When performing image processing on a designated image by the function of the application, image data of the designated image is obtained in a second layer constituted by an instruction set executable by a processor. In a first layer constituted by a script instruction set, the print script of print content including the image data which has been obtained and converted into a data format interpretable by the first layer in the second layer is generated. The print script is rendered into print image data corresponding to a print resolution by interpreting the generated print script.
