When you connect the printer Bluetooth to your Windows PC, it does not succeed and reminds you to reconnect.
Reason: You connected to the wrong printer.
Solution: Please connect to the printer with the printer icon, not the computer icon.
( please choose your printer name, such as Label_printer_XXXX)
If you cannot find the printer icon, delete the driver you have installed and reinstall that driver. You will then find a printer icon for your printer.
