Zusammenfassung:	PROBLEM TO BE SOLVED: To save power consumption in a network to which a plurality of host devices and image forming devices are connected.SOLUTION: In a network printing system 1, a plurality of printers Pr1 to Prm and client devices C1 to Cn are connected to a network NW, the printers Pr1 to Prm acquire function information of each of the printers Pr1 to Prm and information from the client devices C1 to Cn and determine priority as a master printer which controls a power saving mode, a specified number of printers Pr1 to Prm having high priority calculate an average use performance M which is required in the network NW as the master printer, and control a power waving mode of each of the printers Pr1 to Prm and reevaluate the master printers at a specified period based on the priority, the function information and the average use performance M.
