Abstract
A method of controlling noise in an impact printer that modulates the input pulse to the power amplifier of the printer. The resulting current waveform is then applied to the print wire solenoids. The final shape of the force input to the platen reduces or spreads the spectral envelope containing problem harmonics and acoustic output noise.
