Abstract:
1. A printer, comprising: a DC power source; an electronic controller for controlling operations of the printer including a printing mechanism of the printer; a power control circuit connected between the DC power source and the electronic controller for controlling delivery of DC power to the electronic controller, the power control circuit comprising: a switch condition feedback path from the power control circuit to the electronic controller for providing a switch closed signal to the electronic controller when the user closeable switch is closed; a control path connected between the electronic controller and the latching circuitry; when the power control transistor is in its ON state and the electronic controller is receiving DC power, the electronic controller responds to receipt of a switch closed signal by modifying an output on the control path to cause the latching circuitry to unlatch into a non-conducting state thereby eliminating the voltage condition and placing the power control transistor in its OFF state.
