Description

  The present invention relates to an image forming apparatus and a program for forming an image on a double-sided printed recording medium.

  In an image forming apparatus such as a copying machine, a printer, or a facsimile machine, when an image is formed using a printed recording medium such as a letterhead, a miscopy may occur due to a mismatch between the orientation of the image and the printed recording medium. .

Therefore, for example, in Patent Document 1, the state of setting a letterhead or the like on a paper feed tray (the vertical direction of the paper, the orientation of the back and front of the paper) can be set from the operation display unit, and an image is formed. Describes a technique for determining whether or not the set vertical direction of the paper matches the image forming direction of the image and, if not, rotating the image to perform printing. . Further, it is determined whether or not the setting of the orientation of the paper back and front is set to be opposite to the printing surface on which a predetermined image is to be printed. There is also described a technique in which printing is performed by changing the printing order of images on the front and back sides of the paper when the image is in the opposite direction to the printing surface to be printed.

As shown in FIGS. 18B and 18D, the top-and-bottom direction of the top and bottom binding recording medium is reversed so that it can be easily viewed.

  When the user wants to output the recording medium after image formation by binding left and right or top, the user outputs and sets the binding direction (left and right binding or top binding) from the operation display unit. In the image forming apparatus, if the output setting is left and right binding, image formation is performed so that the top and bottom directions of the image on the back surface of the recording medium match. If the output setting is top binding, the image on the back surface of the recording medium is formed. The image is formed so that the top and bottom direction is reversed.

FIG. 19 shows the relationship between the binding direction output setting and the binding direction of a double-sided printed recording medium when an image is formed using a portrait double-sided printed recording medium.
