ABSTRACT:
A print head assembly having at least two print heads each having at least one nozzle for ejecting ink toward a print medium and being movable in a scanning direction substantially orthogonal to a conveyance direction of the print medium, is disclosed. The print heads are arranged in the scanning direction in such a manner that print time from at least one of the print heads is different from print time of at least one other print head. The nozzle interval between an adjacent pair of print heads has a value that is differentiated from the product of any natural number and the inverse number of a resolution, by, for example, adding to or subtracting the inverse number of the product of the resolution and a natural number other than 1, wherein the natural number is the number of print heads.
