21 Claims

1. A printing apparatus comprising:

a print characteristics analyzing unit for determining print characteristics information of a printer based on a selected print setting for a print sheet type, the print characteristics information including a location on a print sheet of a degraded print quality area that occurs with the selected print setting for the print sheet type, wherein the print characteristics analyzing unit determines whether the location of the degraded print quality area occurs towards either a leading edge or a trailing edge of the print sheet, by referring to print characteristics information stored in association with the print sheet type;

an image orientation determination unit for determining an orientation of an image including a location of a top and a bottom of the image;

a print orientation determination unit for determining a print orientation of the image on the print sheet, based on the location of the degraded print quality area for the type of print sheet determined by the print characteristics analyzing unit, and the orientation of the image determined by the image orientation unit, by orienting the bottom of the image with the leading or trailing edge of the print sheet such that the bottom of the image is located at the degraded print quality area of the print sheet; and

a printing unit for printing the image based on the print orientation determined by the print orientation determination unit.
