PROBLEM TO BE SOLVED: To prevent the print processing speed and the entire resolution of a page image from lowering by providing a function for lowering the print quality of an image, corresponding to a data format for handing image data of a plurality of resolutions while structuring in a host computer depending on the write command memory size of a printer, to a predetermined lower limit quality thereby inhibiting intermediate rendering, and to enhance convenience by a function for setting a lower limit quality depending on a print object. SOLUTION: A computer constituting a printer system predicts an information amount when print data to be generated becomes a write command on a printer (S702), selects sub-images of appropriate resolution sequentially from an image corresponding to a data format for storing data of a plurality of resolutions while structuring depending on a designated print object (S706, S709) and transmits the selected sub-images to a printer for printing.
