Applies To

Zebra QL Series and MZ Series Mobile Printers



The IrDA specification that the mobile printers use is 1.1

IR communications:

    Printers equipped for infrared (IR) communications are identified by a small "IR" logo on the unit's label.  Those IR units that can also communicate with a cable (USB, serial) but one should note that IR functions are disabled when the cable is plugged in

    IrDA compliant terminals will automatically initiate communications to the printer. However, one needs to 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 printer must face the corresponding window of the terminal to properly send and receive signals.
