  • Patent number: 10005293
    Abstract: A printing apparatus includes a feeding roller to feed a sheet, a conveyance roller conveys the sheet, a printing head prints on the sheet, a reversing path that reverses the sheet from a first surface to a second surface, and a control unit that controls feeding of a preceding sheet and a succeeding sheet fed next to the preceding sheet. The control unit starts feeding of the succeeding sheet when a trailing edge of the preceding sheet, which was reversed by the reversing path, reaches a predetermined position and feeds the succeeding sheet so that a distance between the trailing edge of the preceding sheet and a leading edge of the succeeding sheet is within a predetermined range.
