A printing control apparatus that succeeds in providing enhanced usability by giving a paper placement opportunity to users so that an operational burden can be reduced is provided. A printer control section controls a printing section to effect print standby with respect to one of a plurality of image-data pages that has been subjected to print-standby specification first by a standby specification command. After a sensor of a manual feeding tray in the printing section detects placement of a new sheet, the printing section is so controlled as not to effect print standby with respect to the remainder of the pages even if standby is specified by a standby specification command.
