A charging processing unit calculates a pre-charged amount of money based on print conditions and charges the calculated pre-charged amount of money to a card through a card reader. A job control unit starts a print job to print until a penultimate page, when pre-charging is finished. Further, when an accumulated amount of money is specified by generating image data of the final page and the accumulated amount of money is smaller than the pre-charged amount of money, the printing is stopped before the final page is printed. The charging processing unit causes an UI control unit to display a message requesting to place the card again. When the card is placed in response to the message and pieces of the card information matches each other, a refunding process is carried out. The job control unit restarts printing the final page after a refunding process.
