SYSTEM AND METHOD FOR OUTPUTTING COMPLEX IMAGE BY RECEIVING KEY DATA

PURPOSE: A system and a method for outputting a complex image are provided to shorten a waiting time of a user, and improve efficiency of a job performance by making several users perform several jobs at the same time, as a plurality of image input devices is linked to one image output device. CONSTITUTION: The image input devices(10) request the job progress to the image output device(20) by receiving key data of the user and transmit image data by receiving permission for the job progress in a job advance ranking of the user. The image output device determines the job progress of the image input devices by each job, permits the job progress of the corresponding image input device depending on the determined ranking, and performs the job by receiving the image data. The image input device includes a key input part, a data storage temporarily storing the image data, and controller requesting the job progress to the image output device when the key data is inputted and transmitting the image data when the request for the job progress is permitted.
