Patent ID: 8529144

Claim:
A printing system comprising: a plurality of print modules operating in a simplex mode in which an image is formed on a front surface of a continuous medium and in a duplex mode in which an image is also formed on a rear surface of the continuous medium; a first feed device that feeds the continuous medium; at least one of the plurality of print modules being a first print module that forms an image on the continuous medium fed from the first feeding device; a bidirectional guide comprising a first transport path along which the continuous medium is transported in from the first print module, and a second transport path along which the continuous medium is transported out in a direction that is a reverse of, and substantially parallel to, a direction of the first transport path, the first transport path and the second transport path including at least one pair of support rollers disposed adjacent to each other allowing the continuous medium to be threaded therebetween and fed in the direction of the first transport path or the second transport path, the at least one pair of support rollers individually turning in a same direction whether transporting the continuous medium along the first transport path or the second transport path; a first post-processing device that post-processes the continuous medium transported out by the second transport path of the bidirectional guide; at least one of the plurality of print modules being a second print module that forms an image on the continuous medium transported out by the first transport path of the bidirectional guide; and a second post-processing device that is provided on a downstream side of the second print module and that post-processes the continuous medium.
