[0002] Printers, such as portable printers, are small, lightweight printing devices often used in scenarios where printing is required anytime, anywhere, such as mobile sales, receipt printing, and warehouse management. Due to their portability, they typically have a compact size and lightweight design, making them easy to carry and use.

[0003] When a printer is in use, the label paper is printed by the print head and then output through the paper output channel. For some printers, there is a height difference between the print head and the inlet end of the paper output channel, which can prevent the label paper from being output smoothly.

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0066] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0067] Please see Figures 1 to 12 This application provides a printer 1, which includes a printer body 2 and a consumable cartridge 3 located within the printer body 2. The printer 1 has a paper output channel 11, which has a paper inlet 111 and a paper outlet 112. The consumable cartridge 3 contains a label paper roll 31. After printing, the label paper 311 on the label paper roll 31 enters the paper output channel 11 through the paper inlet 111 and is then conveyed to the outside of the printer 1 via the paper outlet 112. In some embodiments, the paper output channel 11 includes a first paper output channel 212, and the printer body 2 is provided with the first paper output channel 212. After printing, the label paper 311 is conveyed to the outside of the printer 1 through the first paper output channel 212. In other embodiments, the paper output channel 11 includes a first paper output channel 212 and a second paper output channel 331. The printer body 2 is provided with the first paper output channel 212, and the consumable box 3 is provided with the second paper output channel 331. After printing, the label paper 311 is conveyed to the outside of the printer 1 through the second paper output channel 331 and the first paper output channel 212 in sequence.

[0068] Combination Figures 1 to 5 The printer body 2 has a first surface 2a, a second surface 2b, and a third surface 2c opposite to the second surface 2b. The first surface 2a connects the second surface 2b and the third surface 2c, and the paper output port 112 is disposed on the first surface 2a. The printer body 2 includes a print head 23, which has a print surface 23a. Print lines 2311 are disposed on the print surface 23a. The projection of the print lines 2311 in a preset reference surface is located on the side of the projection of the paper output port 111 in the preset reference surface that is closer to or farther from the second surface 2b. The preset reference surface is parallel to the first surface 2a. In the first direction x, the print surface 23a is inclined relative to the second surface 2b, and the first direction x is perpendicular to the first surface 2a.

[0069] Since the projection of the printing line 2311 in the preset reference plane is located on the side of the projection of the paper inlet 111 in the preset reference plane that is closer to or farther from the second surface 2b, that is, the printing line 2311 and the paper inlet 111 have a height difference in the preset reference plane. Designed in the first direction x perpendicular to the first surface 2a, the printing surface 23a is inclined relative to the second surface 2b, which can adjust the tilt angle of the output direction of the label paper 311 relative to the second surface 2b, which is conducive to the label paper 311 crossing the height difference to reach the paper inlet 111 of the paper output channel 11, which is conducive to smooth paper output.

[0070] Next, see Figures 1 to 12 The printer body 2 will be described in detail.

[0071] See Figures 8 to 12 The printer body 2 has a first receiving cavity 211. The printer body 2 includes a drive shaft 22 located at least partially within the first receiving cavity 211. The drive shaft 22 extends along the depth direction z of the first receiving cavity 211. The consumable cartridge 3 is placed in the first receiving cavity 211, and the spool of the ribbon roll 32 inside the consumable cartridge 3 is sleeved on the drive shaft 22. In this way, the consumable cartridge 3 can be designed to be flat along the axial direction of the spool of the ribbon roll 32, and the printer body 2 can be designed to be flat along the depth direction z of the first receiving cavity 211, thus compressing the volume of the consumable cartridge 3 and the printer body 2; and enabling the printer 1 to be used either on a table or by hand.

[0072] The printer body 2 has a first surface 2a, a second surface 2b, a third surface 2c, a fourth surface 2d, a first end face 2e, and a second end face 2f. The first surface 2a, the second surface 2b, the third surface 2c, and the fourth surface 2d are all parallel to the depth direction z of the first receiving cavity 211. The first surface 2a and the fourth surface 2d are arranged opposite each other, the second surface 2b and the third surface 2c are arranged opposite each other, and the first end face 2e and the second end face 2f are arranged opposite each other in the depth direction z of the first receiving cavity 211.

[0073] The printer body 2 can be roughly rectangular. The first surface 2a, the second surface 2b, the third surface 2c and the fourth surface 2d are all connected between the first end face 2e and the second end face 2f. The first surface 2a is connected between the second surface 2b and the third surface 2c, and the fourth surface 2d is connected between the second surface 2b and the third surface 2c.

[0074] The first paper output channel 212 has a first paper inlet 2121 and a first paper outlet 2122. The first paper inlet 2121 communicates with the first receiving cavity 211, and the first paper outlet 2122 is disposed on the first surface 2a. The first paper outlet 2122 extends along the depth direction z of the first receiving cavity 211. The first paper outlet 2122 constitutes the paper outlet 112 of the paper output channel 11 of the printer 1. Thus, if the printer 1 is used on a desktop, the third surface 2c can be placed on the desktop, so that the first surface 2a is located to the side, and the first paper outlet 2122 is located to the side. When the label paper 311 is output from the first paper outlet 2122, the label paper 311 is output towards the side of the printer 1, and the side of the printer 1 is unconstrained, which will not cause paper accumulation and facilitates smooth paper output. If printer 1 is placed on a desktop in this manner, the depth direction z of the first receiving cavity 211 is approximately horizontal, and the first paper output port 2122 extends approximately horizontally, so that the width direction of the label paper 311 output from the first paper output port 2122 is approximately horizontal. Alternatively, if printer 1 is used on a desktop, the second end face 2f can be placed on the desktop, so that the first surface 2a is located to the side, and the first paper output port 2122 is located to the side. When the first paper output port 2122 outputs label paper 311, the label paper 311 is output towards the side of printer 1, and the side of printer 1 is unconstrained, which will not cause paper accumulation and facilitates smooth paper output. If printer 1 is placed on a desktop in this manner, the depth direction z of the first receiving cavity 211 is approximately vertical, and the first paper output port 2122 extends approximately vertically, so that the width direction of the label paper 311 output from the first paper output port 2122 is approximately vertical.

[0075] When holding the printer 1 by hand, the palm can support the second end face 2f while the fingers hold the first surface 2a and the fourth surface 2d, so that the first surface 2a is located to the side and the first paper output port 2122 is located to the side. When outputting label paper 311, the label paper 311 is output towards the side of the printer 1, and the side of the printer 1 is unconstrained, which will not cause paper accumulation and facilitates smooth paper output. If the printer 1 is held in this way, the depth direction z of the first receiving cavity 211 is approximately vertical, and the first paper output port 2122 extends approximately vertically, so that the width direction of the label paper 311 output from the first paper output port 2122 is approximately vertical.

[0076] The second surface 2b is closer to the first paper output port 2122 than the third surface 2c. That is, the distance between the first paper output port 2122 and the third surface 2c is greater than the distance between the first paper output port 2122 and the second surface 2b. Therefore, if the printer 1 is placed with the third surface 2c on a table, a larger paper output distance can be formed between the first paper output port 2122 and the third surface 2c, making it less likely that the label paper 311 output from the first paper output port 2122 will stick to the table, facilitating smooth paper output. If the printer 1 is held in the same way, a larger gripping area is provided between the first paper output port 2122 and the third surface 2c, making it less likely that holding the printer will affect the paper output from the paper output port 112. In some embodiments, the distance H1 from the first paper output port 2122 to the second surface 2b and the distance H2 from the first paper output port 2122 to the third surface 2c satisfy: 0.1 ≤ H1 / H2 ≤ 0.8. By reasonably limiting the ratio of the distance from the first paper outlet 2122 to the second surface 2b to the distance from the first paper outlet 2122 to the third surface 2c, it is beneficial to achieve a larger paper output distance or a larger gripping area between the first paper outlet 2122 and the third surface 2c, thus optimizing the structural layout of the printer 1. If H1 / H2 is less than 0.1, the distance from the first paper outlet 2122 to the second surface 2b will be too small, which is not conducive to the setting of components such as the rubber roller; if H1 / H2 is greater than 0.8, the distance from the first paper outlet 2122 to the third surface 2c will be too large, increasing the size of the printer 1. H1 / H2 can be 0.1, 0.3, 0.5, 0.8, etc. In some embodiments, the distance H2 from the first paper outlet 2122 to the third surface 2c satisfies: H2 ≥ 6 cm. By reasonably limiting the distance from the first paper outlet 2122 to the third surface 2c, it is beneficial to achieve a sufficient paper output distance or a sufficient gripping area between the first paper outlet 2122 and the third surface 2c. Here, H2 can be 6mm, 26mm, 46mm, 66mm, 86mm, etc.

[0077] It should be emphasized that the distance from the second surface 2b to the first paper outlet 2122 can also be equal to the distance from the third surface 2c to the first paper outlet 2122, and there is no limitation on this.

[0078] The inner wall of the first paper output channel 212 includes a paper output side guide surface 2123 adjacent to the first paper output port 2122. In a direction perpendicular to the first surface 2a and pointing from the first paper inlet 2121 to the first paper output port 2122, the paper output side guide surface 2123 extends at an angle relative to the third surface 2c, gradually approaching it. The paper output side guide surface 2123 can guide the label paper 311. Designed to extend at an angle relative to the third surface 2c, if the printer 1 is placed with the third surface 2c placed on a table, the paper output side guide surface 2123 can guide the label paper 311 towards the table, achieving downward tilting paper output and smoother paper output. If the printer 1 is placed on the table with the second end face 2f as described above, or if the printer 1 is held by hand in the manner described above, with the third surface 2c facing the user, the paper guide surface 2123 on the paper output side can tilt and guide the label paper 311 toward the direction closer to the user, so that the label paper 311 is tilted toward the user for paper output, making it easier for the user to touch the label paper 311.

[0079] The angle between the paper output guide surface 2123 and the third surface 2c is θ1, where θ1 satisfies: 30°≤θ1≤60°. By reasonably limiting the angle between the paper output guide surface 2123 and the third surface 2c, the bending angle of the label paper 311 guided by the paper output guide surface 2123 is appropriate, resulting in smoother paper output. If the angle between the paper output guide surface 2123 and the third surface 2c is less than 30°, the bending degree of the label paper 311 output through the paper output guide surface 2123 will be too large, resulting in poor guidance effect towards the desktop or user; if the angle between the paper output guide surface 2123 and the third surface 2c is greater than 60°, the bending degree of the label paper 311 when it is conveyed to the paper output guide surface 2123 will be too large, causing the paper output guide surface 2123 to fail to provide a guiding effect or to have a poor guiding effect. θ1 can be 30°, 40°, 45°, 50°, 60°, etc.

[0080] The length of the paper guide surface 2123 on the output side of the paper output channel 212 in the paper guiding direction is L1, where L1 satisfies: 5mm ≤ L1 ≤ 20mm. By reasonably limiting the length of the paper guide surface 2123 on the output side of the paper output channel 212 in the paper guiding direction, the guiding effect of the paper guide surface 2123 is appropriate, resulting in smoother paper output. If the length of the paper guide surface 2123 on the output side of the paper output channel 212 in the paper guiding direction is less than 5mm, the paper guide surface 2123 will not have a guiding effect or the guiding effect will be poor; if the length of the paper guide surface 2123 on the output side of the paper output channel 212 in the paper guiding direction is greater than 20mm, the volume of the printer 1 will increase. L1 can be 5mm, 10mm, 15mm, 20mm, etc.

[0081] The inner wall of the first paper output channel 212 includes a paper feed side guide surface 2124 adjacent to the first paper inlet 2121. In a direction perpendicular to the first surface 2a and pointing from the first paper inlet 2121 to the first paper output outlet 2122, the paper feed side guide surface 2124 extends in a direction parallel to the third surface 2c. After the label paper 311 is printed, it enters the first paper output channel 212 through the first paper inlet 2121. After being guided by the paper feed side guide surface 2124 and the paper output side guide surface 2123, it is output to the outside of the printer 1 through the first paper output outlet 2122. The design, with the paper feed side guide surface 2124 extending in a direction parallel to the third surface 2c in a direction perpendicular to the first surface 2a and pointing from the first paper inlet 2121 to the first paper output outlet 2122, facilitates the smooth transport of the printed label paper 311 within the first paper output channel 212.

[0082] The length of the paper feed side guide surface 2124 in the paper guide direction of the first paper output channel 212 is L2, where L2 satisfies: 10mm ≤ L2 ≤ 30mm. By reasonably limiting the length of the paper feed side guide surface 2124 in the paper guide direction of the first paper output channel 212, the guiding effect of the paper feed side guide surface 2124 is appropriate, and the paper output is smoother. If the length of the paper feed side guide surface 2124 in the paper guide direction of the first paper output channel 212 is less than 10mm, the label paper 311 will be easily bent at the paper feed side guide surface 2124; if the length of the paper feed side guide surface 2124 in the paper guide direction of the first paper output channel 212 is greater than 30mm, the volume of the printer 1 will increase. L2 can be 10mm, 15mm, 20mm, 25mm, 30mm, etc.

[0083] In a direction perpendicular to the first surface 2a and pointing from the first paper inlet 2121 to the first paper outlet 2122, the height of the first paper outlet channel 212 gradually decreases at the first paper inlet 2121. After printing, the label paper 311 enters the first paper outlet channel 212 through the first paper inlet 2121. The design of the gradually decreasing height of the first paper outlet channel 212 at the first paper inlet 2121 in a direction perpendicular to the first surface 2a and pointing from the first paper inlet 2121 to the first paper outlet 2122 facilitates the label paper 311 to pass through the larger channel height into the first paper outlet channel 212, preventing the label paper 311 from getting stuck on the side of the first paper inlet 2121 and being unable to enter the first paper outlet channel 212. Then, during the transmission process in the first paper outlet channel 212, the channel height decreases, allowing the first paper outlet channel 212 to play a guiding role.

[0084] The first paper output channel 212 has a first sidewall 2125 and a second sidewall 2126 opposite to each other in the width direction of the label paper 311. The label paper 311 has a first edge line 3111 and a second edge line 3112 opposite to each other in the width direction. When the first paper output channel 212 outputs the label paper 311, the first sidewall 2125 is adjacent to the first edge line 3111 and the second sidewall 2126 is adjacent to the second edge line 3112.

[0085] The distance between the first sidewall 2125 and the first edge line 3111 is R1, where R1 satisfies: 0.3mm ≤ R1 ≤ 1.5mm. By reasonably limiting the distance between the first sidewall 2125 and the first edge line 3111, paper can flow smoothly within the first paper output channel 212. If the distance between the first sidewall 2125 and the first edge line 3111 is less than 0.3mm, the label paper 311 may easily scrape against the first sidewall 2125 when outputting label paper, affecting paper feeding. If the distance between the first sidewall 2125 and the first edge line 3111 is greater than 1.5mm, the label paper 311 may easily wobble within the first paper output channel 212 when outputting label paper, affecting printing quality and increasing the size of the printer 1. R1 can be 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc.

[0086] The distance between the second sidewall 2126 and the second edge line 3112 is R2, where R2 satisfies: 0.3mm ≤ R2 ≤ 1.5mm. If the distance between the second sidewall 2126 and the second edge line 3112 is less than 0.3mm, the label paper 311 may easily scrape against the second sidewall 2126 when outputting the label paper 311 from the first paper output channel 212, affecting paper feeding. If the distance between the second sidewall 2126 and the second edge line 3112 is greater than 1.5mm, the label paper 311 may easily wobble within the first paper output channel 212 when outputting the label paper 311, affecting printing quality and increasing the size of the printer 1. R2 can be 0.3mm, 0.5mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, etc.

[0087] The printer body 2 includes a print head 23 and a rubber roller 24, which are located inside the printer body 2. Label paper 311 is sandwiched between the print head 23 and the rubber roller 24. The print head 23 is used to print on the label paper 311, and the rubber roller 24 is used to feed the label paper 311 into and out of the printer. The rubber roller 24 can move towards or away from the print head 23 to clamp or release the label paper 311.

[0088] The printhead 23 has a printing surface 23a and a back surface 23b facing away from each other. The printing surface 23a faces the second surface 2b and the back surface 23b faces the third surface 2c. The roller 24 is located between the printing surface 23a and the second surface 2b and is positioned corresponding to the printing surface 23a. If the printer 1 is placed on a table with the second end face 2f as described above, or if the printer 1 is held by hand in the manner described above, with the third surface 2c facing the user, then the printing surface 23a faces away from the user. This allows the label paper 311 printed through the printing surface 23a to be output through the first paper output port 2122, with the printed information on the label paper 311 facing the user, making it convenient for the user to view the printing effect. Furthermore, the second surface 2b is closer to the first paper output port 2122 than the third surface 2c. That is, the user is farther from the output label paper 311 when positioned on the third surface 2c side than when positioned on the second surface 2b side, ensuring sufficient distance between the user and the output label paper 311 for the user to clearly see the printed information on the label paper 311.

[0089] The printhead 23 has a print line 2311. The projection of the print line 2311 into a preset reference plane is located on the side of the paper feed port 111 of the paper output channel 11 that is closer to or farther from the second surface 2b, wherein the preset reference plane is parallel to the first surface 2a. That is, the print line 2311 and the paper feed port 111 of the paper output channel 11 have a height difference within the preset reference plane. To ensure that the printed label paper 311 can reach the paper inlet 111 of the paper output channel 11 under the conveying of the rubber roller 24, in this embodiment, the printing surface 23a is designed to be inclined relative to the second surface 2b in a first direction x perpendicular to the first surface 2a. Since the rubber roller 24 drives the label paper 311 to move through friction, after the label paper 311 is printed, it is output in a direction that is approximately away from the back surface 23b and inclined relative to the printing surface 23a under the action of the rubber roller 24. The design of the printing surface 23a being inclined relative to the second surface 2b in the first direction x perpendicular to the first surface 2a can adjust the tilt angle of the output direction of the label paper 311 relative to the second surface 2b, which is conducive to the label paper 311 crossing the height difference to reach the paper inlet 111 of the paper output channel 11, thus facilitating smooth paper output.

[0090] In the first direction x perpendicular to the first surface 2a, the angle between the printing surface 23a and the second surface 2b is α1, where α1 satisfies: -25°≤α1≤25°. If α1 is between -25° and 0°, along the first direction x and from the paper inlet 111 to the paper outlet 112, the printing surface 23a extends in a tendency to move away from the second surface 2b. In this case, the tilt angle of the label paper 311's output direction relative to the second surface 2b will be reasonably adjusted in a direction away from the second surface 2b, facilitating the label paper 311 to cross the height difference and reach the paper inlet 111 of the paper outlet channel 11. If α1 is between 0 and 25°, along the first direction x, from the paper inlet 111 to the paper outlet 112, the printing surface 23a extends in a tendency to move closer to the second surface 2b. In this case, the tilt angle of the label paper 311's output direction relative to the second surface 2b will be reasonably adjusted towards the second surface 2b, which is beneficial for the label paper 311 to cross the height difference and reach the paper inlet 111 of the paper outlet channel 11. If α1 is less than -25°, the adjustment of the tilt angle of the label paper 311's output direction relative to the second surface 2b will be too large, which will reduce the smoothness of paper output; if α1 is greater than 25°, the adjustment of the tilt angle of the label paper 311's output direction relative to the second surface 2b will be too large, which will reduce the smoothness of paper output. Specifically, if the projection of the printing line 2311 onto the preset reference surface is located on the side of the paper inlet 111 of the paper output channel 11 that is far from the second surface 2b, and if α1 is less than -25°, the tilt angle of the label paper 311 relative to the second surface 2b will be adjusted too much in the direction away from the second surface 2b, making it more difficult for the label paper 311 to reach the paper inlet 111 of the paper output channel 11, thus reducing the smoothness of paper output; if α1 is greater than 25°, the tilt angle of the label paper 311 relative to the second surface 2b will be adjusted too much in the direction closer to the second surface 2b, and if the paper inlet 111 of the paper output channel 11 extends approximately along the first direction x, the bending angle of the label paper 311 when entering the paper inlet 111 will increase, thus reducing the smoothness of paper output. Here, α1 can be -25°, -15°, -5°, 5°, 15°, 25°, etc.

[0091] If, along the first direction x, from the paper inlet 111 to the paper outlet 112, the printing surface 23a extends at an angle relative to the second surface 2b, and the projection of the printing surface 23a onto the preset reference plane is located on the side of the projection of the paper inlet 111 onto the preset reference plane that is away from the second surface 2b. That is, the projection of the entire printing surface 23a onto the preset reference plane is located on the same side as the projection of the paper inlet 111 onto the preset reference plane, and the edge of the printing surface 23a closest to the paper inlet 111 is the edge of the printing surface 23a closest to the second surface 2b. In this way, the output direction of the label paper 311 will be adjusted towards the direction closer to the paper outlet 112, which is beneficial for the label paper 311 to cross the height difference and reach the paper inlet 111 of the paper outlet channel 11.

[0092] See Figure 4 The distance between the printing line 2311 and the paper feed tray 111 in the first direction x is M1, where M1 satisfies: 5mm ≤ M1 ≤ 10mm. By reasonably limiting the distance between the printing line 2311 and the paper feed tray 111 in the first direction x, paper output becomes smoother. If the distance between the printing line 2311 and the paper feed tray 111 in the first direction x is less than 5mm, the label paper 311 will be bent too much, resulting in poor paper output smoothness; if the distance between the printing line 2311 and the paper feed tray 111 in the first direction x is greater than 10mm, the size of the printer 1 will increase. M1 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc.

[0093] See Figure 4 The distance between the printing line 2311 and the paper feed port 111 in the second direction y is M2, where M2 satisfies: 0.5mm ≤ M2 ≤ 5mm; the second direction y is parallel to the first surface 2a and along the distribution direction of the printing surface 23a and the back surface 23b. By reasonably limiting the distance between the printing line 2311 and the paper feed port 111 in the second direction y, paper output is smoother and easier to install the consumable box 3. If the distance between the printing line 2311 and the paper feed port 111 in the second direction y is less than 0.5mm, the label paper 311 and the ribbon 321 may easily scratch the print head 23 when the consumable box 3 is inserted into the printer body 2, making it difficult to install the consumable box 3; if the distance between the printing line 2311 and the paper feed port 111 in the second direction y is greater than 5mm, the bending degree of the label paper 311 will be too large, and the smoothness of paper output will be worse. M2 can be 0.5mm, 1mm, 2mm, 3mm, 4mm, 5mm, etc.

[0094] Due to structural and technological requirements, the printing surface 23a may have raised portions 2312. To avoid interference between the raised portions 2312 on the printing surface 23a and the consumable paper, combined with... Figure 7During printing, the consumable paper is separated from the raised portion 2312. For example, the print head 23 is provided with epoxy resin that protects the internal components and makes the printing surface 23a smooth. The printing surface 23a forms a raised portion 2312 in the part corresponding to the epoxy resin. When the roller 24 presses against the print head 23 to print, the consumable paper is separated from the raised portion 2312, which can prevent the ribbon 321 from scratching the raised portion 2312 and falling off.

[0095] See Figure 7 During printing, the distance between the consumable paper and the raised portion 2312 in the second direction y is S2, where S2 satisfies: 0.5mm ≤ S2 ≤ 2mm. By reasonably limiting the distance between the consumable paper and the raised portion 2312 in the second direction y during printing, it is possible to avoid the ribbon 321 scraping against the raised portion 2312 and to achieve a suitable size for the printer 1. If the distance between the consumable paper and the raised portion 2312 in the second direction y is less than 0.5mm, there is still a risk that the ribbon 321 will scrape against the raised portion 2312; if the distance between the consumable paper and the raised portion 2312 in the second direction y is greater than 2mm, the size of the printer 1 will increase. S2 can be 0.5mm, 1mm, 1.5mm, 2mm, etc.

[0096] See Figure 5 The printhead 23 includes a print patch 231, which has opposing print surfaces 23a and a first surface 2313. The first surface 2313 is approximately parallel to the print surface 23a. This results in a relatively uniform thickness for the print patch 231. If the print surface 23a is tilted relative to the second surface 2b, then the entire print patch 231 is tilted relative to the second surface 2b. This allows for adjustment of the mounting orientation of the print patch 231 to achieve the tilt of the print surface 23a relative to the second surface 2b.

[0097] See Figure 5 The printhead 23 includes a print substrate 232, which has a second side 2321 and a back side 23b facing away from each other. A first side 2313 of a print patch 231 is attached to the second side 2321 of the print substrate 232. The back side 23b is parallel to the print surface 23a. Thus, the overall thickness of the print patch 231 and the print substrate 232 is approximately uniform. If the print surface 23a is tilted relative to the second surface 2b, then the print patch 231 and the print substrate 232 are tilted relative to the second surface 2b. In this way, the overall mounting orientation of the print patch 231 and the print substrate 232 can be adjusted to achieve the tilt of the print surface 23a relative to the second surface 2b.

[0098] See Figure 5The printhead 23 includes a paper stop strip 233, which is connected to and protrudes from the second surface 2321 of the print substrate 232. The paper stop strip 233 is located on the side of the print patch 231 near the paper inlet 111 of the paper output channel 11. The paper stop strip 233 protrudes from the print patch 231, thus preventing the consumable paper from being scraped off by the edge of the print patch 231 when it is returned, which would cause a paper jam.

[0099] See Figure 5 The protrusion height of the paper stop strip 233 relative to the printing patch 231 is N1, where N1 satisfies the condition: 0.02mm ≤ N1 ≤ 0.1mm. By reasonably limiting the protrusion height of the paper stop strip 233 relative to the printing patch 231, both smooth paper output and paper jam prevention can be achieved. If the protrusion height of the paper stop strip 233 relative to the printing patch 231 is less than 0.02mm, the paper stop strip 233 cannot prevent paper jams; if the protrusion height of the paper stop strip 233 relative to the printing patch 231 is greater than 0.1mm, it will increase the bending angle of the consumable paper when it moves towards the paper inlet 111 of the paper output channel 11 after printing, thus causing uneven paper output. N1 can be 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, etc.

[0100] See Figure 5 The distance between the paper stop strip 233 and the printing line 2311 in the first direction x is N2, where N2 satisfies: 1.2mm ≤ N2 ≤ 2.5mm. By reasonably limiting the distance between the paper stop strip 233 and the printing line 2311 in the first direction x, both clear printing and a suitable size for the printer 1 can be achieved. If the distance between the paper stop strip 233 and the printing line 2311 in the first direction x is less than 1.2mm, the paper stop strip 233 is prone to pressing against the rubber roller 24, causing the rubber roller 24 to fail to press the consumable paper firmly, resulting in unclear printing; if the distance between the paper stop strip 233 and the printing line 2311 in the first direction x is greater than 2.5mm, the size of the printer 1 will increase. N2 can be 1.2mm, 1.5mm, 2.0mm, 2.3mm, 2.5mm, etc.

[0101] See Figure 5 The rubber roller 24 has a pressing surface 241 arranged around the first axis. The rubber roller 24 can rotate around the first axis, and the printing line 2311 is parallel to the first axis to ensure that the clamping force of the rubber roller 24 and the print head 23 on the consumable paper is consistent, so that the printing is clear.

[0102] The projection of the printing line 2311 in the second reference surface is located inside the projection of the pressing surface 241 in the second reference surface, and the second reference surface is parallel to the first axis. In this way, when the rubber roller 24 clamps the consumable paper between the print head 23, the rubber roller 24 can cover the entire printing line 2311, preventing the user from directly touching the heating line and getting burned.

[0103] See Figure 11 The printer body 2 includes a cutting assembly 25 having a cutting position in which at least a portion of the cutting assembly 25 is located in a first paper output channel 212, enabling it to cut label paper 311 within the first paper output channel 212. A second receiving cavity 213 is formed within the printer body 2 to accommodate at least a portion of the cutting assembly 25, and the second receiving cavity 213 communicates with the first paper output channel 212. In some embodiments, the second receiving cavity 213 is formed between the inner wall of the first receiving cavity 211 and a first surface 2a. In other embodiments, the second receiving cavity 213 is formed between the inner wall of the first receiving cavity 211 and a second surface 2b.

[0104] See Figure 11 The cutting assembly 25 includes a first cutting section 251. In the cutting position, the cutting edge of the first cutting section 251 is located inside the first paper output channel 212, so as to be able to cut the label paper 311 inside the first paper output channel 212. The cutting assembly 25 also has a waiting position, in which the cutting edge of the first cutting section 251 is located outside the first paper output channel 212, so that the label paper 311 can pass smoothly through the first paper output channel 212.

[0105] See Figure 11 The cutting assembly 25 includes a second cutting portion 252. The extending direction of the first cutting portion 251 and the extending direction of the second cutting portion 252 are set at an angle. The cutting assembly 25 is configured such that the first cutting portion 251 and the second cutting portion 252 can rotate relative to each other, reducing the angle between the first cutting portion 251 and the second cutting portion 252, so that the cutting assembly 25 is in the cutting position. That is, when the cutting assembly 25 cuts the label paper 311, the first cutting portion 251 and the second cutting portion 252 cut at an angle, which is beneficial for the label paper 311 to be cut neatly.

[0106] The first cutting part 251 and the second cutting part 252 can rotate relative to each other. Both the first cutting part 251 and the second cutting part 252 can move relative to the first paper output channel 212, or the first cutting part 251 can move relative to the first paper output channel 212 while the second cutting part 252 is fixed relative to the first paper output channel 212.

[0107] In this embodiment, the second cutting part 252 is disposed corresponding to and fixed relative to the first paper output channel 212. The second cutting part 252 extends along the depth direction z of the first receiving cavity 211. When the cutting assembly 25 switches from the waiting position to the cutting position, the first cutting part 251 moves relative to the first paper output channel 212 to approach the second cutting part 252, and together with the second cutting part 252, completes the cutting of the label paper 311. The movement of the first cutting part 251 relative to the first paper output channel 212 can be a rotation of the first cutting part 251 relative to the second cutting part 252, thereby reducing the angle between the first cutting part 251 and the second cutting part 252, achieving angled cutting of the label paper 311.

[0108] See Figure 11 The cutting assembly 25 includes a rotating shaft 253, and a first cutting part 251 is sleeved on the rotating shaft 253. When the cutting assembly 25 switches from the waiting position to the cutting position, the first cutting part 251 rotates around the central axis of the rotating shaft 253, reducing the included angle between the first cutting part 251 and the second cutting part 252, thereby achieving angled cutting of the label paper 311. The second cutting part 252 may also be sleeved on the rotating shaft 253; this is not a limitation.

[0109] See Figure 11 The cutting assembly 25 includes a pressing part 254 connected to the first cutting part 251. The printer body 2 includes a button 26, the pressing surface 261 of which is exposed on the surface of the printer body 2. The pressing part 254 is located in the pressing direction of the button 26. The button 26 is configured to act on the pressing part 254 when pressed, thereby switching the first cutting part 251 from the waiting position to the cutting position. Thus, the user can directly operate the button 26 from outside the printer body 2 to switch the first cutting part 251 from the waiting position to the cutting position, which is convenient.

[0110] See Figure 9 The button 26 is located between the first paper output port 2122 and the third surface 2c, and the pressing surface 261 of the button 26 is exposed through the first end face 2e. Thus, when the printer 1 is held in the above manner, the button 26 is located in the holding area, which makes it convenient for the user to touch and press the button 26 during the holding process.

[0111] See Figure 9 The printer body 2 has a button groove 214, and at least a portion of the button 26 is located within the button groove 214, which extends through the first surface 2a. This reduces the constraint of the first surface 2a on the button 26, making it easier to press the button 26 when holding the printer 1 in the aforementioned manner.

[0112] See Figure 8The printer body 2 includes a housing 27 and a cover 28. The housing 27 and the cover 28 are closed together in the depth direction z of the first receiving cavity 211. The first receiving cavity 211 and the first paper output channel 212 are formed between the cover 28 and the housing 27. The housing 27 and the cover 28 are movably connected. Thus, when the housing 27 and the cover 28 move relative to each other to open the first receiving cavity 211, it is convenient to put and take the consumables box 3 on the printer body 2.

[0113] The movable connection between the box body 27 and the cover body 28 can be a rotatable connection, allowing the box body 27 and the cover body 28 to rotate relative to each other to open the first receiving cavity 211, while maintaining the connection between the box body 27 and the cover body 28 when the first receiving cavity 211 is opened, without the need for disassembly and reassembly. The box body 27 and the cover body 28 can be rotatably connected on the side where the fourth surface 2d is located, so that when the box body 27 and the cover body 28 rotate relative to each other to open the first receiving cavity 211, the opened cover body 28 is located on the side where the fourth surface 2d is located, away from the first paper outlet 2122, and is less likely to obstruct the assembly of the label paper 311 in the first paper outlet channel 212.

[0114] The cover 28 covers the print head 23. When the cover 28 is closed with the box 27, it covers the print head 23, which can prevent the user from being burned by the print head 23 during use.

[0115] Viewed from the side of the cover 28 away from the box 27, the cover 28 covers the first paper output channel 212. When the cover 28 is closed with the box 27, it covers the first paper output channel 212, which can prevent the user from reaching into the first paper output channel 212 from the side of the cover 28 and avoid being cut by the cutting component 25 in the first paper output channel 212.

[0116] See Figure 12 The printer body 2 includes a mechanism support 29, which is connected to the printing substrate 232 of the printhead 23. The printhead 23 generates heat during printing; connecting it to the mechanism support 29 increases the heat dissipation area, facilitating heat dissipation. Both the mechanism support 29 and the printing substrate 232 can be made of metal, which has better thermal conductivity, further accelerating heat dissipation. The thickness of the printing substrate 232 in the direction perpendicular to the printing surface 23a is T1, where T1 satisfies: 3mm ≤ T1 ≤ 8mm. By reasonably limiting the thickness of the printing substrate 232 in the direction perpendicular to the printing surface 23a, both good heat dissipation and a suitable printer size can be achieved. If the thickness of the printing substrate 232 in the direction perpendicular to the printing surface 23a is less than 3mm, the thickness of the printing substrate 232 will be too small, which is not conducive to heat dissipation; if the thickness of the printing substrate 232 in the direction perpendicular to the printing surface 23a is greater than 8mm, the thickness of the printing substrate 232 will be too large, increasing the size of the printer 1. T1 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc. See also... Figure 10The length of the printing substrate 232 in the third preset direction is T2, where T2 satisfies: 10mm ≤ T2 ≤ 25mm. The third preset direction is parallel to the printing surface 23a and follows the distribution direction of the first side surface 23c and the second side surface 23d of the print head 23. By reasonably limiting the length of the printing substrate 232, both good heat dissipation and a suitable size for the printer 1 can be achieved. If the length of the printing substrate 232 is less than 10mm, it will be too small, which is not conducive to heat dissipation; if the length of the printing substrate 232 is greater than 25mm, it will be too large, increasing the size of the printer 1. T2 can be 10mm, 15mm, 20mm, 25mm, etc.

[0117] See Figure 12 The mechanism support 29 and the printing substrate 232 can be integrally molded. Compared with separate molding and assembly, this reduces the assembly process and makes the heat transfer between the two faster and more efficient, preventing the temperature of the print head 23 from getting too high and further avoiding the risk of users being accidentally burned.

[0118] See Figure 12 The printer body 2 has a receiving section 215 for accommodating the mechanism support 29. The receiving section 215 is located at the bottom of the first receiving cavity 211, that is, the receiving section 215 is formed between the inner bottom wall 2111 of the first receiving cavity 211 and the second end face 2f. The printing substrate 232 passes through the inner bottom wall 2111 of the first receiving cavity 211. The receiving section 215 can communicate with the second receiving cavity 213.

[0119] Next, see Figures 1 to 12 Detailed explanation of consumable box 3.

[0120] See Figure 1 The consumable cartridge 3 is located within the first receiving cavity 211 of the printer body 2, and the spool of the ribbon roll 32 of the consumable cartridge 3 is sleeved on the drive shaft 22 within the first receiving cavity 211. The printer body 2 can drive the drive shaft 22 to rotate around its central axis, thereby driving the spool of the ribbon roll 32 to rotate around the central axis of the drive shaft 22, thus driving the ribbon 321 to rotate.

[0121] See Figure 1The consumable cartridge 3 has a second top surface 3a that faces away from the inner bottom wall 2111 of the first receiving cavity 211, and the print head 23 has a first top surface 23e that faces away from the inner bottom wall 2111. Along the depth direction z of the first receiving cavity 211, the first top surface 23e is flush with the second top surface 3a or located between the second top surface 3a and the inner bottom wall 2111. The first top surface 23e being flush with the second top surface 3a can mean that they are coplanar. Therefore, having the first top surface 23e flush with the second top surface 3a or located between the second top surface 3a and the inner bottom wall 2111 ensures that after the consumable cartridge 3 is placed into the first receiving cavity 211 of the printer body 2, the first top surface 23e of the print head 23 does not protrude from the second top surface 3a of the consumable cartridge 3, reducing the risk of burns caused by the user touching the print head 23.

[0122] Along the depth direction z of the first receiving cavity 211, the distance between the first top surface 23e and the second top surface 3a is F1, where F1 satisfies: 0 ≤ F1 ≤ 5 mm. By reasonably limiting the distance between the first top surface 23e and the second top surface 3a along the depth direction z of the first receiving cavity 211, the effects of preventing user burns and ensuring a suitable volume for the consumable box 3 can be achieved. If the distance between the first top surface 23e and the second top surface 3a along the depth direction z of the first receiving cavity 211 is greater than 5 mm, the height of the print head 23 along the depth direction z of the first receiving cavity 211 needs to be increased, thus increasing the volume of the consumable box 3. Here, F1 can be 0, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0123] To further prevent users from being burned by the printhead 23, the consumable cartridge 3, after being placed into the first receiving cavity 211 of the printer body 2, can partially surround the printhead 23. In some embodiments, see [reference]. Figure 5 The print head 23 has a printing surface 23a, a second side surface 23d, a back surface 23b, and a first side surface 23c distributed around a first preset direction, the first preset direction being along the depth direction z of the first receiving cavity 211. The printing surface 23a, the second side surface 23d, the back surface 23b, and the first side surface 23c can be connected sequentially. At least a portion of the first side surface 23c, at least a portion of the second side surface 23d, and the back surface 23b are surrounded by a consumable cartridge 3, which forms an opening 301 at the printing surface 23a. The rubber roller 24 can move from the opening 301 towards the printing surface 23a to hold the label paper 311 with the printing surface 23a.

[0124] The consumable cartridge 3 has a first surrounding surface 302 corresponding to the back surface 23b. The distance between the first surrounding surface 302 and the back surface 23b is F2, which satisfies the condition: 1mm ≤ F2 ≤ 3.5mm. By reasonably limiting the distance between the first surrounding surface 302 and the back surface 23b, the performance of the ribbon 321 and the safety of the printer 1 can be improved simultaneously. If the distance between the first surrounding surface 302 and the back surface 23b is less than 1mm, the distance between the print head 23 and the consumable cartridge 3 will be too small, and the heat generated by the print head 23 during operation will easily affect the ribbon 321. In particular, the ribbon 321 is prone to failure when exposed to high temperatures for a long time. If the distance between the first surrounding surface 302 and the back surface 23b is greater than 3.5mm, the distance between the print head 23 and the consumable cartridge 3 will be too large, increasing the risk of burns caused by users accidentally placing their hands between the print head 23 and the consumable cartridge 3. F2 can be 1mm, 2mm, 3mm, 3.5mm, etc. F2 can be the distance between the first enclosing surface 302 and the back surface 23b in the second direction y.

[0125] The consumable cartridge 3 has a second surrounding surface 303 corresponding to the second side 23d. The distance between the second surrounding surface 303 and the second side 23d is F3, which satisfies the condition: 1mm ≤ F3 ≤ 3.5mm. By reasonably limiting the distance between the second surrounding surface 303 and the second side 23d, both the performance of the ribbon 321 and the safety of the printer 1 can be improved. If the distance between the second surrounding surface 303 and the second side 23d is less than 1mm, the distance between the print head 23 and the consumable cartridge 3 will be too small, and the heat generated by the print head 23 during operation will easily affect the ribbon 321. In particular, the ribbon 321 is prone to failure when exposed to high temperatures for a long time. If the distance between the second surrounding surface 303 and the second side 23d is greater than 3.5mm, the distance between the print head 23 and the consumable cartridge 3 will be too large, increasing the risk of burns caused by users accidentally placing their hands between the print head 23 and the consumable cartridge 3. F3 can be 1mm, 2mm, 3mm, 3.5mm, etc. F3 can be the distance between the second enclosing surface 303 and the second side surface 23d in the first direction x.

[0126] The consumable cartridge 3 has a third surrounding surface 304 corresponding to the first side 23c. The distance between the third surrounding surface 304 and the first side 23c is F4, which satisfies the condition: 1mm ≤ F4 ≤ 3.5mm. By reasonably limiting the distance between the third surrounding surface 304 and the first side 23c, both the performance of the ribbon 321 and the safety of the printer 1 can be improved. If the distance between the third surrounding surface 304 and the first side 23c is less than 1mm, the distance between the print head 23 and the consumable cartridge 3 will be too small, and the heat generated by the print head 23 during operation will easily affect the ribbon 321. In particular, the ribbon 321 is prone to failure when exposed to high temperatures for a long time. If the distance between the third surrounding surface 304 and the first side 23c is greater than 3.5mm, the distance between the print head 23 and the consumable cartridge 3 will be too large, increasing the risk of burns caused by users accidentally placing their hands between the print head 23 and the consumable cartridge 3. F4 can be 1mm, 2mm, 3mm, 3.5mm, etc. F4 can be the distance between the third enclosing surface 304 and the first side surface 23c in the first direction x.

[0127] The portion of the printing surface 23a near the second side 23d is surrounded by the consumable cartridge 3. And / or, the portion of the printing surface 23a near the first side 23c is surrounded by the consumable cartridge 3. That is, the edge of the printing surface 23a is surrounded by the consumable cartridge 3, thus reducing the length of the opening 301 and decreasing the risk of burns caused by the user accidentally putting their hand into the opening 301.

[0128] If the second side 23d is closer to the print line 2311 than the first side 23c, the portion of the print surface 23a closest to the first side 23c is surrounded by the consumable box 3, and the consumable box 3 forms an opening 301 on the print surface 23a furthest from the first side 23c. That is, the side of the print surface 23a furthest from the print line 2311 is surrounded by the consumable box 3, while other parts are not surrounded. This allows the rubber roller 24 to easily pass through the opening 301 and act on the print line 2311 while reducing the length of the opening 301 to minimize the risk of burns to the user. The second side 23d is closer to the first paper output channel 212 than the first side 23c. That is, the print head 23 is surrounded by the consumable box 3 on the side furthest from the first paper output channel 212, while an opening 301 is formed on the side closest to the first paper output channel 212, facilitating smooth paper output. The second surrounding surface 303 has a first edge line 3031 away from the first surrounding surface 302 and a second edge line 3032 close to the first surrounding surface 302. The projection of the printing surface 23a into the first reference surface is located on the side where the projection of the first edge line 3031 into the first reference surface is close to the projection of the second edge line 3032 into the first reference surface. The first reference surface is parallel to the depth direction z of the first receiving cavity 211 and perpendicular to the distribution direction of the first side surface 23c and the second side surface 23d. That is, the first edge line 3031 is closer to the second surface 2b than the printing surface 23a, and the first reference surface is parallel to the first surface 2a. Thus, the printing surface 23a does not protrude from the first edge line 3031, which can better hide the print head 23 and prevent it from getting hot.

[0129] The consumable cartridge 3 has a fourth surrounding surface 305 corresponding to the printing surface 23a. The distance between the fourth surrounding surface 305 and the printing surface 23a is F5, which satisfies the condition: 1mm ≤ F5 ≤ 4mm. The ribbon 321 can be led out from the part of the consumable cartridge 3 that forms the fourth surrounding surface 305 and is located at the opening 301, which facilitates the clamping of the roller 24 and the print head 23. By reasonably limiting the distance between the fourth surrounding surface 305 and the printing surface 23a, the transfer effect of the ribbon 321 and the safety performance of the printer 1 can be improved simultaneously. If the distance between the fourth surrounding surface 305 and the printing surface 23a is less than 1mm, the ribbon 321 at the opening 301 will easily rub against the print head 23, affecting the transfer effect of the ribbon 321. If the distance between the fourth surrounding surface 305 and the printing surface 23a is greater than 4mm, the distance between the print head 23 and the consumable cartridge 3 will be too large, increasing the risk of burns caused by the user accidentally putting their hand between the print head 23 and the consumable cartridge 3. F5 can be 1mm, 2mm, 3mm, 4mm, etc. F5 can be the distance between the fourth enclosing surface 305 and the printed surface 23a in the second direction y.

[0130] The length of the opening 301 in the second preset direction is P1, where P1 satisfies: 10mm ≤ P1 ≤ 15mm. The second preset direction is perpendicular to the depth direction z of the first receiving cavity 211 and along the distribution direction of the first side surface 23c and the second side surface 23d. By reasonably limiting the length of the opening 301, the effects of ensuring the smooth passage of the rubber roller 24 to jointly hold the label paper 311 with the printing surface 23a and improving the safety performance of the printer 1 can be achieved. If the length of the opening 301 is less than 10mm, it is not conducive to the rubber roller 24 passing through the opening 301 to jointly hold the label paper 311 with the printing surface 23a. If the length of the opening 301 is greater than 15mm, it is easy for the user to accidentally touch the print head 23 and be burned by the print head 23. Among them, P1 can be 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. The second preset direction can be approximately along the first direction x.

[0131] See Figure 4 The consumable cartridge 3 is provided with a second paper output channel 331. In a direction perpendicular to the first surface 2a, the second paper output channel 331 is located between the print head 23 and the first paper output channel 212. The side of the second paper output channel 331 away from the first paper output channel 212 forms a paper inlet 111, and the side of the first paper output channel 212 away from the second paper output channel 331 forms a paper outlet 112. After the label paper 311 is printed, it is sequentially transported to the outside of the printer 1 through the second paper output channel 331 and the first paper output channel 212.

[0132] See Figure 5 The consumable cartridge 3 includes a paper output section 33, which forms a second paper output channel 331. The distance between the side of the paper baffle 233 away from the printing line 2311 and the paper output section 33 in the first direction x is S1, where S1 satisfies: 1.5mm ≤ S1 ≤ 3mm. By reasonably limiting the distance between the side of the paper baffle 233 away from the printing line 2311 and the paper output section 33, the effects of facilitating the placement of the consumable cartridge 3 into the printer body 2 and maintaining a suitable size for the printer 1 can be achieved. If the distance between the side of the paper baffle 233 away from the printing line 2311 and the paper output section 33 is less than 1.5mm, it is not convenient for the consumable cartridge 3 to be placed into the first receiving cavity 211 of the printer body 2. If the distance between the side of the paper baffle 233 away from the printing line 2311 and the paper output section 33 is greater than 3mm, it will increase the size of the printer 1. S1 can be 1.5mm, 2mm, 2.5mm, 3mm, etc.

[0133] See Figure 5 The paper output section 33 forms a second surrounding surface 303 on the surface adjacent to the print head 23. That is, the paper output section 33 protrudes from the print head 23. The distance between the printed line 2311 and the paper output section 33 in the first direction x can be the distance between the printed line 2311 and the second surrounding surface 303 in the first direction x.

[0134] See Figure 4 The angle between the paper output direction of the second paper output channel 331 and the paper input direction of the first paper output channel 212 is β1, where β1 satisfies: 175°≤β1≤185°. Specifically, if β1 is between 175° and 180°, along the first direction x from the paper input port 111 to the paper output port 112, the paper input direction of the first paper output channel 212 extends inclined towards the second surface 2b. If β1 is between 180° and 185°, along the first direction x from the paper input port 111 to the paper output port 112, the paper input direction of the first paper output channel 212 extends inclined away from the second surface 2b. By reasonably limiting the angle between the paper output direction of the second paper output channel 331 and the paper input direction of the first paper output channel 212, the label paper 311 can enter the first paper output channel 212 more smoothly from the second paper output channel 331. If β1 is less than 175° or greater than 185°, the bending angle of the label paper 311 when it enters the first paper output channel 212 from the second paper output channel 331 will be too large, which is not conducive to smooth paper feeding. Among them, β1 can be 175°, 178°, 180°, 183°, 185°, etc.

[0135] See Figure 4 In the direction perpendicular to the first surface 2a, the distance between the second paper output channel 331 and the first paper output channel 212 is Q1, where Q1 satisfies: 0.2mm ≤ Q1 ≤ 2mm. By reasonably limiting the distance between the second paper output channel 331 and the first paper output channel 212, both the ease of placing the consumable box 3 into the printer body 2 and the smooth paper feeding can be achieved. If the distance between the second paper output channel 331 and the first paper output channel 212 is less than 0.2mm, it is not conducive to placing the consumable box 3 into the first receiving cavity 211 of the printer body 2. If the distance between the second paper output channel 331 and the first paper output channel 212 is greater than 2mm, the label paper 311 may easily get stuck in the gap between the consumable box 3 and the printer body 2, affecting the paper feeding of the label paper 311. Among them, Q1 can be 0.2mm, 0.5mm, 0.8mm, 1.2mm, 1.5mm, 1.8mm, 2mm, etc.
