Abstract: An electronic device in the present disclosure includes the following: an imaging device configured to scan a paper sheet, wherein the paper sheet comprises a first side and a second side, wherein scanning the paper sheet produces an image; a display device; a printing image acquisition unit configured to acquire a printing image; an image forming apparatus configured to print the printing image; and a display control unit configured to control the display device to display, if the produced image includes an image of a paper sheet, a composite image that combines the acquired printing image and the image of the paper sheet within the produced image.

Abstract: An image forming apparatus includes: a job receiving unit that receives a job for executing printing; an image-quality-adjustment execution unit that executes a normal image-quality adjustment at an image-quality adjustment time and a prior image-quality adjustment before the image-quality adjustment time; an image-quality-setting receiving unit that receives an image-quality setting; a reply request unit that, within a specific state before the image-quality adjustment time since the job is received by the job receiving unit, requests a reply indicating whether to execute a prior image-quality adjustment if a specific condition for the reception of the image-quality setting is satisfied; and a printing execution unit that, if the reply indicates that the prior image-quality adjustment is to be executed, prints an image on a recording medium by executing the job after the image-quality-adjustment execution unit executes the prior image-quality adjustment.

Abstract: In regard to a print result of both-side printing, to display a preview image which allows intuitive understanding of both of the page order and the front-back relationship of each of the page images. When conducting both-side printing, a page of one page image to be formed on the front surface of a paper is identified, and a print preview image is displayed on display unit, in which a turned-over image g1 indicating a part of the uppermost paper of the stacked papers is turned over. And, on a first area p1 corresponding to the front surface section of the uppermost paper, a page image g12 to be formed on the section is displayed, while on a second area p2 corresponding to the back surface section of the same paper and on a third area p3 corresponding to the front surface section of the second paper, partial images g23 and g33 extracted from each of corresponding page images are displayed.
