摘要：
A method of printing and a printhead are provided. The printhead includes a nozzle array having a width; a gas flow source; and a gas flow duct in fluid communication with the gas flow source. The gas flow duct includes an expansion region and a compression region. The expansion region of the gas flow duct gradually expands along its cross sectional length to at least the width of the nozzle array. The compression region of the gas flow duct gradually contracts along its cross sectional length.
