Image forming apparatus, image forming method for printing images in an order different from an order of reading images

An image forming method comprising:

• starting reading of a plurality of images of document into a plurality of pieces of image data each representing the image;
• starting storing of the plurality of pieces of image data in a memory in an order of image reading;
• in response to reading of a first image of the plurality of images of document into first image data representing the first image, calculating a remaining number of readable images using the first image data;
• displaying the remaining number of readable images on a display panel;
• determining whether to continue reading of the plurality of images of document;
• in response to reading of each subsequent image of the plurality of images of document into subsequent image data representing the subsequent image, calculate an updated remaining number of readable images using the first image data and all subsequent image data;
• and
• display the updated remaining number of readable images on a display panel;
• and
• printing, on one or more recording media sheets, the plurality of images according to the plurality of pieces of image data having been stored in the memory, in an order different from the order of image reading, based on a result of the determining.

A non-transitory recording medium storing a plurality of program codes which, when executed by one or more processors, causes the processors to perform a method, the method comprising:

• starting reading of a plurality of images of document into a plurality of pieces of image data each representing the image;
• starting storing of the plurality of pieces of image data in a memory in an order of image reading;
• in response to reading of a first image of the plurality of images of document into first image data representing the first image, calculating a remaining number of readable images using the first image data;
• displaying the remaining number of readable images on a display panel;
• determining whether to continue reading of the plurality of images of document;
• in response to reading of each subsequent image of the plurality of images of document into subsequent image data representing the subsequent image, calculate an updated remaining number of readable images using the first image data and all subsequent image data;
• and
• display the updated remaining number of readable images on a display panel;
• and
• printing, on one or more recording media sheets, the plurality of images according to the plurality of pieces of image data having been stored in the memory, in an order different from the order of image reading, based on a result of the determining.
