In order to prevent a viscosity of ink near each nozzle orifice of a recording head from increasing, a time to eject an ink drop therethrough is analyzed based on print data. Dot pattern data is generated by determining the printing period where the fine vibration should be applied to the meniscus of ink in each nozzle in accordance with analysis of the print data. Accordingly, remarkable suppression of the viscosity increase, stabilization of the flying path of the ink drop, and efficient flushing may be achieved without complexity of the whole machine construction. <IMAGE> |
