Claim 3:
4. The thermal transfer printing apparatus according to claim 1, further comprising a drive roller, to drive the ribbon at a first speed on the coating zone, and wherein the first controller is configured to control the movement of each moving roller along their predefined trajectory to:
drive the ribbon on the printing zone at a speed inferior to the first speed by driving the pre-printing buffer to reduce the length of the ribbon from the coating device to the printhead and simultaneously by driving the post-printing buffer to increase the length of the ribbon from the printhead to the coating device, and
drive the ribbon on the printing zone at a speed superior to the first speed by driving the pre-printing buffer to increase the length of the ribbon from the coating device to the printhead and simultaneously by driving the post-printing buffer to decrease the length of the ribbon from the printhead to the coating device.
