Abstract: Apparatus, systems and methods are provided for controlling energy consumption by a selectively enabled processing system, such as a high-density code scanner. The selectively enabled processing system has at least one high-power consumption microprocessor which does not include a low-power consumption mode. Also included are a power-supply, a switch and a trigger for turning ON and OFF the power-supply, and means for performing diagnostics. The performing diagnostics means operate on at least a portion of the selectively enabled processing system whenever the power-supply is initially switched ON, and inhibit the power-supply upon diagnostics completion. The trigger selectively enables means for causing the microprocessor to consume the power-supply for a pre-set time period while processing, and then inhibit the power-supply upon expiration of the time period without re-performing diagnostics.

Abstract: The present invention is equipped with a plurality of print buffers for inputting print data into a thermal head, wherein such print data are selectively fed to simply change the current on-time for energizing the heating elements of the thermal head relative to specific information out of the entire information to be printed, so that the specific information is printed emphatically in a particular color to become conspicuous, and simultaneously the contour of each specific character is edged in a basic color to be distinctly legible. Such edged print is attained by utilizing the gradient of the temperature distribution induced in the heating elements by the current on-time control system, hence eliminating the necessity of any edging print data to consequently simplify the control.
