how to create a new template of A4 paper special price card for fresh supermarket on the computer, and print it out. Next time, you can use it repeatedly to open the template, change the barcode price and name, and then print it

Then you can use PS, and use as much canvas as the price card. The background and price figures are not on the same floor, so you can change them separately. Just print a PDF file for the printing company to print when plotting. How to make a supermarket shopping receipt

To make a supermarket shopping receipt, a thermal printer is generally used, which is also suitable for printing product labels. Supermarket receipt paper and ATM receipt paper all use the same kind of paper, which is called thermal paper. Common thermal paper sizes in life are generally 57 mm and 81 mm wide. 57 mm wide is generally used for mobile POS machines or supermarket cashiers, and 81 mm wide is used for printing orders such as catering. The thickness of paper is measured in the same way as A4 paper, and it is also expressed in grams per square meter. There are many common thicknesses, such as 55g/O, 65g/O and so on. Thermal paper paper has three layers of substances with different chemical properties. The bottom layer, the paper base, is prepared for the adhesion of heat-sensitive substances after a certain surface treatment of ordinary paper. The second layer is a heat-sensitive coating, which is a collection of various chemicals and develops color after being heated. The third layer is the protective layer, which is used to protect characters or patterns from being destroyed by the outside world.

The thermosensitive layer is mainly composed of three chemical components, namely leuco dye, developer and adhesive. At normal room temperature, these three components will not react chemically, but when the thermal paper meets the hot print head, the leuco dye will react chemically with the developer, and then the information such as words we see will be presented. The most important thing is from the actual printing quality, good thermal paper, clear text. Poor thermal paper, the text part is easy to be missing and difficult to identify. The advantage of using thermal paper is that the thermal printer with thermal paper does not need to use color-developing materials such as carbon tape, so it is very convenient to replace the thermal paper after the printing paper is used up.

However, thermal paper also has some disadvantages. Because the information such as characters on thermal paper is generated by chemical reactions, and these chemicals are generally not very stable, the printed receipts will become thinner and thinner with the extension of storage time.
