Synchronization printing heat transfer printing coding machine and synchronization printing method

The invention provides a synchronization printing heat transfer printing coding machine and a synchronization printing method. The coding machine comprises a printing body, a power source case and a controller; through assorted mechanization and software support, the longitudinal printing quality is controlled by the density of printing heads, and the transverse printing quality is controlled by relative motion of the printing heads and a printing substrate. The synchronization printing technology used at the position is characterized in that the transverse printing effect is effectively controlled in the relative motion process of the printing heads and the printing substrate, and the printing quality is guaranteed. By means of the synchronization printing heat transfer printing coding machine and the synchronization printing method, it is guaranteed that the printing quality is attractive; in particular, when one-dimensional and two-dimensional bar codes are printed, the readability of the bar codes can be guaranteed, and colored tape can be effectively used.
