Abstract: There are provided a receipt completion deciding unit 22 for deciding whether receipt of a print job is completed or not and a print job transferring unit 23 for transferring a print job of a non-received part to a print server other than a self server. In the case in which transmission of the print job to either of print servers 200-1 and 200-2 is delayed because of a difference in a transmission speed of the print job to the print servers, the print job in the non-received part is transferred to the other print server from the print server completing the receipt of the print job earlier. Consequently, the receipt of the print job in the other print server can be completed earlier as compared with the case in which the print job in the non-received part is continuously populated from a client terminal 100 to the other print server at a lower transmission speed.
