<P>PROBLEM TO BE SOLVED: To form high-quality dots in a short drive cycle in an inkjet printer. <P>SOLUTION: In an inkjet printer, for forming a large dot on a sheet of recording paper during image recording, a second ejection pulse 721 and a first ejection pulse 713 are selected from a basic waveform 70, as a driving signal. For forming a medium dot, a first minute pulse 711 and the first ejection pulse 713 are selected. For forming a small dot, a third ejection pulse 722 is selected. Upon non-ejection of liquid droplets, a second minute pulse 712 is selected. As a result, by adjusting the waveform of the first minute pulse 711, high-quality dots of respective sizes can be formed while shortening a driving cycle with the use of the first ejection pulse 713 for forming a large dot and a medium dot. <P>COPYRIGHT: (C)2013,JPO&INPIT |
