主权项 1. A printing apparatus comprising: a printhead including an element array in which a plurality of printing elements are arrayed; a scanning unit configured to reciprocally scan said printhead in a direction perpendicular to an array direction of the printing elements; a driving unit configured to divide the element array into a plurality of groups, each including consecutive printing elements, and time-divisionally drive the printing elements in each group; a conveyance unit configured to convey a printing medium in the array direction of the printing elements; and a setting unit configured to set a driving order in the time divisional driving, wherein said conveyance unit performs a first conveyance operation of conveying the printing medium by a conveyance amount, which is an integer multiple of a width of the group, and a second conveyance operation of conveying the printing medium by a conveyance amount, which is not an integer multiple of the width of the group, and wherein said setting unit sets the driving order in the time divisional driving for each scan based on the conveyance amount by said conveyance unit.
