This invention provides an automatic printing trace system, comprising a paper feeding and scanning mechanism, a calculation and waiting mechanism, a printing mechanism, and a calculation module. The paper feeding and scanning mechanism and the printing mechanism are respectively connected to the two ends of the calculation and waiting mechanism. The calculation module is electrically connected to the paper feeding and scanning mechanism, the calculation and waiting mechanism, and the printing mechanism. The paper feeding and scanning mechanism scans documents and then feeds them to the calculation and waiting mechanism, while simultaneously transmitting the scanned image to the calculation module for processing. The calculation and waiting mechanism temporarily stores the scanned documents. After the calculation module finishes processing the document, it feeds it to the printing mechanism, which then prints the document based on the calculation result. This invention eliminates the need to adjust the image scanning speed of the paper feeding and scanning mechanism, allowing for direct feeding of quickly scanned documents to the calculation and waiting mechanism. The calculation and waiting mechanism then transmits the document to the printing mechanism for printing after the calculation module has finished processing, thereby improving the efficiency of the automatic printing trace system.
