In a method of controlling a printing apparatus which performs printing by adding image data already stored in the printing apparatus to payment transaction print data generated on the basis of input information concerning merchandise sales, a predetermined character string indicating a print position of the image data is retrieved from the payment transaction print data and the predetermined character string is extracted. A line number specified by the extracted predetermined character string is obtained and an image addition setting command is generated on the basis of the line number.
