PROBLEM TO BE SOLVED: To provide a transmission packet filter which solves a problem that when a transmission packet filter rule is synchronized between a print control device and an image formation device, they are caused to be incapable of communicating with each other.SOLUTION: In a print control device (201) and an image formation device (207) communicating with each other: the print control device includes transmission filter rule transmission means (S805) for transmitting a transmission filter rule to the image formation device; and the image formation device includes transmission filter rule changing means (S806) for receiving the transmission filter rule transmitted by the transmission filter transmission means of the print control means so as to change the transmission filter rule, and transmission permission adding means (S810) for adding transmission permission to the print control device to the transmission filter rule changed by the transmission filter rule changing means. |
