[0002] An invoice printer is a device that is specifically used to print invoices. The working principle usually involves a print head transferring a ribbon or ink to paper in a specific way. For example, thermal transfer technology is a common printing method, in which the print head heats the ribbon, causing the pigment to melt and print on the paper. The specific printing process may include steps such as heating the print head, rotating the ribbon, and feeding the paper.

[0003] At present, after the invoice on the reel of the existing invoice printing machine is used up, the staff is first required to replace the invoice with a new roll of paper, and then pass the head end of the new roll of paper around the rollers on the invoice printing machine to achieve replacement. Before the old roll of paper is used up, the end of the old roll of paper and the head end of the new roll of paper can be manually bonded together with tape. However, manual operation is relatively inconvenient and requires the use of tools to complete, which is very inconvenient. Utility Model Content
