<p>A printer of the dot matrix type has a series of hammers with pins that print on an underlying medium. The pins are released from magnetic retention by reversing the plurality of a permanent magnet. This is controlled by electro-mechanical drive circuits and logic circuits. The printer has a power supply which supplies an output of a voltage level for driving the electro-mechanical circuits connected to a ribbon drive, platen drive, paper feed, shuttle motor, and fans at a given voltage and the hammers at a different voltage. A thermal sensor is connected to a heat sink for power supply and the printer controller changes the rate of print when pre-established temperatures are sent.</p> |
