A method of making a print by the use of a photographic printer in which a variable masking frame is changed in size by a pulse motor and a photographic paper is transported by a pulse motor. When taking alpha c, alpha p, K1 and K2, and Pfo for a correction value common to all print sizes, a correction value for a specific print size, a constant, and a number of drive pulses obtained by dividing an acutally transported distance of the photographic paper by a distance df of transportation per one pulse, respectively, the corrected number of drive pulses Pf applied to the pulse motor for controlling the photographic paper is obtained by calculating the following expression: Pf=( alpha c/K1)x( alpha p/K2)xPfo When taking beta c, beta p, K3 or K4, and Pmo for a correction value common to all print sizes, a correction value for a specific print size, a constant, and a number of drive pulses obtained by dividing a moved distance of the masking frame by a distance dm of movement of the masking frame per one pulse, respectively, the corrected number of drive pulses Pm for controlling the masking frame is obtained by calculating the following expression: Pm=Pmo+( beta c-K3)+( beta p-K4)
