1. A control device of a printing execution mechanism,the printing execution mechanism comprising:

  • a printing head having a plurality of nozzles configured to discharge liquid droplets; and

    a conveyance mechanism configured to convey a sheet in a conveying direction, the conveyance mechanism comprising;

    an upstream holding member provided at a more upstream side than the printing head in the conveying direction, the upstream holding member being configured to hold the sheet; and

    a downstream holding member provided at a more downstream side than the printing head in the conveying direction, the downstream holding member being configured to hold the sheet,the printing execution mechanism being configured to perform a printing by alternately executing a partial printing by the printing head and conveyance of the sheet by the conveyance mechanism for a plurality of times,the control device being configured to;

    execute first control processing of controlling the printing execution mechanism to perform the printing on a first surface of the sheet, the first control processing comprising;

    conveying the sheet to a first position in the conveying direction by the conveyance mechanism, the first position being a position at which;

    the sheet is to be held by the upstream holding member;

    the sheet is not to be held by the downstream holding member; and

    a downstream end of the sheet is located between the upstream holding member and the downstream holding member; and

    starting the printing on the first surface of the sheet by executing the partial printing on the first surface of the sheet located at the first position by the printing head after the sheet is conveyed to the first position in the first control processing; and

    execute second control processing of controlling the printing execution mechanism to perform the printing on a second surface of the sheet after the first control processing is executed, the second control processing comprising;

    conveying the sheet to a second position in the conveying direction by the conveyance mechanism, the second position being a position at which;

    the sheet is to be held by the upstream holding member;

    the sheet is not to be held by the downstream holding member; and

    the downstream end of the sheet is located at a more upstream side than the downstream end of the sheet located at the first position; and

    starting the printing on the second surface of the sheet by executing the partial printing on the second surface of the sheet located at the second position by the printing head after the sheet is conveyed to the second position in the second control processing.
