PROBLEM TO BE SOLVED: To calculate a variable print charge according to the number of printed sheets, the price of printed charged information, and an advertisement charge to be deduced by determining the value according to 1st value information of output information and 2nd value information of additional information added to the output information. SOLUTION: On a screen of 'print of advertisement', it is decided which button is pressed (S701). When a 'cancel' button is pressed, the process is ended without setting advertisement. When an 'OK' button is pressed, the output format of advertisement is transmitted to a CanDINet control part (S703) and a print charge determined by taking the output format of the advertisement into account is received. The CanDINet control part calculates a print charge on the basis of the charge of an information provider when no advertisement is printed. When advertisement is printed, the discount charge based upon the advertisement printing is subtracted from the calculated print charge to recalculate a print charge.
