Multi-drop merge on media printing system

摘要

A printing method that includes supplying ink from an ink reservoir through an ink channel that connects the ink reservoir with ink ejection chambers formed on a first surface of a substrate. The ink channel is connected at a first end to the ink reservoir and at a second end to a separate inlet passage for refilling each of the ink ejection chambers with ink. A group of the ink ejection chambers in adjacent relationship forms one of a plurality of primitives on the first surface of the substrate in which only a maximum of one of the ink ejection chambers is energized at a time. An ejection element within one of the ink ejection chambers is energized to cause the plurality of ink drops to be ejected onto a media surface at a single pixel location in a single pass of the substrate over the media surface.
