Problems solved by technology

[0005] The main problem to be solved is that the existing printer needs to waste the first printing paper in order to print the initial position accurately, and the edge of the printing paper needs to be flush with the paper outlet, which sometimes causes each printing paper to have a small section. leave blank, waste

Embodiment 1

[0039] Please refer to figure 1 , a printer for saving printing paper, comprising a base 10 on which an openable cover 14 is arranged. The front end of the machine base 10 is provided with a paper outlet 13, the rear end of the machine base 10 is provided with a paper inlet 11, and a paper passage 12 is arranged between the paper outlet 13 and the paper inlet 11. . A rubber roller 60 is arranged on the machine base 10 , and the rubber roller 60 is arranged on a side close to the paper outlet 13 . An openable and closable printer on-core module 20 is provided inside the machine base 10 . The printer on-core module 20 has a thermal sheet 21 located above the rubber roller 60 . The rubber roller 60 cooperates with the thermal sheet 21 for printing and imaging. In addition, the rubber roller 60 also has the function of absorbing paper, that is, driving the movement of the printing paper.

[0040] Please refer to figure 1 , including a seam mark detection unit 40, an edge dete...

Embodiment 2

[0045]Using the above-mentioned printer, especially when only the edge detection unit 50 is set and the seam mark detection unit 40 is not set, specifically include the following steps:

[0046] S1, set the printing paper;

[0047] S2, the edge detection unit 50 detects whether there is printing paper;

[0048] S3, if the printing paper is not detected in step 2, then control the printing paper to advance, when the edge detection unit 50 detects the edge of the printing paper, control the printing paper to stop moving; if step 2 detects the printing paper, then control the printing The paper moves backwards or forwards and backwards multiple times, and when the edge detection unit 50 detects the edge of the printing paper, it controls the printing paper to stop moving.

[0049] S4, controlling the edge of the printing paper to move to the initial printing position.

[0050] Therefore, only one edge detection unit 50 is needed to realize no waste of the first sheet of printin...

Embodiment 3

[0052] Please refer to figure 1 and figure 2 , using the above-mentioned printer, when the edge of the printing paper is located at the front end of the edge detection unit 50, such as when the printer core module 20 is loaded with paper after a paper jam, the edge of the printing paper protrudes from the outlet paper.

[0053] Specifically include the following steps:

[0054] S1, set the printing paper;

[0055] S2, when the seam mark detection unit 40 detects the paper and the edge detection unit 50 also detects the paper, then it is determined that the edge of the printing paper is located at the front end of the edge detection unit 50;

[0056] S3, controlling the printing paper to advance and retreat multiple times, the seam mark detection unit 40 detects one of the seam marks, and sends the seam mark position signal to the controller (not shown in the figure);

[0057] S4, the edge detection unit 50 detects whether there is paper above, and if paper is detected, the...

Abstract

A printer capable of saving printing paper comprises a machine base, a mark seaming detection unit, an edge detection unit and a controller. The mark seaming detection unit and the edge detection unit are connected with the controller separately; a rubber roller is arranged on the machine base and arranged on one side close to a paper outlet; the edge detection unit is arranged between the paper outlet and the rubber roller; and the mark seaming detection unit is arranged between the rubber roller and a paper inlet. According to a control method of the printer, firstly the edge detection unit and the mark seaming detection unit detect together to determine the initial state of the printing paper; and then according to the different states of the printing paper, the printing paper is controlled to advance or retreat, so that the edge detection unit detects the edge of the printing paper, and the mark seaming detection unit detects the height of the printing paper. No matter where the edge of the initial state of the printing paper is located, the first piece of printing paper can be not wasted, and the printing paper is saved.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a paper-saving printer and a control method thereof. Background technique [0002] A printer is one of the output devices of a computer, which is used to print computer processing results on related media. In recent years, the development of printers is getting faster and faster, and the fields of application are also very wide. For example, automatic teller machines in banks, cash registers in supermarkets and e-commerce delivery offices can be seen everywhere, used to print transaction receipts, receipts or express delivery Single wait. [0003] Among them, the printing paper needs to be replaced when it is used up. After the replacement, it is necessary to detect the edge of the paper in order to be able to print on it accurately, and because the existing paper feeding function and printing function are all carried out by rubber rollers. Realized that in order to detect the...
