Method of reducing drive energy in a high speed thermal ink jet printer

摘要: A thermal ink jet printer including a printhead having plurality of drop firing resistors responsive to pulse groups wherein group includes one or more pulses sufficiently closely spaced produce respective droplets which merge in flight form an whose volume depends on the number group. The are controlled such that energy second and successive is less than first pulse. intervals between leading edges can be constant reduced adjacent beginning with interval pulses.
