  • Patent number: 10894432
    Abstract: A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

  • Publication number: 20200380321
    Abstract: The invention provides a printing apparatus, a printing control method, and a processing apparatus, which suppress the occurrence of rework after a start of a printing operation and suppress an output of a printing result not intended by a user due to a mismatch between a state of expansion or contraction and print settings. To this end, printing is performed in print processing by determining whether or not an operable state is established which is a state of expanding a housing to a second position.

  • Publication number: 20190224996
    Abstract: A printing apparatus includes a feeding roller configured to feed sheets, including at least a preceding sheet and a succeeding sheet, a conveyance roller configured to convey the sheets fed by the feeding roller, and a printing unit configured to print on at least one sheet, of the sheets conveyed by the conveyance roller. A conveyance control unit controls the conveying of the sheets by the conveyance roller to form an overlap state, in which a leading edge of the succeeding sheet overlaps with the preceding sheet. In a case in which the conveyance roller conveys the succeeding sheet to a printing start position at which a printing operation is started by the printing unit, and the conveyance control unit forms the overlap state, the printing unit is configured to print on an overlapping area in which the preceding sheet and the succeeding sheet overlap.
