Abstract:
An image forming system includes an information terminal and an image forming apparatus. The image forming apparatus stores a hash value of a file on which image forming operation is to be performed or has been performed. Upon a request to print a predetermined file at the information terminal, the information terminal generates a hash value of the predetermined file. The information terminal transmits print data and the hash value to the image forming apparatus only in the case where the information terminal determines that hash values stored by the image forming apparatus do not include the generated hash value.
