Claim:
A printer comprising: a receiving unit for receiving an image from an external communication terminal; a display unit for creating a print image of the image received by the receiving unit and displaying a preview of the print image; a printing unit for printing the image received by the receiving unit; a loss detecting unit for detecting a loss of a part of the image received by the receiving unit and displayed by the display unit as the preview of the print image, and supplying a warning notification to an operator upon detecting the loss of the part of the image; and a trimming unit for determining whether or not the operator has input a trimming region for the print image so that a lost part of the print image is designated to be removed by trimming after the loss has been detected by the loss detecting unit and the warning notification has been supplied, wherein when the trimming unit determines that a trimming region has been designated, the trimming unit supplies the designated trimming region to the display unit that uses the designated trim region to create a trimmed print image obtained as a result of the designated trimming region being trimmed and displays a preview of the trimmed print image with the warning notification being removed, and the printing unit prints the trimmed print image when instructed to do so by a print command input from the operator.
