Abstract: In a printing method using an ink jet head unit including a plurality of ink jet heads disposed in a horizontal direction over an object in which each of adjacent end portions of the plurality of ink jet heads has more than one overlapped nozzle, a supply of droplets from each of the nozzles of the plurality of ink jet heads may be identified. A combination of supplies of the droplets from the nozzles of the plurality of ink jet heads may be determined to form a desired pattern on the object. The desired pattern may be formed on the object using the plurality of ink jet heads including the nozzles arranged in accordance with the determined combination of the supplies of the droplets.
