The invention discloses a signal synchronization tapping plate for an ink jet printer and a signal transmission method. The tapping plate is characterized in that one end is provided with a receiving port for receiving a detection signal, and the other end is provided with an output port connecting nozzle control boards for outputting a detection signal; the interior of the tapping plate is provided with an FPGA which divides the received detection signal into at least two detection signals with the same channel at the same time in a tapping manner; the output port transmits the detection signals with the same channel after tapping to at least two nozzle control boards in a synchronous and parallel manner, so as to control the nozzle to print. The tapping plate divides the detection signal into multi-channel signals in a tapping manner, and can be connected with the plurality of nozzle control boards at the same time, thereby controlling more nozzles to print. The different mode of arrangement of the nozzles can increase the printing width, printing speed and printing resolution or achieve the multi-color printing. Meanwhile, the nozzle control boards are used for receiving the signals synchronously, thereby avoiding printing lag of a certain nozzle caused by signal asynchronization, and protecting printing quality from being affected.
