IR Communications
Printers equipped for infrared (IR) communications are identified by a small “IR” logo on the unit’s label. (IR functions are disabled if a communications cable is used.) Printers with the IR option conform to the IrDA communications protocol.
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 communications 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.
