Abstract
Disclosed is an ink jet printer having the capability of printing both vertically and horizontally. This is accomplished by mechanical orientation of the electric field associated with the deflection plates. In a first embodiment, the plates are mounted in such a manner as to permit rotation manually, for example, by a handle which interconnects the two plates and permit rotation thereof about the axis of the ink drop stream. In an alternate embodiment, the deflection plates are comprised of two pairs, a horizontal pair and a vertical pair which are shiftable into and out of operating position to effect the desired ink drop deflection.
