Discover Printers - Select your preferred discovery method.

Wi-Fi and Ethernet Network

Bluetooth Classic

Bluetooth Low Energy

USB

For successful network discovery, ensure your device is connected to the same subnet as your printer. For Bluetooth communications, ensure that Bluetooth is enabled on both your device and printer. Refer to the user documentation for your device or printer for further details on configuring the printer and device.

Bluetooth discovery can only retrieve the Friendly Name and MAC Address.

If you encounter issues with printer discovery (and at times when

Zebra Nucleus Connector

may not be able to discover your printer), you may need to manually enter your printer’s IP address. Having your printer and device on the same subnet gives you the greatest chance of successfully discovering the printer.

Starting with Link-OS v6, the

bluetooth.discoverable

function is now off by default, and other devices cannot see or connect to the printer. With discoverability disabled, the printer still establishes connections with a previously paired remote device.

Enable discoverable mode only while pairing to a remote device. When paired, discoverable mode is disabled. Starting with Link-OS v6, a new feature was introduced to enable limited discovery. Holding down

for 5 seconds enables limited discovery. The printer automatically exits limited discovery mode after 2 minutes have elapsed, or a device has successfully paired with the printer. This enables the printer to operate safely with discoverable mode disabled until a user with physical access to the printer activates it.

Upon entering Bluetooth Pairing Mode, the printer provides feedback that the printer is in Pairing Mode using one of these methods:

On printers with a

Bluetooth Classic,

Bluetooth Low Energy screen icon, or Bluetooth/Bluetooth Low Energy LED, the printer shall flash the screen icon or LED on and off every second while in pairing mode.

On printers without a

Bluetooth Classic or Bluetooth LE screen icon or Bluetooth Classic or Bluetooth LE LED, the printer shall flash the Data icon or LED on and off every second while in pairing mode.

Specifically, on the ZD510 model, the 5-flash LED sequence activates Bluetooth Pairing Mode.
