The invention provides a paper path structure that is able to perform the following four functions: pass a sheet of paper through the paper path structure with is original orientation maintained; pass a sheet of paper through the paper path structure with its original orientation reversed; stack a sheet of paper in a stack repository with its original orientation maintained; and stack a sheet of paper in the stack repository with its original orientation reversed. The invention also provides a method to operate said paper path structure as well as a stacker and a printer comprising said paper path structure.

A transport mechanism is provided for transporting sheets of a print medium in a printing system. The transport mechanism include a first conveyor device having a first conveyor body which is configured to support a plurality of sheets of print medium, the first conveyor body being movable to convey the sheets along the transport path in the printing system; and a transfer system including a second conveyor device having a movable second conveyor body for supporting the sheets of print medium and conveying the sheets further along the transport path, the transfer system being configured to transfer the sheets of print medium from the first conveyor body to the second conveyor body in a transfer region. The second conveyor body is arranged adjacent or proximate to the first conveyor body in the transfer region, and the transfer system includes spacer means which is configured to maintain a predefined spacing between the first conveyor body and the second conveyor body in the transfer region. An associated method of transporting sheets of a print medium in a printing system is also disclosed.

A method of printing a receiving material wherein said receiving material is fed through a printer including a first and a second image-forming unit for substantially simultaneous printing of the front and back of said material in a transfer nip, whereby the two images are brought into register in the lateral direction with the receiving material by determining, prior to the formation of the images, a reference position at the transfer nip; forming the first image in such manner that part of said image which corresponds to the said reference position in the transfer nip substantially coincides therewith; and also forming the second image in such a manner that part of said image which corresponds to the said reference position in the transfer nip substantially coincides therewith; and feeding the receiving material to the transfer nip in such manner that that part of said material which corresponds to the reference position coincides substantially therewith at the transfer nip.
