Print control apparatus, print control method, and storage medium

Abstract

If a print medium size is set as a print setting for print target data, a print control apparatus causes a printing unit to print an image with a size corresponding to the print medium size based on the print target data. If the print medium size is not set as the print setting, the print control apparatus causes the printing unit to print an image with a size corresponding to a candidate print medium size obtained by a sensor detecting the size of the print medium.

What is claimed is: 
     
         1 . A printing apparatus comprising:
 a display unit; and   a printing unit configured to print an image based on print target data received from an external device,   wherein the display unit displays a screen for a user to designate a size of a print medium, if a sensor detects opening or closing of a cassette for containing the print medium;   and, if a print medium size is not set at the external device by a user as a print setting for the print target data, the printing unit prints an image having a size corresponding to a designated size which is designated by the user on the screen based on the print target data, and, if the print medium size is set at the external device by a user as the print setting and the print medium size does not correspond to the designated size, the printing unit does not print an image on the print medium based on the print target data,   and, if the print medium size is set at the external device by a user as the print setting and the print medium size corresponds to the designated size, the printing unit prints an image having a size corresponding to the print medium size on the print medium, based on the print target data.
