Knowing the Bluetooth address of the printer is crucial for connecting mobile devices to the printer via Bluetooth. There are several ways to check the Bluetooth address of the printer.

　　One common method is to check on the printer's self - test page. Usually, there will be information such as "Addr", "EDR ADD", "Bluetooth addr", or "Address" on the self - test page, followed by the Bluetooth address of the printer. To print the self - test page, you can refer to the method described above. This is a relatively simple and direct way, as long as the printer's self - test page function is working properly.

　　If the Bluetooth address is not found on the self - test page, you can use a mobile app or software tool to check. For example, on a smartphone, you can install a Bluetooth - scanning app. After opening the app, it will search for nearby Bluetooth devices. When the printer is detected, the app may display the device's details, including the Bluetooth address. On a computer, there are also some Bluetooth management tools that can be used to view the addresses of connected or discoverable Bluetooth devices.

　　Another way is to check the printer's user manual or the manufacturer's official website. The product documentation usually provides detailed information on how to find the Bluetooth address of the printer, including specific operation steps and screenshots. If you can't find the relevant information in the manual, you can visit the manufacturer's official website and search for the product support page. There, you may find answers to frequently asked questions or technical support documents that mention how to check the Bluetooth address.
