ABSTRACT:
A computer generates a print ID based on input image data on which a forgery preventing process is performed, and transfers the print ID to a printer. The printer generates a common key corresponding to the print ID, and transfers it to the computer. The computer encrypts the image data using a common key, represents it as a print control command, and transfers the data with the print ID to the printer. The printer analyzes the command of the print control data, extracts the encrypted print image data, decrypts the data using the common key, and stores the decrypted print image data in a storage medium, thereby preventing the data from being printed on a number of unspecified printers.
