Supplying power to logic systems in printers

摘要

Power is provided from one portion of a printer, such as a printer electronics module, to another portion of the printer, such as a printhead. Logic signals produced in a first electronic module of the printer are transmitted to a second electronics module of the printer. A power signal is derived from the logic signals without interfering with the magnitude or duration of logic signals, and the logic power signal is applied to power the second electronic module without having a separate dedicated power line.
