Abstract
An ink-jet printer for recording information by jetting ink droplets on a recording medium has a plurality of ink-jet nozzles arranged so that ink droplets projected therefrom combine in flight at a space between the nozzles and the recording medium. The amplitude and the pulse width of driving signals used to deflect piezoelectric elements which contract to expel the ink droplets from the nozzles are appropriately varied to vary the momentum of the individual ink droplets projected from each nozzle so that the combined ink droplets will have a velocity and direction representative of the information to be recorded.
