PROBLEM TO BE SOLVED: To provide a method for reliably preventing occurrence of change in the viscosity of ink inside a nozzle of a print head, the change obstructing jetting of ink droplets after the interruption of printing is ended, the interruption in which a printed article is decelerated from a printing speed and then re-accelerated to the printing speed.SOLUTION: When a printing timing pulse (T) is generated during interruption of a printing operation, a printer control part (2) triggers an oscillation before loading print data (DA) corresponding to the printing timing pulse (T) to at least one print head (5), to transmit a print start signal (SA) to the aforementioned print head, and, therefore transmits at least one oscillation pulse (V) to the at least one print head (5). |
