Embodiment Construction
[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0030] figure 1 is a structural sectional view of the thermal printer according to the first embodiment of the present invention. Such as figure 1 As shown, the thermal printer includes a frame 1, a printing mechanism 2, a paper feeding mechanism 3, a detection mechanism 4, a separation mechanism 5, and a power supply and a driving mechanism (not shown in the figure).
[0031] The frame 1 is provided with a paper inlet 11 and a paper outlet 12. The direction of thermal paper moving from the paper inlet 11 to the paper outlet 12 is the paper feeding direction, and the direction of moving from the paper outlet 12 to the paper inlet 11 is It is the paper unwinding direction. During the printin...

The invention discloses a thermo-sensitive paper conveying method of a thermal printer and the thermal printer. The thermal printer comprises a printing mechanism used for printing on thermo-sensitive paper. The printing mechanism comprises a rubber roll and a printing head which are arranged in a tangent manner. The thermo-sensitive paper conveying method comprises the steps that when printing is conducted, the thermo-sensitive paper is conveyed to the position between the rubber roll and the printing head in the paper feeding direction so that printing can be conducted on the thermo-sensitive paper; after printing is finished, the thermo-sensitive paper is conveyed in the paper exiting direction until the thermo-sensitive paper is disengaged from the printing position, and the printing position is the position where the rubber roll and the printing head are tangent. By means of the thermo-sensitive paper conveying method of the thermal printer and the thermal printer, the problem that as the thermo-sensitive paper is pressed between the printing head and the rubber roll for a long time, the printing effect of a thermal printer is affected in the related technology is solved.
Description
technical field [0001] The invention relates to the field of printing, in particular to a method for conveying thermal paper of a thermal printer and the thermal printer. Background technique [0002] Thermal printers are widely used in supermarkets, shopping malls, telecommunications, hospitals and other fields, using thermal roll paper as the printing medium to print transaction vouchers for customers. The thermal paper is formed by stacking base paper, base coat, thermal coating, and protective layer in sequence, and the continuous thermal paper is wound on the core tube to form a thermal roll paper. [0003] When the thermal printer prints, the thermal paper is drawn out from the paper roll and passes between the tangentially set print head and the rubber roller. The protective layer of the thermal paper is in contact with the print head, and the base paper of the thermal paper is in contact with the rubber roller. The driving mechanism of the printer drives the rubber ...
