1. A printing apparatus comprising:
a feeding unit configured to feed a printing sheet; a conveyance unit configured to convey the printing sheet fed by the feeding unit; a print-head configured to print on the printing sheet conveyed by the conveyance unit by discharging ink; a conveyance control unit configured to control conveyance of printing sheets to form an overlap state in which a trailing edge of a preceding sheet as the printing sheet precedingly fed and a leading edge of a succeeding sheet as the printing sheet succeedingly fed following the preceding sheet overlap each other; and a preliminary discharge control unit configured to control the print-head to execute a preliminary discharge operation in which ink that does not contribute to printing is discharged between a completion of printing on the preceding sheet and a start of printing on the succeeding sheet, wherein the preliminary discharge control unit controls the print-head to execute the preliminary discharge operation in a case that the overlap state is not formed between the preceding sheet and the succeeding sheet, and not to execute the preliminary discharge operation in a case that the overlap state is formed between the preceding sheet and the succeeding sheet.
