By default, the QL-820NWB must be powered on by manually pressing the power button. If you have set up your printer as per our guide Brother QL-820NWB Badge Printer Setup you have automatically disabled the "Auto Power Off" function.
An additional function is also available to automatically turn the printer on once power is restored, say after a blackout. To enable this feature you either need to connect the printer to a Mac or PC for a one-time settings change or connect your printer over WiFi and browse to the printer's IP address to access the Web Configuration Utility.
Important:
Although "Auto Power On" or "Power On When Plugged in" is set to On in the Printer Setting Tool or web configuration utility, the printer may not turn on immediately when power is restored.
Due to the energy-saving design of the circuits, the printer requires some time before it turns on automatically after you plug the printer in again soon after unplugging it.
