PROBLEM TO BE SOLVED: To provide an ink jet printing device capable of notifying ink replenishment to an ink chamber when the ink remaining amount of a tank is constant.;SOLUTION: The device stores an initial flag in which a first value corresponding to the execution of initial processing for filling a flow path from an ink chamber 111 to a recording part 24 and the non-executed state of ink replenishment or a second value corresponding to the execution of the initial processing and the executed state of ink replenishment, is set. The device carries out a first notifying process (S62) of notifying the necessity of ink replenishment when the count value of an ink amount discharged from a recording part 24 reaches a first discharge threshold value (S612: YES) in the set state of the first value in the initial flag (S611: first value), and a second notifying process (S62) of notifying the necessity of ink replenishment when the count value reaches a second discharge threshold value larger than the first discharge threshold value (S613: YES) in the set state of the second value in the initial flag (S611: second value).;SELECTED DRAWING: Figure 12;COPYRIGHT: (C)2019,JPO&INPIT
