IrDA Communication
All Mt3-II Series printers are equipped with an IrDA
interface. IrDA provides for wireless connectivity, but
does require a “line of sight” alignment between the
host computer and the IrDA window on the printer.

Bluetooth Wireless Data Communication
Mt3-II printers equipped with the optional Bluetooth Interface can communicate with a host that is compatible
with the Bluetooth wireless communication standard.
The Bluetooth data link functions wirelessly like IrDA,
with the important exception that no effort is required
to physically align the host and printer in any particular
fashion. If your printer is configured to use Bluetooth,
simply send the job from the host and tear off the
output – no other action is required.
Please refer to your host system’s documentation for
information on how to set it up to communicate with
the printer.
