<P>PROBLEM TO BE SOLVED: To provide a printing system which eliminates uselessness of power consumption by efficiently managing a power supply of a printing apparatus even in a state that many host devices and printer apparatuses are connected on a network. <P>SOLUTION: In the printing system, a plurality of host devices and a plurality of printing apparatuses are connected via a network. When a main power supply of the printing apparatus is switched on and when the main power supply is not switched on, first decision of deciding whether powered host devices of a preliminarily set number or more are connected to the network, and second decision of deciding whether there are other printing apparatuses which are in operation and connected to the network are made. On the basis of the decision results, the main power supply of the own printing apparatus is switched on or driving of the main power supply of the own printing apparatus is stopped, and starting of printing apparatuses not in operation is indicated or an indication of stopping starting of printing apparatuses in operation is made. Printing processing is thus performed by eliminating uselessness of power consumption. <P>COPYRIGHT: (C)2012,JPO&INPIT |
