A printer, comprising: a printing head for performing printing on one surface of a sheet; a platen roller that is arranged opposing the printing head and allows the sheet to pass between the printing head and the platen roller; a thermal activation head that is arranged substantially on a side opposite to the printing head with the platen roller therebetween, is opposed to the platen roller, is aligned in the same direction as the printing head on an outer circumferential surface of the platen roller, and performs thermal activation on a heat-sensitive adhesive surface that is the other surface of the sheet and develops an adhesive force upon heating; a stocking unit that is arranged downstream of the platen roller, temporarily stocks the sheet on which printing has been performed, and delivers the temporally stocked sheet toward a position between the thermal activation head and the platen roller; and regulating means arranged between the platen roller and the stocking unit, for preventing the sheet temporarily stocked in the stocking unit from being conveyed to a position between the printing head and the platen roller when the sheet is to be conveyed to the position between the thermal activation head and the platen roller.
