Why use thermal paper?

Question 1: What is the function of thermal paper? Why use thermal paper? Thermal paper is used as the communication carrier of words and graphics on fax machines, that is, as fax paper; Used as recording materials in medical and metering systems, such as ECG paper, heat sensitive instrument recording paper, etc. Printing paper for Internet terminals; In commercial activities, it is used to make trademarks, identification codes (POS), etc., in which the amount of fax paper accounts for the largest proportion.

The principle of making thermal paper is to coat a common paper base with granular powder, which is composed of colorless dye phenol or other acidic substances, and the middle is separated by a film. Under the heating condition, the film melts and the powder is mixed to produce a color reaction. The color handwriting on thermal paper is unstable and easy to fade, which makes it difficult to identify the contents of the document.

Commonly used lottery tickets are made of heat-sensitive paper.

Ordinary thermal paper is not suitable for long-term storage, and good thermal paper can be stored for 30 years or even longer.

Question 2: Why do movie ticket stubs have to be printed with thermal paper now? In the original cinema, one movie was shown at a time and tickets were bought at one or two windows. Movie tickets are printed in advance, so it is almost impossible to choose seats, or it takes a lot of time to find them. If it doesn't sell this time, the ticket will be invalid. At present, there are so many people in the cinema and so many halls showing movies at the same time. You can buy tickets at multiple windows at the same time, and you can choose seats. It is also possible to change movies temporarily, so the efficiency of using tickets printed in advance will be unimaginable. The advantages of thermal paper are high printing speed and low failure rate. For cinemas, movie tickets are only valid for two or three days, purely to increase costs and consider what to save. I think it is a very good way to take photos and send cloud disks, which is both environmentally friendly and convenient.

Question 3: Why do supermarkets use thermal paper to print receipts, and why don't they use printers? You mean a laser printer or an inkjet printer,

First, because of the cost, the thermal paper printer has low cost and low maintenance cost. There is no need to add ink like an inkjet printer, change the print head, or add toner like a laser printer, and the power consumption is many times lower.

Second, the stability is good. After all, the working principle is simple, the mechanical structure of circuit design is simple, it is not easy to break down and the system will not collapse.

Third, the occupied space is small. Don't laugh at this answer. It would be embarrassing to put the laser printer in such a small place as the supermarket checkout counter.

Question 4: Why should thermal paper be used for the invoice given by SF Express? Because SF Express is awesome. In China, no invoice is thermal paper, so only thermal paper is used along the invoice.

But the advantage of using thermal paper is that the printing speed is fast.

Question 5: What's the difference between coated paper and thermal paper for barcode machine? Copper tripod paper is printed with carbon tape and can be preserved for a long time.

Thermal paper can be printed without carbon tape, but the storage time is not long, but one kind of thermal paper has a long storage time of 2 years, but it is more expensive;

Question 6: Why does heat-sensitive paper turn black when printing with ordinary printers? The toner is transferred to the fiber paper through the toner cylinder, and then fixed on the paper after being baked at a high temperature of about 180 degrees, and the toner enters the fiber of the paper. Paper with smooth surface is not suitable for laser printing, even if it is barely printed, because toner can not enter the paper fiber, it is easy to fall off, and words will fall off. The thermal paper you used can't be used. When using a laser printer, the thermal paper is heated at high temperature in the fixing part, and the thermal agent on the surface of the paper will make the whole paper black (some will turn blue), which is caused by the imaging principle of thermal paper.

Question 7: Why should express delivery be printed on thermal paper? A small printed list is attached to the parcel. Because thermal printing has many advantages,

For example, the speed is high and the noise is low, and the portable thermal printer is also convenient for printing anytime and anywhere.

Thermal printing will gradually replace the traditional express bill in the future.

In addition, if thermal printing is used in combination with printing tools such as typing,

You can play a single order for one second first,

Very fast.

Question 8: Whether to use thermal paper or A4 paper for fax machine should not be decided by fax machine, because a fax machine can only correspond to one kind of paper.

So your question should be whether the fax machine of thermal paper is better or plain paper (A4).

In fact, these two fax machines have their own advantages and disadvantages. Thermal paper fax machine has low cost and does not need other consumables except thermal paper. Besides, the machine is also cheap (relatively speaking). The disadvantage is that the resolution of the fax received by the thermal paper fax machine is poor, which is not suitable for long-term storage and will fade after a long time;

Ordinary paper (A4) fax machine generally has high speed, high resolution and good copying effect, but its disadvantages are high machine cost and expensive products.

So you should choose what you need reasonably according to your actual needs.

Question 9: Do pos machines using thermal paper need ribbons, dear? The pos machine of thermal paper can be used as long as there is thermal paper, and no ribbon is needed.

Ribbon is used for stylus printers. You can type multiple sheets of paper.

So, you can try it. You can bake a thermal paper with a lighter and see how it works. . .
