PROBLEM TO BE SOLVED: To continue printing processing by dynamically selecting an alternate server even when a failure takes place in a server. SOLUTION: A server 14 decides an alternate server to a server 24 based on an alternate server selection condition of a device information table 290. An alternate request is performed to the server 24 by transmitting management information (device information table 290 and performance information table 292) stored in the server 14, stored reference D2 (printing request) and printing data D1 to the server 24. The server 24 updates the management information of the server 24 based on the management information transmitted from the server 14. It also stores the reference D2 and the printing data D1 transmitted from the server 14 in a spool. Next, the server 24 notifies a workstation 12W1 that the transmission destination server of the data D1 and the reference D2 is changed by the server 24 and notifies a printer 16P1 that the acquisition destination server of the data D1 is changed by the server 24.
