<p>PROBLEM TO BE SOLVED: To prevent a printer controller preventing density unevenness from occurring and causing granularity not to be deteriorated.SOLUTION: A printer controller uses a recording head disposed with a plurality of nozzles individually communicating with predetermined ink flow passages and being disposed in rows, individually supplies predetermined driving electric power to actuators disposed in the individual ink flow passages, causes ink droplets to be discharged from the individual nozzles and can discharge the ink droplets at different discharge speeds such that posterior ink droplets catch up with anterior ink droplets and are integrated therewith before the ink droplets prior to continuous discharge land on a printing medium. The printer controller is provided with control means driving the actuators of the recording head such that dots of a region where a nozzles usage rate is greater than a predetermined threshold value are printed by causing the ink droplets obtained by integrating the ink droplets continuously discharged in air to adhere to the printing medium.</p> |
