When the prompt appears, you will need to allow the device to discover connected devices like the printer. Accept this to Allow Always and you can proceed with the connection process outlined below.
Fixing a disconnected Bluetooth printer (Brother QL-820NWB)
There may be a few reasons your printer stops working including an actual hardware fault. While this is rare, the more common reasons are listed below and the same solution we provide will work for all of them.
You have a new iPad you need to setup
You have a new printer you need to connect
You have disabled Bluetooth
You deleted and re-installed the Teamgo app
The Brother QL-820NWB printer offers Bluetooth connection direct to the iPad, this means you do not need to connect the printer via WiFi. You can create a direct connection between the iPad and the Printer.

3. Tap "Forget this Device"
Now reconnect your Bluetooth printer to the iPad following the instructions provided in our Printer connection articles for Bluetooth connection.
