A printing apparatus suitable for printing on a print medium of a large size which is reduced in overall size and facilitates adjustment of printing timings of line printing heads therein. The printing apparatus comprises a plurality of line printing heads of the type wherein printing elements are disposed on a line along an end edge thereof. The line printing heads are disposed in a pair of rows spaced in the feeding direction of a print medium in a housing such that the printing elements along the end edges thereof are disposed in an alternate relationship in a pair of rows perpendicular to the feeding direction of a print medium and each located nearest to the other row of the printing elements. A pair of parallel rotatable platen means are disposed for cooperation with the pair of rows of printing elements on the line printing heads and include a plurality of platen rollers disposed in an opposing relationship to the line printing heads and a plurality of fixed dummy platens disposed in an alternate relationship with the platen rollers.
