Abstract
In a printing head of a printer with deviated continuous jet, one of the electrodes (2) for deviating the ink drops is provided in a downstream part with a longitudinal slit (12) presenting a plane of symmetry relative to a plane containing the axis of the ink jet.Thus the inter-electrode spacing can be reduced and the voltage present between the electrodes (2, 3) can be lowered without reducing the deflection efficiency.
