For this purpose, in a serial type ink jet printing apparatus, a travel range in which the print head 303 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, 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, it is decided that the ink tank is not properly mounted on the print head and the corresponding indication is made.
