Abstract

PROBLEM TO BE SOLVED: To provide an image forming device outputting an image onto large size paper when only the paper having larger size than necessary paper size exists on a tray. SOLUTION: When a printer 100 receives printing data from a host device (S20), the paper size B of the paper A set in a paper feeding tray 110 is detected by a paper size detection sensor 107 (S21). If the paper size C designated in the printing data is the same as the paper size B (S22; Y), the printing data is printed on the paper A (S23). Meanwhile, if the paper size B is smaller than the paper size C (S24; Y), the printing data is divided to such size that it can be printed on the paper A (S25), and the printing data divided to the paper A and adhesive information such as a line to cut off and a tab for sticking to perform processing to the paper size C are printed (S26).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a printer for printing on paper of another size when there is no paper of a required size.

[0002]

2. Description of the Related Art When outputting image data by an image forming apparatus such as a copying machine or a facsimile machine, if a sheet having a size corresponding to the size of the image data is not prepared, various techniques have been proposed to cope with the problem. ing. For example, Japanese Patent Application Laid-Open No. H11-309912 discloses a roll paper printer provided with a pre-cut process for removing the leading end of the paper.

[0003]

By the way, when image data is output by an image forming apparatus, there are cases where sheets set on a tray have only a sheet of a size larger than the image data, and a case where the sheet is smaller than the image data. Paper only. In such a case, there is a case where it is desired to output image data immediately without setting a sheet of a predetermined size on a tray. Therefore, a first object of the present invention is to
An object of the present invention is to provide an image forming apparatus capable of outputting to a sheet of a larger size when only a sheet of a size larger than a required sheet size exists in the tray. Further, a second object of the present invention is to provide an image forming apparatus capable of outputting to a sheet having a smaller size than a required sheet size when only a sheet having a smaller size exists in the tray. is there. A third object of the present invention is to provide an image forming apparatus capable of forming an image without deteriorating the quality of an image forming surface when forming an image on a sheet having a size different from a required sheet size. is there.

[0004]

According to the first aspect of the present invention, in an image forming apparatus provided with a tray on which sheets on which images are to be formed are set, a sheet size of the sheets set on the tray is detected. Paper size detection means,
A comparison unit that compares the paper size instructed to form an image with the paper size in the tray detected by the paper size detection unit, and as a result of the comparison by the comparison unit, When there is no sheet in the tray and there is a sheet having a size larger than the sheet size, a cutout line for forming the image of the image data on a sheet having a size larger than the sheet size and processing the image data to a predetermined sheet size. By printing the first
Achieve the objectives.

According to a second aspect of the present invention, in an image forming apparatus provided with a tray on which sheets on which images are to be formed are set, a sheet size detecting means for detecting a sheet size of the sheets set on the tray; A comparison unit that compares the paper size instructed to form an image with the paper size in the tray detected by the paper size detection unit, and as a result of the comparison by the comparison unit, If there is no sheet in the tray and there is a sheet of a size smaller than the sheet size, the image data is divided into regions, images are formed on a plurality of sheets of a size smaller than the sheet size, and the size of the sheet size is increased. The second object is achieved by printing the adhesive information on a cut line and a margin for processing into a piece.

According to a third aspect of the present invention, in the image forming apparatus according to the first or second aspect, when printing the adhesive information on a cut line or a margin for processing into a predetermined sheet size, the back side of the sheet is printed. The above-mentioned third object is achieved by printing the information on the third object.
