A printing apparatus capable of conveying sheets to a sheet processing apparatus and to control the type of a sheet to be used as a cover sheet in a case where a book bound product is generated by switching back sheets each having an image printed, inverting the sheets and folding the inverted sheets, and to notify an error to a user based on the type of a sheet to be used as the cover sheet in a case where printing an image on the cover sheet is designated.

A multifunctional printer having a printer section, an auto document feeder, a scanner section, a print path, and a path guide. When the multifunctional printer is not in a print and scan mode, the path guide can move to a position that routes printed paper from the print path to a print output tray. When the multifunctional printer is not in a print and scan mode, the path guide can move to a position that routes printed paper from the print path to the auto document feeder, where it can be scanned.

An example scanner includes a tray, a document feeding member, a document feed error detection sensor, a reading member, and a processor. The processor, in a case where a document feed error is detected by the document feed error detection sensor, is to move the tray between a first position to feed a document, and a second position deviated from the first position, and control the document feeding member to perform a reverse feeding operation of feeding an erroneous document toward the tray. Based on performing the reverse feeding operation, the processor is to move the tray between the second position and the first position and control the document feeding member to perform a re-feeding operation of feeding the erroneous document to the reading member.

In an image forming system, a hardware processor controls whether the first sheet is conveyed to an upstream side of the image former via a first conveying path which reverses sides of the first sheet or via a second conveying path which does not reverse the sides of the first sheet as well as the first conveying path, when images are formed on both sides of a plurality of the first sheets by the image former, in order to narrow a space between a plurality of the first sheets.

A printing apparatus that is capable of executing, based on printing data, printing onto a first side of a printing medium and printing onto a second side, which is the back side of the first side, after the printing onto the first side is provided. A print density of a predetermined region at a rear end of the printing medium in a transporting direction at a time of printing of the first side is identified based on the printing data. Conversion data, which is a conversion coefficient to make the identified print density equal to or lower than a predetermined density, is acquired. The printing data is converted by means of the conversion data. Printing onto the first side is executed based on the converted printing data.

A printing apparatus capable of conveying sheets to a sheet processing apparatus and to control the type of a sheet to be used as a cover sheet in a case where a book bound product is generated by switching back sheets each having an image printed, inverting the sheets and folding the inverted sheets, and to notify an error to a user based on the type of a sheet to be used as the cover sheet in a case where printing an image on the cover sheet is designated.

When a job for executing both of a one-sided printing and a two-sided printing, the lowering of the productivity is suppressed and an output result a user desires is output.

An image forming apparatus capable of making a match between the orientation of a reference side of a sheet along which punched holes are formed and the orientation of an output image on the sheet in double-sided printing. It is determined whether or not to rotate an image based on whether the image is printed in a single-sided printing mode or a double-sided printing mode. In the double-sided printing mode, a reverse-side image is printed on a first surface of the sheet, the sheet is conveyed into the printing section through a double-sided conveying path, a front-side image is printed on a second surface of the sheet, and the sheet is discharged. In the single-sided printing mode, an image for single-sided printing is printed on a first surface of the sheet, and the sheet is discharged.
