IR Communications
Printers equipped for infrared (IR) communications are iden-
tified by a small “IR” logo on the unit’s label. Printers with the
IR option conform to the IrDA communications protocol.
IR functions are disabled if a communications cable is plugged into
the printer.
Ensure that there is a direct line of sight between the printer
and the terminal that will be sending data. The IR window on
the front of the printer must face the corresponding window
on the terminal to properly send and receive signals.
IrDA compliant terminals will automatically initiate communi-
cations to the printer. An IrDA terminal will seek out any link-
able devices and establish communications between them,
even turning the printer on if necessary.
