Apparatus for controlling ink in an ink jet printer includes an ink delivery channel; a source of pressurized ink communicating with the ink delivery channel; a nozzle bore which opens into the ink delivery channel to establish an ink flow path, the nozzle bore defining a nozzle bore perimeter, inherent surface tension of pressurized ink in the nozzle bore forming an ink meniscus; and a selectively-actuated heater associated with the nozzle bore to cause a reduction in the surface tension of the ink when activated such that ink flows from the nozzle bore in a continuous stream substantially for the duration of activation of the heater only.
