The printhead assembly P1 and the drive roller assembly P2 cooperate to move the printing paper and perform printing operations on the printing paper. The printing paper is, for example, common roll label printing paper. A detailed description will follow with reference to the illustrations. For ease of explanation, the X direction in the illustrations represents the printer's direction from right to left, the Y direction represents the direction from back to front, and the Z direction represents the direction from bottom to top.

[0021] [Main Body] The main body 1 includes a base 1A and a top mount 1B. The top mount 1B is mounted on the base 1A. The base 1A is equipped with a control panel 5, a power supply assembly (not shown in the figure), and other structures. The printhead assembly P1 is mounted on the main body 1. It can be a common thermal printhead assembly, which will not be described in detail.

[0022] Combination Figure 3From a downward viewing angle, the outer periphery of the top mount 1B extends beyond the outer periphery of the base 1A, meaning the outer periphery dimension of the top mount 1B is larger than that of the base 1A. This design reduces the likelihood of water droplets or flow entering the joint between the top mount 1B and the base 1A during rainy weather when used outdoors. Figure 5 The base 1A and the top seat 1B are joined together. One of them (such as the base 1A) may have a rib M, and the other (such as the top seat 1B) may have a groove (not shown) that matches the rib M. By embedding the rib M into the groove, the waterproofness of the joint between the top seat 1B and the base 1A can be improved.

[0023] The top seat 1B has a mating opening S that matches the outer circumferential dimensions of the cover 2, for connection. Figure 4 and Figure 5 The cover 2 moves closer to or further away from the joint S by flipping relative to the body 1.
