Claim:
A printing apparatus comprising: a printing unit group having a plurality of printing units executing printing on a print surface of a plurality of printing mediums, the plurality of printing units executing the printing in parallel; a turnover unit turning over front and rear surfaces of the plurality of printing mediums sent from the printing unit group; a path change unit changing a path, along which the plurality of printing mediums are transported from the printing unit group to the printing unit group again via the turnover unit, to any one of a plurality of paths corresponding to the printing units of the printing unit group; and a control unit controlling the path change unit, wherein the control unit controls the path change unit so that a difference is as small as possible between the length of a first path along which a first printing medium is transported from one printing unit of the printing unit group to another printing unit of the printing unit group via the turnover unit and the length of a second path along which a second printing medium is transported from a second printing unit of the printing unit group to another printing unit of the printing unit group via the turnover unit.
