The user can also assemble the small bin 1 with the large bin 2, place small-sized printing paper in the small bin 1, and supply printing paper through the small bin 1 to realize printing operation. In this way, the user can switch the placement space according to the printing needs through the assembly and disassembly of the small bin 1 to meet the placement of printing papers of different specifications, thereby realizing different printing needs. A single printer can meet the switching of two specifications of printing paper for printing operations, thereby reducing the user's printing cost and improving the practicality of the printer, so that the printer can meet the thermal printing operations of printing papers of different specifications.

[0027] The large bin 2 is suitable for printing paper with a specification of 80, and the small bin 1 is suitable for printing paper with a specification of 58.

[0028] Of course, the large bin 2 can also be used for printing papers of other specifications, and the small bin 1 can also be used for printing papers of other specifications; the specifications of printing papers applicable to the large bin 2 and the small bin 1 are different, so that switching between printers of different specifications can be achieved.

[0029] The machine body has a paper guide groove, which is connected to the large bin 2. The large bin 2 supplies printing paper to the paper guide groove, and outputs it through the paper guide groove; when the small bin 1 is assembled, the paper guide groove is connected to the small bin 1, and the small bin 1 supplies printing paper to the paper guide groove, and outputs it through the paper guide groove.

[0040] Furthermore, a paper guide 15 is formed at the end of the small bin plate 13. The paper guide 15 is embedded in the machine slot 3. The paper guide 15 extends toward the roller axis. The paper guide 15 is used to guide the printing paper to the roller axis. Under the action of the paper guide 15, it plays a guiding role when the paper is discharged, making it easier for the roller to roll up the printing paper, thereby facilitating the supply of the printer.
