In an ink jet printer, a control unit converts externally provided printing data into jetting data associated with a size of dot to be printed. A drive signal generator generates a drive signal including a plurality of drive pulses. In a printing head, a pressure chamber is communicated with a nozzle. A pressure generating element varies pressure inside of the pressure chamber when at least one of the drive pulses is applied. A decoder decodes the jetting data into pulse select information in accordance with a predetermined conversion relationship. A switcher selects at least one of the drive pulses to be applied to the pressure generating element in accordance with the pulse select information. Pattern data defines the conversion relationship. A common signal line transfers the jetting data and the pattern data from the control unit to the printing head.
