A method and apparatus to perform a spitting service on a wide array print head includes detecting dot counts of print heads after a predetermined page is printed, determining spitting service levels corresponding to the detected dot counts, and executing spitting services for the print heads according to the spitting service levels. Accordingly, spitting services of a plurality of print heads of the wide array print head can be classified into several levels for execution, so that the print heads can maintain an optimum condition and provide a best printing quality, and unnecessary ink consumption can be reduced.
