Mini Bluetooth Printer Printing Status Monitoring
How to monitor printing request is succeed or not? To acheive this function, we can help to make a shakehands protocol between your software and printer.
After the Bluetooth connection is successful, send the printing data to to the printer. At this time, add the command of "****" at the end of the printing data each time.
When all the data is printed out normally and the printer receives this command, the printer returns a "success" to the APP, which indicates that the printing is successful.
If the APP does not receive the returned data within 5 seconds after sending the data, it means that the printing has failed, and the APP needs to prompt to check whether the printer is working normally or the Bluetooth connection is succeed.
