Abstract
A dot impact printing head for a printing apparatus that performs printing on a medium by repeating transport of the medium in a sub-scanning direction and movement of the dot impact printing head in a main scanning direction that intersects the sub-scanning direction, the dot impact printing head including at least one wire pin row formed as a result of a plurality of wire pins being arranged at a fixed pitch in the sub-scanning direction, in which all of the wire pins that configure the wire pin row are disposed shifted in three or more different positions in the main scanning direction within a range of the same dimension as the pitch.

A dot impact printing head for a printing apparatus that performs printing on a medium by repeating transport of the medium in a sub-scanning direction and movement of the dot impact printing head in a main scanning direction that intersects the sub-scanning direction, the dot impact printing head comprising:
- at least one wire pin row formed by a plurality of wire pins being arranged at a fixed pitch in the sub-scanning direction,
- all of the wire pins that form the wire pin row being shifted from each other in three or more different positions in the main scanning direction, with the all of the wire pins being disposed within a range that is smaller than or equal to the fixed pitch, the three or more different positions being disposed at equally spaced intervals in the main scanning direction.
