A printhead is used to eject printing fluid, such as ink, onto a printing medium. This printhead has an orifice plate defining plural orifices from which the printing fluid is individual ejecting into the printing medium to form characters and images. This orifice plate includes in addition to the plural orifices, plural barrier walls interdigitated with the orifices so that each orifice is between a pair of spaced apart barrier walls. The barrier walls substantially prevents the ejection of printing fluid from one selected orifice from causing an unwanted ejection of printing fluid from adjacent orifices.
