[0002] Many labels must be able to stand the test of time; they must not deform for a long time, the text must be preserved for a long time, they must not fade, they must not wear out due to contact with solvents, or deform or discolor due to high temperatures, etc. Therefore, it is necessary to use a special printing medium and printing material to ensure these characteristics. General inkjet printing technology cannot achieve this, laser printing cannot achieve this, and the effect of needle punching cannot meet the requirements of the original design, so thermal transfer technology came into being.
[0003] Thermal transfer technology, in simple terms, uses a special carbon ribbon to transfer the toner coating on the carbon ribbon to paper or other types of materials by heating. The printed paper and carbon roll need to be placed separately. Existing thermal transfer printers lack limiters for the carbon roll and paper, which may cause the printing position to shift and affect the print quality. At the same time, after the carbon roll is replaced, it needs to be rotated and reeled before it can be tightened, causing waste. For this reason, we propose a thermal transfer printer.
