5.Double-click the downloaded .exe driver file and follow the prompts to complete the installation.


6.When the printer selection page appears, select Bluetooth and click “Next” to continue the installation.

7. Click “Next” to continue the installation. The program will search for nearby Bluetooth devices, which will take approximately 30 to 60 seconds. No action is required during this process; simply wait until the new interface appears.

8. When the device selection interface pops up, select the corresponding A812Bprinter and click “Next” to complete the installation.


9. Open Settings, click Printers & Scanners, and find “A812B Label” in the list. This indicates that the printer has been successfully installed.

10. Note: After installation, two A812B options may appear in the system print list. One of the options may display “Driverisunavailable.” This is because USB and Bluetooth printing methods handle print jobs differently. This is normal and requires no action.
