    摘要: A printing apparatus for printing on double-sides of a recording medium has a first print control unit for controlling an one-line exposure for the right or reverse side by a horizontal synchronous signal, and a second print control unit for controlling the one-line exposure for the reverse or right side by using this horizontal synchronous signal. A print start timing for the right side can be synchronized with a timing for the reverse side, and is capable of preventing a deviation in print position between the right side and the reverse side of the recording medium even by providing the print control units for the right side and the reverse side, individually.

    摘要: An image forming apparatus includes a reverse side print mechanism for printing on the reverse side of continuous paper, a surface print mechanism for printing on the surface of the continuous paper, and a width detecting mechanism for detecting a width of the continuous paper. The apparatus further includes a controller which, based on the detected paper width, determines a print start position on the reverse side of the continuous paper and controls the reverse side print mechanism to start printing from the determined print start position. Thus, even if the paper width is changed, the reverse side print start position can be set to a predetermined position.
