  • Publication number: 20240184492
    Abstract: Disclosed are a document processing device and a signal transmission method thereof. The document processing device includes a processor and a printing engine. The processor is connected to the printing engine. The processor receives a document output command to generate a first differential signal. Then, the printing engine receives the first differential signal and converts the first differential signal into a first interference-free information packet. When the printing engine has already obtained the first interference-free information packet, the printing engine sends a buffer status checking signal to the processor. The document processing device uses the transmission of the first differential signal to reduce printing information errors caused by static interference, so as to achieve the purpose of improving the accuracy of printing information.
