A drop-on-demand ink-drop printer (as opposed to a continuous-droplet-stream printer) has a printhead through which ink flows continuously. In the vicinity of the orifice through which drops are expelled there is a constriction, for instance a Venturi tube, which (a) maintains a negative meniscus at the orifice, and (b) prevents any accumulation of detritus or gas at the orifice. The ink drop is expelled by some form of shock-wave producing means.
