IR Communications
Printers equipped for infrared (IR) communications are iden-
tified by a small “IR” logo on the unit’s label. IR allows wireless
communications between the printer and the host terminal. IR
units can also communicate with a cable as detailed above,
however, IR functions are disabled when the cable is plugged
in. Printers with the IR option can be configured to conform to
the standard IrDA communications protocol
Linking a Printer to an IrDA Host
IrDA compliant terminals will automatically initiate communi-
cations to the printer. First 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. An IrDA compliant terminal will seek out any
linkable devices and establish communications between them,
even turning the printer on if necessary.
