Abstract: When the time period is night, processing advances to step S13 to set the initialization speed of a line feed motor to the first speed (v1), and to step S15 to execute initialization operation of the line feed motor at the first speed (v1). When the time period is morning or daytime, the processing advances to step S12 to detect a cover open/closed state. When the cover is open, the processing advances to step S13 to set the initialization speed of the line feed motor to the first speed (v1). When the cover is closed, the processing advances to step S14 to set the initialization speed of the line feed motor to the second speed (v2) which is higher than the first speed (v1). The processing advances to step S15 to execute initialization operation of the line feed motor at the second speed (v2).

Abstract: An ink jet printing system is provided which has an ink jet printing apparatus and a host and which alleviates a data processing load on the ink jet printing apparatus, prevents a reduction in a printing operation speed, and realizes a cost reduction. The ink jet printing apparatus of this invention has an ink receiving member for receiving waste ink ejected onto an overrunning area outside edges of a print medium and an accumulated value memory section for storing an accumulated value equivalent to waste ink volumes ejected onto the ink receiving member. The host includes a waste ink volume setting section for obtaining a value equivalent to a waste ink volume and a data sending section for sending data to the ink jet printing apparatus. The accumulated value memory section of the ink jet printing apparatus stores the accumulated value equivalent to waste ink volumes obtained by the host.

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.

Abstract: A printing apparatus of the invention acquires a velocity and an acceleration of a printing medium when a rear end of the printing medium passes through a detection lever. A correction amount for the rear end of the printing medium is determined in accordance with the velocity and the acceleration of the printing medium. The correction amount is a transportation amount of the printing medium during a physical return time after the rear end of the printing medium passes through the detection lever until the detection lever is detected by a sensor. A remaining region from a printing position of a print head up to the rear end of the printing medium is controlled in accordance with the correction amount for the rear end of printing medium.
