Thermal transfer coding machine realizing synchronous printing

The utility model provides a thermal transfer coding machine realizing synchronous printing. The coding machine includes a printing body, a power box and a controller, through matched machinery and software support, longitudinal printing quality is controlled by density of a printing head, and transverse printing quality is controlled by relative movement of the printing head and a printing substrate. The synchronous printing technology here effectively controls a transverse printing effect in a process of relative movement of the printing head and the printing substrate, thereby ensuring printing quality. The thermal transfer coding machine realizing synchronous printing can ensure beauty in printing quality, and particularly in printing one-dimensional and two-dimensional bar codes, can ensure readability of the bar codes and effectively utilize colored tapes.
