Abstract
An improved printer embodiment that includes a print head having thin 'foil' electrodes and associated spacers fashioned to maintain very precisely controlled dimensions and positioning according to specific, improved fabrication techniques providing an exactly oriented row of spaced, aligned electrodes. Each electrode includes an integral 'print-finger' adapted to resiliently skid over the passing print-substrate and, preferably, also including a companion contact adapted to engage an associated conductor terminal.
