A method and droplet selection device are provided for a continuous printer for selectively deflecting a droplet from a predetermined printing trajectory. In particular, a droplet selection device is provided for a continuous printer, comprising a droplet ejection system arranged to generate a continuous stream of droplets from a first fluid jetted out of an outlet channel; and a jet system arranged to generate a second jet for colliding the jet into the stream of droplets. The jet system comprises a deflector to selectively deflect the second jet into the continuous stream of droplets, so as to selectively deflect the droplets from a predefined printing trajectory.
