1. A method of controlling an information processing apparatus configured to control display of a user interface screen of a print control program used for print setting of print data to be transmitted to a printing apparatus, the method comprising: adjusting a predetermined image, after determining an output region corresponding to an output paper size set by the print setting in a display area of the user interface screen, such that a size of the predetermined image is adjusted to a size of the output region; and displaying the image having the size adjusted in the output region of the display area, wherein adjusting the predetermined image includes, if a length of each side of the output region is shorter than or equal to a corresponding side of the predetermined image and not longer than a corresponding side of a distribution region of a main object in the predetermined image set in advance, performing reduction processing of the predetermined image and cropping the reduced image such that a removed portion of the distribution region of the main object is at a minimum, and wherein, according to the reduction processing, in a case where the predetermined image is reduced such that the distribution region of the main object is inscribed in the output region, if a length of each side of the reduced image is longer than or equal to a corresponding side of the output region, the predetermined image is reduced such that the distribution region of the main object is inscribed in the output region, and in a case where the predetermined image is reduced such that the distribution region of the main object is inscribed in the output region, if a length of at least one side of the reduced image is shorter than a corresponding side of the output region, the predetermined image is reduced such that the predetermined image circumscribes the output region.
