Impact dot printing head control apparatus

Abstract

With an impact dot printing head control apparatus according to the invention, the drive control of respective wires is implemented on the basis of a normal fire and a pre-fire by generating the normal fire for driving the respective wires of the impact dot printing head so as to reach a printing position on the basis of printing data and a driving frequency of the impact dot printing head, and by generating, prior to the normal fire, the pre-fire for driving the respective wires so as not to reach the printing position. As a result, since the respective wires are caused to move by the pre-fire before actual printing operation by the normal fire even without preparing a large power source so as to meet requirements for driving the respective wires at the time of low temperature, the performance of the impact dot printing head can be ensured even at the time of low temperature, and in addition, reduction in product cost and downsizing of a product can be implemented.
