Description

Technical Field

[0001] The utility model relates to the technical field of invoice printers, in particular to an invoice printer for convenience stores. Background Art

[0002] Receipt printers, as a difference from common office laser printers, are actually widely used in many occasions, such as printing receipts and invoices in shopping malls and supermarkets, and printers for printing value-added tax invoices in the finance departments of various companies, etc. In addition, there are many other uses: such as portable receipt printers used by traffic police to issue tickets on the spot, check printers used in finance, and convenience store invoice printers of existing technology are used to print invoices for customers when they check out.

[0003] However, the existing invoice printers for convenience stores have the following disadvantages:

[0004] (1) The existing invoice printers for convenience stores have a weak function of fixing invoice paper. When using them, cashiers need to put invoice paper into the printer in advance when printing invoices for customers. The printers in the prior art cannot fix the invoice paper well, which easily causes the invoice paper to fall off and jam. As a result, new printing paper needs to be installed when printing invoices for customers, causing inconvenience in work.

[0005] (2) Existing invoice printers for convenience stores have weak heat dissipation capabilities. When in use, a processor is usually installed inside the printer to perform printing work. The processor will dissipate heat over a long period of time, causing the printer to become stuck and not operate smoothly. Existing technologies usually provide heat dissipation slots on both sides of the printer body to dissipate heat, resulting in inefficient heat dissipation efficiency. Utility Model Content
