    摘要： An inkjet printer includes a printhead having a plurality of ink orifices formed therein. During printing, ink drops are ejected through the ink orifices into a print zone between the printhead and a print medium with an intended ink drop trajectory toward the print medium. An air movement system directs an air stream to the print zone substantially parallel to the intended ink drop trajectory as the ink drops are ejected during printing so as to affect air currents acting on the ink drops during printing and prevent print defects caused by the air currents. The air stream, however, does not disrupt the intended trajectory of the ink drops during printing.

    摘要翻译： 喷墨打印机包括其中形成有多个墨孔的打印头。 在打印期间，墨滴通过墨水孔喷射到打印头和打印介质之间的打印区域中，具有朝向打印介质的预期墨滴轨迹。 空气运动系统在印刷期间喷墨时基本平行于预期的墨滴轨迹将空气流引导到打印区域，以便影响在打印期间作用在墨滴上的气流，并防止由气流引起的打印缺陷 。 然而，空气流在打印期间不会破坏墨滴的预期轨迹。

    摘要： 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.
