Image forming apparatus

A method of printing a plurality of images on one sheet of printing paper using an image forming apparatus, the plurality of images being selected to be printed on the printing paper, the method comprising:

• determining whether or not image data of each of the plurality of images is improper for being subjected to a scaling process and printed on the printing paper;
• subjecting proper image data of one or more of the plurality of images to the scaling process;
• using the scaled proper image data to prepare printing image data for printing the one or more images on the printing paper in such a manner that a region in which an image corresponding to the improper image data is to be printed is left blank and an image whose image data is proper is arranged at its corresponding region;
• and
• printing the one or more images on the printing paper according to the printing image data,
• wherein the process of printing on the printing paper is not performed if the total number of images whose image data is improper is equal to the maximum number of the images that can be printed on the printing paper.

A method of printing a plurality of images, comprising:

• a first step of assigning to each of the data sets of the plurality of images a number for specifying the respective image data set;
• a second step of determining whether given image data is proper image data or improper image data;
• a third step that, if the given image data is determined to be proper in the second step, appends the given image data to printing image data such that an image corresponding to that given image data is arranged, in an image corresponding to the printing image data, in a region that corresponds to a value of a stored first variable;
• a fourth step of incrementing a value of a stored second variable if the given image data is determined to be improper in the second step;
• a fifth step that, if the number assigned to the given image data is a final number, prints the images corresponding to the printing image data on one sheet of printing paper if the value of the second variable is determined to be different from a remainder that is obtained by dividing a total number of the plurality of images by a maximum number of image data sets that can be appended to the printing image data, and that does not print the images corresponding to the printing image data if the value of the second variable is determined to be equal to the remainder;
• a sixth step that, if the number assigned to the image data is not the final number, determines whether or not the given image data is the image data that is appended last to the printing image data;
• a seventh step that, if it is determined in the sixth step that the given image data is the image data that is appended last to the printing image data, prints the images corresponding to the printing image data on one sheet of printing paper if the value of the second variable differs from the maximum number, and that does not print the images corresponding to the printing image data if the value of the second variable is equal to the maximum number;
• an eighth step that, if it is determined in the sixth step that the given image data is the image data that is appended last to the printing image data, or after the fifth or seventh step, determines whether or not the region that corresponds to the value of the first variable is the region in which the image corresponding to the image data that is appended last to the printing image data is arranged;
• a ninth step that, if it is determined in the eighth step that the region that corresponds to the value of the first variable is not the region in which the image according to the image data that is appended last to the printing image data is arranged, increments the value of the first variable;
• and
• a tenth step that, if it is determined in the eighth step that the region that corresponds to the value of the first variable is the region in which the image according to the image data that is appended last to the printing image data is arranged, initializes the values of the first and the second variables;
• wherein the steps from the second step onward are performed on the image data of the plurality of images, in an order of numbers assigned in the first step.
