PRINTER AND PRINTING WITH BOUNDARY LAYER DISRUPTION

摘要

A printer for printing on a print medium includes a print module supporting at least one printhead having ink orifices formed in a front face thereof through which ink drops are ejected into a print zone between the printhead and the print medium during printing, and a member extending beyond the front face of the printhead toward the print medium from the print module adjacent the printhead, wherein the member disrupts a boundary layer of air in the print zone between the printhead and the print medium during printing.
