When you are using bluetooth to print labels from your Mobile WMS device, obviously both the printer and the scanning mobile device must have bluetooth switched on.
When you want to print a label the communication from the device is send to the MAC address of the printer. This setup does not require to pair the printer and scanning mobile device. The obvious advantage is that no paring is required.
Prerequisites:
1) In Mobile WMS Label Print you need setup the printers MAC address. See: Printer setup
2) Setup the printer to allow "unauthenticated encryption". Depending on your printer model and firmware there are various ways to setup this. Please go to your supplier of printer for guidelines to set it up properly.
