The serial number of a first printer in which a network board is installed before power supply of the first printer is turned is stored in the network board. The network board determines whether or not the current serial number of the first printer in which the network board is currently installed and the serial number of a second printer in which the network board is installed before the power supply of the first printer is turned ON are identical. If the two serial numbers are determined to be not identical, the network board transmits the model name of the first printer to a management server. When the management server receives the model name of the first printer, the management server transmits the configuration file associates with the model name of the first printer to the network board.
