Abstract
A second heating device heats an inner wall of an ink chamber of a print head to a temperature not lower than the melting point but not higher than evaporating temperature of ink 3, for a prescribed time period after the end of printing, based on a signal from a second heating control device. Consequently, the ink solidified and deposited on the inner wall of ink chamber and not used for printing is liquefied and recovered to the ink chamber to be used for the next printing.
