To easily resume printing of prints or continuous outputs of different kinds of manuscripts after the printing is interrupted, by assigning output symbols to all prints output from an image-forming apparatus in accordance with a set mode, and controlling an operation of the apparatus in compliance with a table storing an output order.

A full-color print system adapted to multi clients consists of an image control apparatus (ESS) 20 communicating with a plurality of clients 10 (11, 13, 15, etc.), and an image-forming apparatus (IOT) 30 outputting and printing images taken by the ESS 20. A table in which symbols (numerals) are assigned to all output prints is provided at a control device controlling an image transmission of the ESS 20 and an output of the IOT 30 of the image- forming system. Since the control device controls each print command by the symbol, resumption of printing can be controlled with a print command symbol at the occurrence of jamming.
