ABSTRACT:
Disclosed is an impact dot head and an impact dot printer provided as not causing wire breakage by supporting a wire performing a printing operation so as to be resiliently oscillatable in a printing digit direction even if the impact dot head starts printing from a position outside a printing sheet due to erroneous setting of a printing area and therefore passes an end of the printing sheet while performing the printing operation.
