Claim:
An information-processing apparatus for displaying a preview image based on document data generated by an application, comprising: a setting unit constructed to set double-sided printing; a designation unit constructed to designate a display of the preview image; a data-generating unit constructed to generate an obverse face preview image based on a page to be placed on the obverse face of a sheet included in the document data and a perspective-reverse-face preview image based on a page to be placed on the reverse face of the sheet included in the document data when the double-sided printing is set by setting unit and said designation unit designates the display of the preview image; and a display controlling unit constructed to display a merged preview image based on the obverse face preview image and the perspective-reverse-face preview image; wherein said display controlling unit displays the merged preview image so that the perspective-reverse-face preview image is recognizable as the image of the reverse face of the sheet.
