Abstract: A print substrate transport system comprises a print substrate supply mechanism and a tensioner. The print substrate supply mechanism is configured to advance print substrate to a printing zone in a discontinuous motion. The tensioner is provided downstream of the print printing zone and is configured to guide a path of the print substrate from the printing zone to a post-processing zone, to control tension in the print substrate in the post-processing zone, and to convert the discontinuous motion of the substrate to continuous motion. A print substrate transport method comprises supplying a print substrate to a printing zone in a discontinuous motion, controlling a tension of the print substrate on a path downstream of the printing zone and converting the motion of the substrate from the discontinuous motion to a continuous motion.

Abstract: Examples relate to a drying cylinder for an image forming apparatus. The drying cylinder comprises a curved wall and a plurality of gas outlets spaced apart over the curved wall. The drying cylinder is to continuously rotate about its longitudinal axis and provide gas through the plurality of gas outlets perpendicularly onto a print medium with printing fluid deposited thereon to dry the printing fluid.
