When "store" of intermediate data is designated in a print process, a spooler stores intermediate data and an output job setup file in a spool file. When the stored job is selected, a previewer displays a list of jobs, and displays a print preview image. In this case, if "Same side on" is designated, pages of successive jobs are laid out without any gaps. If "new sheet" is designated, pages of the trailing job are laid out on a new sheet. If "Other side on" is designated, pages of the trailing job are laid out on a new surface.
