Printing apparatus, printhead, and driving method therefor
摘要:
An object of this invention is to drive different types of printing elements arranged in a printhead by proper powers without increasing the number of signal lines between the printhead and a printing apparatus main body, complicating the circuit configuration, and decreasing the printing speed. For this purpose, time division signals representing two driving periods corresponding to two types of printing elements are supplied to a printhead having the two types of printing elements which require different application powers in order to obtain a desired printing characteristic. Power is applied to the first type printing elements in the first driving period, and power is applied to the second type printing elements in the second driving period.
