Abstract
An object of this invention is to provide an ink jet printing apparatus that can detect a state causing a printing operation failure without adding a sensor and also enhance the ease of handling on the part of the user while keeping an apparatus cost from rising. For this purpose, in a serial type ink jet printing apparatus, a travel range in which the print head can be moved is detected and it is decided whether the detected travel range is a proper travel range. When, for example, the travel range is determined to be less than a preset range, it is decided that there is an obstacle in a path of the print head and a decision result is displayed. When the travel range is determined to be a certain range, it is decided that the ink tank is not properly mounted on the print head and the corresponding indication is made.
