A recording apparatus has a buffer for dividing a storage area into a plurality of areas in a scanning direction of a recording head to record data by allowing a carriage loaded with the recording head to scan data on a record medium, and storing the divided image data in a divided area unit, and includes: a write control unit for controlling write address information about image data in the area unit for data of each color for storage of the image data divided in an area unit in the buffer; a read control unit for controlling for data of each color read address information for a read of image data stored in the buffer; and a record data generation unit for generating record data in a unit of the divided area based on the read image data according to the read address information.

Recording apparatus and method for controlling recording apparatus

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.
