There are two types of photo printers: thermal foaming photo printers, whose principle is to evaporate when the temperature rises. It is characterized by low printing accuracy, generally 600DPI, better 1200DPI, bright colors and slow speed, generally 5-9 square hours.

This kind of photo machine has a domestic 750 series photo machine with an accuracy of 600DPI. At present, the price is around 4500-8000, and the average price is around 5000, but the performance of this photo machine is not very stable. Sometimes it is easy to burn the nozzle if you buy it badly, and the speed is 5-6 square hours.

There are also some thermal foaming photo machines in Hong Kong and Taiwan provinces, such as Li Yong 860, Mabel 860, Liwei 860 and Magic Color 860 in Taiwan Province Province. In fact, the internal components are the same, but the brand and appearance are a little different, and the performance is similar. They are all assembled in Guangzhou factory, and the accuracy is greatly improved compared with 750. That's 1200DPI, and the nozzle. But the price of nozzle and ink is higher than 750. The ex-factory price of the machine 10000, which is the price for the dealer. Generally sell 15000- 18000. Speed 7-9 square hours.

This category is collectively referred to as domestic photo machines.

There is also a piezoelectric motor, whose principle is to use current to make ink seep out for printing. It is a technology invented by the Japanese, which is characterized by high printing accuracy and high speed. Generally, you can print 9- 12 square meters in one hour, and the performance is very stable. A nozzle can be used for 1-2 years, but it is very expensive, about 8,000-120,000 yuan each.

The photo machine can be used outdoors, so it is ok, that is, the ink is oily, but this is only a few photo machines that can be used, such as the magic color photo machine and so on. Moreover, the effect is relatively poor, and it affects the life of the nozzle and the photo machine, and it is not easy to use in principle.
