A control device for a printing execution unit, wherein, in a case where a character region and a non-character region are included in an overlap region which includes an upstream end of a partial region configured to be printed by a first partial printing, the printing execution unit is caused to print a print image by: forming a plurality of character dots, which are dots in the character region included in the overlap region, by one of the first partial printing and a second partial printing, and not forming the plurality of character dots by another of the first partial printing and the second partial printing; and forming some of a plurality of non-character dots, which are dots in the non-character region included in the overlap region, by the first partial printing, and forming other dots of the plurality of non-character dots by the second partial printing.
