Abstract
An ink jet recording apparatus and printing control method are provided in which when a moving speed of a printing object is changed, a difference in writing start position is reduced and printing quality is improved. The apparatus includes an ink container, a nozzle connected to the container for ejecting ink, a charging electrode to charge the ejected ink, a deflecting electrode to deflect the charged ink, a gutter to collect ink not used for printing, a writing start timing control circuit to generate a first line clock signal, a printing width control circuit to generate a second line clock signal, and a control part. The control part controls print start timing based on the first clock signal, and when the printing object reaches the printing start timing, the control part performs a width adjustment of a character string of printing content based on the second clock signal.
