<p>A fluid spraying head (1) for an ink jet printing device includes a plurality of drop generating elements which are connected to flexible ducts, which in turn are connected to fluid jet nozzles. The fluid jet nozzles are displaceably arranged in respective slots of first and second guiding members (5, 7). The height or size of printing patterns generated by the fluid spraying head onto an object which is moved relative to the fluid spraying head can be varied by changing the relative position of the first and second guiding member (5, 7) with respect to each other.</p> |
