When the time period is night, processing advances to step Sto set the initialization speed of a line feed motor to the first speed (v1), and to step Sto 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 Sto detect a cover open/closed state. When the cover is open, the processing advances to step Sto set the initialization speed of the line feed motor to the first speed (v1). When the cover is closed, the processing advances to step Sto 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 Sto execute initialization operation of the line feed motor at the second speed (v2).

Printing apparatus and control method therefor

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.

Data processing apparatus, data processing method, program, and ink jet printing system

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.
