1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a method of preventing curling of a thermal recording paper by which the thermal recording paper is unfolded by the thermal recording head without using a device for unfolding the thermal recording paper before and after the printing operation.;2. The technical problem to be solved by the invention;The present invention provides a method of preventing curling of a thermal recording paper which does not use a paper guide to prevent curling of the thermal recording paper.;3. Summary of Solution of the Invention;The present invention provides a method of preventing curling of a thermal recording paper used in a printing apparatus having a recording tray, a thermal recording head, and a platen roller, wherein the thermal recording paper is wound in a counterclockwise direction so that the surface coated with the thermal liquid is placed on the inner surface. A first process, a second process of mounting the thermal recording paper so that an end surface of the thermal recording paper is placed at a lower end of the recording tray, a third process of rotating the thermal recording paper clockwise during a printing operation, and received data Is printed on the inner surface of the thermal recording paper, and the fourth process of preventing the thermal recording paper from curling by heat generated from the heating line of the thermal recording head TTP, and printing by the pressure of the spring and the rotation of the platen roller. And a fifth process of transferring the thermally sensitive recording paper to the outside.;4. Important uses of the invention;The present invention does not use a paper guide to prevent curling of the thermal recording paper, so that the thermal recording paper is unfolded by heat radiating to the thermal recording head, thereby preventing scratches on the thermal recording paper, and on the inner surface of the thermal recording paper. It is possible to prevent discoloration and damage due to the application of the heat-sensitive liquid, and to prevent the increase and reduction of the quality of the thermal recording paper by preventing the pressure of the spring by not installing the paper guide, and to reduce the cost. In addition, the user can eliminate the inconvenience and the natural progress of the thermal recording paper to prevent the jam due to the curl of the thermal recording paper, the printing operation of the printing device inhibited by jamming the thermal recording paper (jam) Occurrence), and the shape of the product can be miniaturized to have an aesthetic effect.
