A drop ejector (30) for ejecting discrete drops of liquid is disclosed. The drop ejector (30) includes a plurality of firing chambers (44), and each firing chamber (44) has an energy dissipation device (46). Each firing chamber (44) is associated with a fluid feed slot (42) configured to supply liquid to the firing chamber (44). A constricted inlet (50) is positioned between the firing chamber (44) and the fluid feed slot (42), through which liquid is drawn into the firing chamber (44) from the fluid feed slot (42).
