In synchronous Rayleigh-type ink jet printing, charged ink droplets are directed to a recording medium along controlled trajectories to cause those ink droplets to strike the medium at desired locations. To encode the print medium with information, certain ones of droplets are diverted from the print medium to leave blank areas. One prior art ink jet printing architecture involves a drop charging technique wherein uncharged droplets strike a gutter for recirculating the ink droplets back to the drop generator and charged droplets are deflected in their trajectory away from the droplet gutter to strike the print medium.
