The invention discloses a relay protection centralized printing method and system, and the method comprises the steps: enabling a relay protection device to automatically trigger a relay protection action when an external condition of the relay protection device meets a protection logic; the printing instruction is sent through the relay protection device; receiving a printing instruction through a serial port to Ethernet device, converting the printing instruction into a network signal, and transmitting the network signal to a management computer through the Ethernet; printing data in the network signals are classified and stored through the management computer; and the classified and stored information is searched through the management computer, and the required information is selected and printed through the printer. The serial port data of the plurality of relay protection devices are converted into Ethernet data by utilizing a data acquisition mode of converting multiple serial ports into Ethernet, and
