<P>PROBLEM TO BE SOLVED: To output difference information between a last output drawing and a latest drawing to each destination of the drawing when the drawing sent to the plurality of destinations is revised a plurality of times and when the drawings sent at last to the respective destinations are not necessarily equal. <P>SOLUTION: An image output device receives image forming instruction information including output-instructed output instruction image information and attribute information including a drawing number of the output instruction image information and a destination of the output instruction image information, obtains already output image information wherein the drawing number and the destination of the attribute information included in the received image forming instruction information based on output history information wherein association relation among an identification code for identifying the last output already output image information of the already output image information output in the past, the destination of the last output already output image information, and the drawing number of the last output already output image information is represented in each destination, generates the difference information between the output instruction image information and the last output already output image information, and outputs the output instruction image information and the difference information. <P>COPYRIGHT: (C)2011,JPO&INPIT |
