Abstract
A printer for printing on a print medium includes a printhead having ink orifices formed therein through which ink drops are ejected into a print zone between the printhead and the print medium during printing, wherein the printhead has a scan axis oriented substantially perpendicular to a first column and a second column of the ink orifices and along which the printhead traverses during printing, and an air movement system directing a stream of gas to the print zone substantially parallel to the first column and the second column of the ink orifices and offset from and between the first column and the second column of the ink orifices as the ink drops are ejected during printing.
