Abstract：This paper briefly expounds the importance of the print function of the relay protection device, and lists the defects of the existing methods of printing function. According to the technical characteristics of the existing relay protection device generally using ESPON printer to achieve the printing function, the paper presents a method of the digitization of printing of the relay protection device. This method makes the normal operation of the print function of the relay protection device through the simulation of the printer, and stores in a file for the printing information received, and decodes printing information using the ESC/P encoding, and saves to the PDF file, so as to realize the digitization of printing. This method is simple and practical, safe and reliable, and it can improve the level of substation automation, and it is also in line with the development trend of the substation digitization and intelligence. It is of great practical value.
