Abstract
A printhead for an inkjet printer employs non-circular orifices, such as oval or parallelogram, at the surface of the orifice plate to increase the restoring force of the ink meniscus. The reduced tail and diminished spray of an ink droplet expelled from the non-circular orifice results in improved edge roughness and improved quality of print.
