Abstract

A divisional step dot printing device for a wire dot printer in which a plurality of dot pins of the dot printing head is divided into a plurality of groups of a sequence of dot pins and is driven in a sequence of divisional dot printing steps. Each of the divisional dot printing steps is carried out by a combination of groups of dot pins which substantially cover the center line of the platen.
