desk printing
For fast, reliable, superior quality printing in
retail and service industries and all types of
invoice and order printing applications
The ML5790eco and wide carriage ML5791eco
are ideal where fast printing, reliability, versatile
paper handling and superior quality text is
essential. Whether you are printing invoices,
purchase orders, spreadsheets, picking lists,
call log slips, tickets, receipts or multi-part
documents, the ML5790eco/ML5791eco keeps
your transactions smooth and your customers
happy. The small footprint of the ML5790 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 eective
The ML5790eco/5791eco 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 exibility. 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
eciently. The optional Roll Paper Stand
(ML5790eco only) is a cost eective option for
applications with variable paper lengths.
