A low-temperature-slush-fluid producing apparatus capable of achieving an increased weight solidification rate of slush fluid is provided. The support structure may be a submount with the LED dice already electrically connected to leads on the submount. The data driver supplies a plurality of data pulses to the plurality of the address electrodes and the timing controller controls a width of a first data pulse of the plurality of data pulses to be different from a width of a second data pulse of the plurality of data pulse. The air stream, however, does not disrupt the intended trajectory of the ink drops during printing. The invention further relates to a computer program product.
