DUPLEX PRINTING
A duplex printing system and method of configuring the same are described. In examples, an image, such as a test pattern, on one side of a print substrate is printed to be out of phase with an image, such as a test pattern, on the other side of the print substrate. This is achieved by adjusting a configuration of a print buffer that is located between first and second print engines of the duplex printing system. In particular examples, a length of a web within the print buffer is controlled such that the images are out of phase.
Curl Resistant Web Handling System
A web handling system is disclosed. The web handling system includes first dancer rollers coupled to engage and move a web of a print medium in a forward and backward direction upon stopping a printing operation and allow forward motion during the printing operation.
