Printing apparatus, method and storage medium for conveying sheets intermittently to printhead while conveyed sheets partially overlap

A method of controlling a printing apparatus including a first roller configured to feed a sheet, a second roller configured to convey the sheet fed by the first roller, a third roller configured to convey the sheet conveyed by the second roller, and a printhead configured to print an image by discharging ink on the sheet, wherein the third roller performs intermittent driving which is repeating conveyance of the sheet and stopping conveyance of the sheet, and the printhead prints on the sheet in a state in which the third roller stops the conveyance of the sheet, the method comprising:

• controlling the first roller to feed a succeeding sheet so as to have an interval between a trailing edge of a preceding sheet fed before the succeeding sheet and a leading edge of the succeeding sheet;
• controlling the second roller to perform intermittent driving in a state where the third roller performs the intermittent driving for printing on the preceding sheet and the preceding sheet is conveyed by the second roller;
• and
• controlling the second roller to convey the succeeding sheet in a state where the third roller stops the conveyance of the preceding sheet in the intermittent driving after the trailing edge of the preceding sheet passes the second roller.

A printing apparatus comprising:

• a first roller configured to convey a sheet;
• a second roller configured to convey the sheet conveyed by the first roller;
• a printing unit configured to print on the sheet conveyed by the second roller;
• and
• a conveyance control unit configured to control conveying the sheet,
• wherein the conveyance control unit controls conveying a succeeding sheet so as to have an interval between a trailing edge of a preceding sheet conveyed before the succeeding sheet and a leading edge of the succeeding sheet, and
• wherein the conveyance control unit controls to drive the first roller in synchronization with driving of the second roller in a state where the printing unit prints on the preceding sheet and the preceding sheet is conveyed by the first roller, and to drive the first roller not in synchronization with driving of the second roller so as to make the succeeding sheet catch up with the preceding sheet in a state where the printing unit prints on the preceding sheet after the trailing edge of the preceding sheet passes the first roller.
