lengths.
