Abstract:
1. A printing device, comprising: a mechanical energy storage mechanism configured to store a mechanical energy; an electric energy conversion mechanism configured to convert the mechanical energy into an electric energy; an electric energy storage device configured to store the electric energy that is provided from the electric energy conversion mechanism; a control unit configured to be operated by the electric energy, the control unit including a print-controlling device that is able to provide a printing data; a print head configured to be driven by the mechanical energy and to be provided with the printing data from the print-controlling device, the print-controlling device being configured to refer to a print head location which controls a timing for supplying the printing data and indicates a location for carrying the print head relative to an object; a carrying mechanism for carrying the print head, the carrying mechanism being configured to be moved by the mechanical energy; and a location detector for detecting the print head location relative to the object on which the print head prints a graphic or a character according to the printing data.
