Abstract:
A printing apparatus conveys preceding and following sheets to form an overlapping portion where a trailing edge of the preceding sheet and a leading edge of the following sheet overlap each other at a printing position facing an ejection port surface of a printing unit, and prints the preceding and following sheets by ejecting ink from ejection ports based on a relative movement between the printing unit and the preceding and following sheets. The printing unit delays ink ejection timing for printing the overlapping portion of a sheet located closer to the ejection port surface at a position facing the ejection ports from ink ejection timing for printing a non-overlapping portion where the preceding sheet and the following sheet do not overlap each other in one of the preceding sheet and the following sheet.
