Thermal barcode printer and printing method thereof

Abstract

The invention provides a thermal-sensitive barcode printer and a printing method thereof. The printer comprises a machine base and a printing head mounted on the machine base, wherein a paper passing channel is formed between the machine base and the printing head; a rubber roller is arranged at one side, close to the printing head, of the machine base; the printing head is provided with a thermal-sensitive sheet above the rubber roller; the printer further comprises a paper detection device and a paper feeding device which are arranged on the paper passing channel; the paper detection device comprises a first detection unit and a second detection unit; the first detection unit can be slidingly arranged on the machine base along the axial direction of the rubber roller; the first detection unit is arranged between the rubber roller and the paper feeding device; the rubber roller is arranged between the first detection unit and the second detection unit. The invention further provides the printing method used by the thermal-sensitive barcode printer. The two detection units are arranged at different positions of the paper passing channel respectively; after different states of paper sheets are detected, the paper is fed into the rubber roller and the thermal-sensitive sheet for printing, so that a first piece or first section of printing paper is not wasted and the waste of the printing paper is effectively reduced.

Description

technical field [0001] The invention relates to the printing field, in particular to a thermal barcode printer and a printing method of the thermal barcode printer. Background technique [0002] ATMs in banks, checkout counters in supermarkets, and e-commerce delivery offices are all equipped with thermal printers for printing transaction receipts, receipts or express delivery orders. With the development of e-commerce, the business volume of express delivery is also growing at a high speed. In the past, the express delivery form was filled out by hand, and then the thermal printer can be used to print the font on the corresponding position of the express delivery form, thereby effectively improving the efficiency of express delivery. . [0003] Thermal printers typically have a housing within which the movement is mounted. The core includes print head, rubber roller and paper cutter, etc. When using a receipt printer, it is usually necessary to place a courier or printin...

Problems solved by technology

[0004] However, printing paper such as courier bills needs to be replaced after use. After the replacement, due to the need to detect the edge of the paper so that it can be printed on it accurately, and because the existing paper feeding function and printing function are all through the glue roller, so that in order to detect the initial printing position of the paper, it is necessary to start detection from the second section of bill printing paper or the second courier sheet, resulting in a waste of part of the printing paper, that is, wasting the first section of receipt printing paper or the first sheet Express orders, resulting in unnecessary waste, affecting efficiency and cost
