A printing system includes: a first printing unit that performs printing on a medium on the basis of first printing data; a first inventing unit that is located downstream from the first printing unit in a transportation direction specific to the medium and performs an inverting operation that is an operation of inverting front and back sides of the medium; a second printing unit that is located downstream from the first inverting unit in the transportation direction and performs printing on the medium on the basis of second printing data; and a control unit that determines whether the first inverting unit needs to perform the inverting operation, on the basis of whether the second printing data indicates a printing page for the front or back side of the medium.

Printing system

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.

Bookbinding apparatus with sheet inserter

A conveyance control apparatus includes a stacking base that stacks ejected paper sheets, a sensor that detects a paper sheet after the paper sheet is ejected according to job data before the paper sheet is stacked on the stacking base, a detection time measuring unit that measures sensor-on time during which the sensor detects the paper sheet, a storage unit that stores near-full-stack time for judging whether stacked volume on the stacking base enters into a near-full-stack state, a judging unit that judges stack state on the stacking base based on paper sheet information of the job data and a measured result by the detection time measuring unit, and a conveyance control unit that performs control to temporarily stop paper sheet feeding and then to feed predetermined number of paper sheets, when the judging unit judges that the sensor-on time is equal to or greater than the near-full-stack time.

Conveyance control apparatus

When there is no post-processing performed in a post-processing device, a print job of original PDL data of a general-purpose data structure is output from a computer to a PDL control unit of an image forming device. While, when there is post-processing performed in the post-processing device, a print job of PDL data of an extended data structure generated by adding attribute data of the post-processing is output from the computer to an extended PDL control unit of the post-processing device. Then, the extended PDL control unit extracts the original PDL data of the general-purpose data structure and the attribute data of the post-processing, from the received print job. The attribute data of the post-processing is used for the post-processing control unit to control a post-processing unit. The original PDL data of the general-purpose data structure is output to the PDL control unit of the image forming device.

Post-processing apparatus for extracting received print data and forwarding the received print data to an image forming apparatus for processing

A printer which is connected to a post-processing apparatus, the post-processing apparatus performing a wrapped binding in which a paper sheet bundle including a plurality of inner paper sheets is wrapped by outer paper sheets, and which prints the outer paper sheets and inner paper sheets to be sent out to the post-processing apparatus, wherein the printer includes a control unit configured to control printing of the inner paper sheets and the outer paper sheets in cooperation with the post-processing apparatus, and the control unit is configured to set printing restart information of inner paper sheets and printing restart information of outer paper sheets, and controls a restarting of printing in accordance with the setting, when printing is restarted after an abnormal conveyance that occurred inside of the post-processing apparatus has been resolved.

Printer and storage medium

An image forming apparatus having a plurality of paper ejection devices includes a control unit which performs control to allow before a paper ejection device, which is continuously ejecting paper in the plurality of paper ejection devices, ejects paper over the maximum loading a paper ejection device which is not ejecting paper to prepare for starting an operation based on the time taken for the paper ejection device which is not ejecting paper to become operable and the number of ejectable sheets before a loading of the paper ejection device which is continuously ejecting paper reaches the maximum loading.

Image forming apparatus

A printing system includes: a printing unit; a post-processing unit for performing predetermined post-processing on printed printing paper sheets ejected from the printing unit; a priority setting section, in which a priority of removal of a cause of suspension among the units when operations of each unit are suspended due to a predetermined cause is set in advance; and an informing section for informing the user to remove the cause of suspension according to the priority set in the priority setting section.
