[0002] With the development of logistics and other industries, the demand for labels is also increasing. The traditional label paper is composed of a face material and a bottom paper. When used, the face material is peeled off from the bottom paper and pasted to the pasted object. After the label is used, the remaining bottom paper has no use value, which not only causes waste of resources, but also causes environmental pollution. To solve this problem, no bottom paper printers for printing no bottom paper labels with only a face material have appeared on the market. The current no bottom paper printers usually set an anti-sticking rib in the paper passage or adopt a multi-roller structure to form a multi-layer paper guide structure, so that the printer can output paper at a specific angle to avoid paper jamming in the paper passage. However, the anti-sticking rib still causes residual adhesive on the passage, which still causes paper jamming. Moreover, the multi-roller structure makes the structure of the printer complex, which increases the failure rate of the machine. SUMMARY

As preferred, C=80°. As an example of a specific embodiment, the diameter of the new paper roll 11 is 8.2 cm, and the included angle between the main plane of the support plate 332 and the first direction is 48°.

[0067] Specifically, the first limiting block 6 is slidingly connected with the paper guide plate 5 and has a first state of moving relative to the paper guide plate 5 and a second state of being fixed in position relative to the paper guide plate 5. As a feasible implementation form, the first limiting block 6 is kept in position by the friction force between the first limiting block 6 and the paper guide plate 5, and an operator needs to exert an external force to overcome the friction force, so as to adjust the interval distance between the first limiting block 6 and the second limiting block.
[0068] For the first limiting block 6 and the second limiting block, a push plate 61 is arranged on the limiting block in sliding connection with the paper sheet plate 5, and an operator is adapted to adjust the position of the limiting block on the paper sheet plate 5 through the push plate 61, thereby facilitating the operation convenience.

[0077] Further, the paper tearing cutter 7 is arranged on one side of the paperless label curling side, so as to replace the easy-to-stick surface of the shell 1 at the paper outlet 8, which can directly avoid the adhesive surface of the paperless label from contacting the shell 1, and is beneficial to simplify the structure of the paper outlet 8.
