A printing system comprises a print station and print medium transport system. The print medium transport system comprises a track and a transport apparatus engaged with the track. The track defines a transport path past the print station, the transport path has a print medium entry point and a print medium exit point. The transport apparatus comprises: a drive for moving the transport apparatus along the track; and a gripping system. The gripping system can be moved between a first position in which a sheet of print medium is gripped and a second position in which the sheet of print medium is released. In use, the gripping system is configured to be in the first position when the transport apparatus is in motion along the track from the print medium entry point to the print medium exit point.

Provided is a lay-flat book block production apparatus. The apparatus comprises a glue dispenser, the glue dispenser to transition between an active state in which glue is to be provided to one side of the web which is to be guided past the glue dispenser and an inactive state in which glue is not to be provided to the web which is to be guided past the glue dispenser. The apparatus further comprises a folding unit, wherein the folding unit is to fold the web along a plurality of crease lines wherein each of a plurality of flat portions of a side of the folded web faces another of the plurality of flat portions of a same side.

A computer-implemented method of controlling the creation of a printed document includes the steps of: retrieving print information for generating a print job, said print information specifying characteristics of a document to be printed; retrieving at least one attribute of a print finishing device, said attribute defining a constraint imposed on the print job for printing said document, when the printed document is processed in said print finishing device; and generating a print job based on said print information and said constraint. In one example, retrieving said at least one attribute of a print finishing device includes establishing a communication link to said print finishing device and prompting the print finishing device to transmit the at least one attribute. Said communication link can be established and used on-line at the time of generating the print job or in advance.

Sheet length data is received for printed media sheets passed through a printing device. A length difference between the printed media sheets is calculated, and in response to the length difference exceeding a specified threshold, an alignment correction in a finishing device is initiated to align the printed media sheets.

Initiating alignment correction of printed media sheets

In an embodiment, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to receive sheet length data for two paper sheets of a same standard dimension passing consecutively through a printing device. The processor calculates a length difference between the two paper sheets, and when the length difference exceeds a two-sheet threshold, it initiates an alignment correction cycle in a paper finishing device.
