ABSTRACT:
The invention relates to a recording or printing device utilizing a jet of liquid, which device comprises a carriage which may be displaced in a direction of movement parallel to the printing medium. This carriage carries a nozzle which discharges a jet of ink which is divided into a series of droplets, the dots formed by the impingement of these droplets on the printing medium making it possible to obtain images formed by dot. In order to avoid smearing of the image formed by the dots several techniques are disclosed which compensate for the relative movement between the carriage and the paper or printing medium, thereby making the path of the droplets more nearly perpendicular to the paper. In one embodiment, for example, the carriage carries electrodes which have the role of deflecting the orientation of the jet of liquid dispatched by the nozzle, in the opposite direction to that of the movement of the carriage.
