Abstract:
An element substrate comprises: a data latch unit for latching, based on a first signal, first print data and second print data which have been received by a reception unit; a first driving unit for driving printing elements based on a timing of a second signal and a logical operation result of printing element selection data and the first print data latched by the data latch unit; a delay unit for delaying the second signal by a predetermined time; an operation result latch unit for latching, based on the delayed second signal, a result of a logical operation of the printing element selection data and the second print data latched by the data latch unit; and a second driving unit for driving the printing elements in accordance with the latched operation result and the delayed second signal.
