Dot-matrix printer with impact force determination
 In a dot-matrix printer including a wire-dot print head having print wires which print dots by impact on a printing medium, and a sensor for sensing the position of the print wires and generating signals indicating the position of the print wires, a parameter is set to determine a printing force with which each of the print wires impacts the printing medium. A control and driving circuit drives the print wire responsive to the signals from the sensors and the set parameter. The combination of the feature of setting a parameter for controlling the printing force and the feature of detecting the position of the print wire enables the control over printing force with a high reproducibility. So printing with an optimum printing force is ensured.
