Printing system and data transmission method thereof

摘要

A printing system and a data transmission method thereof are provided. The printing system includes a peripheral unit and a controller. The peripheral unit is configured to execute a data printing function and includes a digital data. The controller is coupled to the peripheral unit. The controller converts a digital control command to obtain an analog control signal, and transmits the analog control signal to the peripheral unit. The peripheral unit converts the analog control signal into the digital control command when the analog control signal is received by the peripheral unit. The peripheral unit converts a corresponding digital data into an analog signal according to the digital control command to transmit the analog signal to the controller.
