1. A display processing apparatus comprising: circuitry configured to: scale dimensions of a background proportionally to dimensions of a display, display a first image of the background on the display according to the scaled dimensions of the background, scale dimensions of a recording medium to the scaled dimensions of the background, superimpose a second image of the recording medium on the first image of the background according to the scaled dimensions of the recording medium, the second image including a third image of an object that is to be printed on the recording medium, wherein the circuitry changes a magnification of the third image so that the third image has a scaled size of the object proportional to the scaled dimensions of the recording medium, and provide a user of the display processing apparatus with a preview of a size of the object, which is to be printed on the recording medium, against the background.
