The research focuses on a new design method which improves the cable printer with the Bluetooth communication technology. The key point of this technology is to use the two USB interfaces (send and receive endpoints) as the adjacent connection. Based on the Bluetooth HCI protocol, we use USB technology to resolve the printer data formats, and finally accomplishes the mutual change of USB data and Bluetooth HCI ACL data formats. Testing analysis is carried out to solve the problem of packet loss of Bluetooth communication data, optimizing the SCM controller process again. The testing result shows that the Bluetooth printer communication system data is complete and a variety of print formats are supported. The print quality is high. If the controller’s performance and the blue-tooth's Baud rate are improved, the printing speed can be improved greatly. This design is practical and cost-efficient.
