Infrared (IR) Transmission
If your OM7212 is configured with the optional IR transceiver, it is capable of communicating via an IrDA 1.1 connection. To
determine if your printer is configured with an IR transceiver, print a test label as outlined in section 6 and look for the section
labeled “IR Port”.
8.2.1
Guidelines for IR Communication
Turn the printer on.
Place the host within 1 m (39 inches) of the printer’s IR port.
Make sure the host’s transmitter/receiver is within a 15 degree angle from the center axis of the printer lens. Please
refer to the drawing below:
