Technical summary: if you need to reconnect your Bluetooth label printer, make sure you use the "forget device" option from the Bluetooth settings on the iPad.
BEFORE YOU SETUP YOUR PRINTER
Apple iPad devices will require you to allow discovery of the printer on the network, either WIFI or Bluetooth. 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.
Note: Bluetooth printers can only connect to one iPad at a time. You will not be able to connect multiple iPads to one printer when using the Bluetooth option.
If your printer stops working or looses connection you need to reconnect the printer to your iPad but first, you will need to un-pair it from the Teamgo App and the iPad itself.
1. Check to ensure the Bluetooth printer is not paired with the Teamgo app. Login to your Teamgo application and view Printer Settings.
2. Check your iPad's settings app, if the Bluetooth printer is still showing as connected, select it and tap the Information (i) icon.
