A method and apparatus which laterally focuses aqueous ink drops onto a substrate, using electric fields. The drops are not charged, and focusing results from the forces on the uncharged dielectric drop that occur in a nonuniform electric field. It is shown that initial lateral velocity misdirection of the drops is corrected using electric fields. Lateral velocities which would produce drop displacements of ~50 mum from their intended positions, at a height of 1 mm above the ink surface, may be corrected to produce displacements of less than 2.5 mum.
