A printing system includes a control unit configured to control an image forming unit to form an image on a sheet based on print setting information included in received job setting information, control a post-processing unit to execute a post-process corresponding to a designated type, and control a creasing unit.

An aligning unit stores a paper bundle that is formed by inserting a medium that is different from printed body text paper sheets conveyed from a printer into the printed body text paper sheets. A manual paper feeding unit stores a medium that is manually fed. A conveyance control unit makes the medium be conveyed from the manual paper feeding unit to the aligning unit after the body text paper sheets that include a page specified by a print job are stored in the aligning unit and before the body text paper sheet conveyed from the printer immediately afterwards is stored in the aligning unit.

A printing system comprises: a printing unit configured to print an image on a sheet; and a control unit configured to control to perform creasing at a first pressure at a portion, corresponding to an edge of a spine cover, of the sheet on which the printing unit has printed the image, and perform creasing at a second pressure different from the first pressure at a portion of the sheet that corresponds to a hinge.

A printing control apparatus performs binding processing for binding a plurality of sheets without using a staple to enable a user to easily separate a sheet from a sheet bundle after the binding processing. The printing control apparatus causes a binding unit to perform a binding processing for binding a plurality of sheets without using a staple, and then controls the binding unit to perform a binding processing for binding the plurality of sheets and a sheet different from the plurality of sheets.

The invention relates to the production of books with wire or spiral bindings or other comparable bindings, wherein sub-layers (2) made of punched sheets are collected one over the other in a successive manner into a book (5) at a collecting station (3), and the book is subsequently bound. According to the invention, a sub-layer (2) is held in a clamped manner by at least one lateral clamping device (12) which moves together with the sub-layer while the sub-layer is transported into the collecting position, while the sub-layers (10) already collected at the collecting station (3) are held in a fixed manner by means of at least one needle (13) which is moved upwards through the punched holes (4) from below. The clamping of the pliers is released only when the needles (13) are also located in the punched holes (4) of the newly conveyed sub-layers (2) as a result of the needles being moved upwards.

Convenience when case binding operation is confirmed is to be improved. A method of controlling an image forming system configured to perform case binding includes receiving a number of sheets on which a test print pattern image is to be printed, receiving a print instruction to print the test print pattern image, and performing control to perform printing based on the print instruction, wherein, in a case where execution of predetermined postprocessing different from the case binding is set and the print instruction is received, the control is performed to print the pattern image on the received number of sheets, and in a case where execution of the case binding is set and the print instruction is received, the control is performed to print the pattern image on a number of sheets greater by a predetermined number of sheets than the received number of sheets.
