A heating device for recording heads of ink mosaic recorders, for maintaining the ink therefrom at an optimum temperature at time of discharge from the head. Means are provided for supplying heat to the head directly at the discharge orifices thereof. The device is further provided with control means, including temperature sensing means, for maintaining the temperature of the ink constant. Means are also provided for preventing operation of the recording head unless the ink is at its nominal operating temperature.
