A paper feeding precision calibration method and calibration system. In the calibration method, the paper feeding distance is corrected by correcting the number of micro steps comprised in a full step. By adoption of the technical solution, each full step can be compensated, and printing content data is segmented according to each full step, so that the uniformity of printing content can be ensured, local elongation or compression can be effectively avoided, and excellent printing quality can be ensured. In summary, by adoption of the technical solution, calibration compensation can be performed on the paper feeding precision problem caused by the outer diameter error of a rubber roller, and the manufacturing difficulty of a printer is reduced; moreover, the worn or aged rubber roller can also be calibrated, thereby extending the service life of the rubber roller. In addition, for the paper feeding precision problem caused by changes in the thickness and friction coefficient of paper itself, the paper feeding precision of the printer can also be recovered by the technical solution.

A thermal transfer printer and a composite consumable thereof and a method for supplying such composite consumable to the thermal transfer printer are disclosed. The consumable supplying device is installed with a composite consumable which is made by winding a thermal transfer ribbon and a printing media together around a common core with the ink side of the thermal transfer ribbon facing the surface of the printing media. Accordingly, just one consumable supplying device rather than two different consumable supplying devices as in existing thermal transfer printers should be arranged to provide the thermal transfer ribbon and the printing media to the thermal transfer printer at the same time. In such a way, the internal space of the thermal transfer printer can be effectively saved, which significantly reduces the volume of the thermal transfer printer.

A thermal print head, comprising an infrared radiation layer (2) made of an infrared radiation material and used for radiating heat to print media in the mode of thermal radiation. Therefore, the thermal print head can heat print consumables in the mode of infrared radiation. Infrared radiation heating needs no heat transfer medium, and features high penetrability, the capability of simultaneous internal and external heating, and a quick heating speed. In addition, the infrared absorption rate of a heating object is high enough, and the heating object can reach a temperature close to that of an infrared radiation source in a short time. The thermal print head configured in this way effectively improves the printing speed, and greatly reduces the printing energy consumption as well as the mechanical loss and manufacturing difficulty and costs of the print head.
