Printing apparatus, printing apparatus control method, and storage medium allowing editing to an image formed in a region to be cut off during postprocessing

摘要

A control method for controlling a printing apparatus configured to print image data and capable of conveying a printed sheet to a postprocessing apparatus configured to trim the printed sheet identifies and manages a region to be cut off by trimming and another region not to be cut off by the trimming and allows a user to easily edit an image included in the region to be cut off by the trimming. The control method includes displaying the image data, editing the displayed image data, obtaining information about a trimming position at which the postprocessing apparatus trims the sheet, and executing control for permitting editing of a first region, which is a region to be cut off by the postprocessing apparatus according to the obtained information and for restricting editing of a second region not to be cut off by trimming by the postprocessing apparatus.
