1. A light emitting control device for a light emitting diode print head comprising:

  • a control unit;

    a pulse-mask unit, controlled by the control unit, outputting n clock signals in sequence to the light emitting diode print head, n being a positive integer;

    a strobe unit, controlled by the control unit, outputting a strobe signal to the light emitting diode print head to switch on the light emitting diode print head; and

    a data output unit, controlled by the control unit, outputting a print data signal to the light emitting diode print head;

    wherein when the pulse-mask unit outputs a k-th clock signal of the n clock signals, the pulse-mask unit delays the k-th clock signal for a predetermined time, and the data output unit pauses outputting the print data signal, after the predetermined time, the pulse-mask unit and the data output unit continues to output the rest of the clock signals and the print data signal, k is a positive integer smaller than or equal to n.
