Abstract:
A dot recording apparatus for recording dots on a surface of a printing medium with a dot recording head, the dot recording apparatus comprising:a dot-forming element array arranged on the dot recording head to face the printing medium, the dot-forming element array comprising a plurality of dot-forming elements for forming a plurality of dots of an identical color at a substantially constant pitch in a sub-scanning direction; a main scan driving unit that drives at least one of the dot recording head and the printing medium to carry out main scan; a head driving unit that drives at least part of the plurality of dot-forming elements to form dots in a course of the main scan; a sub-scan driving unit that drives at least one of the dot recording head and the printing medium every time when the main scan is completed, thereby carrying out sub-scan; and a control unit that controls the above units; wherein the control unit comprises: a recording mode storage unit that stores a plurality of dot recording modes having a substantially equal recording speed, as alternative dot recording modes each defining operations of the main scan and the sub-scan for recording dots at an identical recording resolution; a mode selection information setting unit, in which mode selection information is set to specify a desired dot recording mode among the plurality of dot recording modes; and a unit that executes the dot recording according to the desired dot recording mode specified by the mode selection information.
