Abstract
An ink-jet recording apparatus quickly completes a preparatory driving operation, and suppresses the wasteful consumption of the ink even if the apparatus is used in a cold environment after the apparatus has been held inoperative for a long time. The ink-jet recording apparatus comprises a first storage for storing a first driving pulse width data, a second storage for storing a second driving pulse width data, and a plurality of driving pulse generating units. A data selecting unit selects either the first driving pulse width data or the second driving pulse width data according to selection data set by a dot counter control unit, and a print pulse width setting unit and the driving pulse generating units generate ink-jet print head driving pulses. A print data processing unit produces print data for driving the nozzles of the ink-jet print head. The first and second driving pulse width data is used selectively and the print data is produced according to the time for which the ink-jet recording apparatus has been held inoperative and the temperature of the ink-jet print head.
