Printers equipped for infrared (IR) communications are identified 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. QL 320 units 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 communications to the printer. First insure 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 QL 320 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.
