To exclude a negative means for printing images but to positively perform printing and to charge the printed result substitutively.

Inside a 'stamp card', there is a counter area COUNT showing a usable number and when printing is instructed, first of all, it is checked whether this COUNT is '0' or not (S601). When the COUNT is not '0', printing a stamp pattern PTN is performed (S602). After printing for one piece is performed, '1' is subtracted from the COUNT (S603). It is discriminated whether or not the COUNT becomes '0' as a result of the subtraction (S604). In the case of '0', since the stamp pattern in this stamp card can not be used any more, that pattern is erased (S605).
