Abstract
A head for an ink-on-demand jet dot printer is highly integrated to provide a large plurality of closely spaced dots by combining more than one head of lesser dot density as components of a single unit. The dots from the separate component heads are interspaced on the print recording medium to provide characters of high quality. Commonality of elements provides for a miniaturized head. In another embodiment independent pressure chambers, channels and nozzles are formed on opposite sides of a common baseplate.
