PROBLEM TO BE SOLVED: To provide an inkjet recorder capable of enhancing printing quality at a peripheral portion of a bar of a barcode. SOLUTION: When the ambient temperature is higher than 25°C, three ink droplets are ejected from a nozzle 31 per print data of one dot to print one dot. When the ambient temperature is not higher than 25°C, three ink droplets of which the volume is smaller than that of the three ink droplets at the temperature higher than 25°C, are ejected. After the first ink droplet Q1 is ejected, a cancel pulse is not applied, and then the second ink droplet Q2 is ejected immediately so that the second ink droplet is united with the first ink droplet Q1 to form a new ink droplet Q12 before the first ink droplet Q1 arrives at print paper P. As the ink droplet Q12 has the total volume of ink droplets Q1, Q2, the flying speed is not degraded, and then the deviation of the arrival position can be reduced. As a result, extension of a peripheral portion of a bar in a sub-scanning direction can be reduced. COPYRIGHT: (C)2007,JPO&INPIT
