摘要： There are provided a liquid jet head and so on capable of enhancing the convenience. The liquid jet head according to an embodiment of the present disclosure includes a jet section, a plurality of drive boards, at least one drive device, a waveform setting section, a control switch section, an external control line in which first control communication is performed, an internal control line in which second control communication is performed, and a plurality of drive control lines in which third control communication is individually performed. The waveform setting section generates second waveform configuration information for setting the drive waveform based on first waveform configuration information transmitted from the outside of the liquid jet head using the first control communication. The control switch section performs control switch between a transmission control action and a blocking control action when transmitting the second waveform configuration information, which is transmitted from the waveform setting section using the second control communication, to the drive device using the third control communication.
