A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

In one example, a system can include a media pathway to transport a media into a stacking region, a clamp pathway to move a clamp along the clamp pathway, and a registration surface. The registration surface may be positioned between an edge of the media pathway and the clamp pathway.

A printing apparatus can be downsized while degradation in the print quality can be suppressed. To perform skew correction on a second print medium on which printing is to be performed subsequent to a first print medium, a first conveying unit disposed upstream of the printing position where the printing unit performs printing on the print medium is stopped. Then, driving and stopping of third conveying unit disposed downstream of a second conveying unit is controlled, depending on whether the first print medium after printing has already passed by the second conveying unit when the first conveying unit is stopped, the second conveying unit being driven by the same driving source as that for the first conveying unit and being disposed downstream of the printing position.

An intermediate unit includes a transportation path along which a medium, on which printing has been performed by a printing unit that performs printing on the medium by using liquid, is transported to a post processing unit that performs post processing on the medium. The transportation path is provided with a drying unit that accelerates the drying of the medium. The drying unit is driven according to the printing data.

A registration system for a printing device and a method for controlling the same are disclosed. For example, the registration system includes at least one sensor, omni wheels, a motor coupled to each omni wheel, a translating carriage, and a processor communicatively coupled to the at least one sensor, the motors, and the translating carriage, wherein the processor calculates a desired movement to move the omni wheels and the translating carriage based on the position of the print media.

An example disclosed media processing device includes an image processing unit; a first optical registration sensor; and a second optical registration sensor spaced apart from the first optical registration sensor along a first axis by a first distance associated with a gap between media units on a web.
