Abstract
Provided are a control device of an ink circulation device, a control method of an ink circulation device, a program, and a printing device that suppress a pressure fluctuation of an ink circulating in an ink jet head regardless of an operation state. Parameters of a PID control of an upstream side pump that supplies an ink stored in an ink tank to an ink jet head are switched between a jetting state in which the ink is jetted from the ink jet head and a non-jetting state different from the jetting state, and in a case in which, in the upstream side pump in the non-jetting state, proportional gain is denoted by Kp1_in, integral gain is denoted by Ki1_in, and differential gain is denoted by Kd1_in, and, in the upstream side pump in the jetting state, proportional gain is denoted by Kp2_in, integral gain is denoted by Ki2_in, and differential gain is denoted by Kd2_in, relationships of Kp1_in <Kp2_in, Ki1_in>Ki2_in, and Kd1_in<Kd2_in are satisfied.
