A printing control apparatus confirms whether a predetermined free space is present to stabilize an operation of a system. If it is determined that the predetermined free space is not present, the printing control apparatus deletes at least a part of stored print data. In a case where the predetermined free space becomes available by preliminarily performed deletion processing, the printing control apparatus stores print data of a first copy. Then, in the print processing for second and subsequent copies, if print data of a target page is already present, the printing control apparatus skips the processing for generating the print data of the target page.
