Abstract
Abstract An image printing apparatus which enables an appropriate operation in accordance with a user's judgment even when printing operation is halted due to no ink residue. After the printing operation is halted due to running out of ink residue, the user judges whether or not a page, where printing operation is performed at the time of detection of no ink residue, is to be printed again, or to delete the image data corresponding to the printed page from an image memory. If any subsequent printing operation is necessary, an ink cartridge is exchanged and the printing operation is resumed. Ink residue detection is performed for the resumed printing operation, and image data is deleted or maintained according to the detected result.
