The present invention concerns a print job control system in which image-forming apparatus and computers are coupled each other through a network. The print job control system includes an image-forming apparatus, which includes an image reading section to generate first image data by optically scanning a document and conducting an optoelectronic converting operation, a first memory to store the first image data, header data corresponding to a property of the first image data, and job data corresponding to a property of an image-forming job including the first image data generated from a plurality of pages of the document, an image-forming section to form images based on the first image data stored the first memory, and a first network interface to bilaterally transmit the first image data between the first memory and a network of the network system; and a computer, which includes a second network interface, a second memory, and a control section to control an operation for storing data, received through the second network interface, in the second memory; wherein the control section creates a directory corresponding to the first image data, the header data and the job data in the second memory, and stores a job management file created based on the header data and the job data, each of which corresponds to the image-forming job, and second image data generated by converting the first image data, corresponding to the image-forming job, in the directory.
