PROBLEM TO BE SOLVED: To reduce the number of signal lines for controlling printing without increasing costs by a simple configuration. SOLUTION: A reference voltage signal terminal Vref of a temperature detecting part 304 and a common driving signal terminal Vcom of a driving controller 307 are connected with each other, so that the signal line Vcom and the signal line Vref are used in common. A signal terminal Csal1 for selecting an ink color of an ink detecting part 305 and a gradation control signal terminal M1 of the driving controller 307 are connected with each other, so that the signal lines M1 and Csel1 are shared, and the signal lines M2 and Csel2 are shared.
