Abstract
An ink jet recording apparatus wherein each dot, having the same size, may be formed regardless of whether print commands are successive. The ink jet recording apparatus includes a first drive waveform and a second drive waveform wherein the second drive waveform is used when there is no dot printed immediately before a dot is to be printed and the first drive waveform is used when there is a dot printed in response to a print command immediately before a dot is to be printed. Thus, regardless of whether the first drive waveform or the second drive waveform is used, the same volume of ink droplets are ejected and the same sized dots are formed.
