Abstract (en)
[origin: EP0387079A1] A divisional step dot printing device has a plurality of dot pins (P1-P24) of its dot printing head (22) divided into a plurality of groups (G11,G12,G21,G22,G31,G32) each containing a sequence of adjacent dot pins. The device 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 (G11,G12,G21,G22,G31,G32) of dot pins which extend over both sides of the centre line of the printing head (22) in the direction of the axis of the platen (11).
