WIFI POS Printer Wholesale

Printing speed is an important parameter, especially for users with large amount of printing, which will seriously affect the time spent on POS Printer Brazil. Each manufacturer has different test conditions for this indicator. Some manufacturers published this indicator as the test result when connecting to external power supply, rather than the test result when using battery power supply. Users had better judge according to the actual printing speed.

Wireless communication protocol

POS Printer Russian is mainly divided into Bluetooth, infrared and WiFi. When choosing portable note printer and upper computer, the matching of both sides should be considered

Portable Printer Supplier

The black mark detection technology is used to locate when printing the template printed bill. It can be understood as the starting or ending position of each document. The single black mark detection technology is widely used. Some manufacturers use the double black mark detection technology. Compared with the single black mark detection technology, the double black mark detection technology has the advantage that it can realize the multi linked bill template printing. The so-called multi linked bill means that multiple documents of the same or similar type need to be printed each time, but the purpose of each document is different, so it is necessary to distinguish the starting printing position of these documents. The typical one is the traffic police ticket, which usually needs to print three copies, so it needs to use the double black mark detection technology.

There are two kinds of common printing width: 58mm and 80mm. 58mm portable note printer prints less content per line, 80mm prints more content, and the reading effect is much better. If only printing the list documents, the printer with a width of 58mm is generally used. If printing law enforcement documents or tickets, the printer with a width of 80mm is generally used.

Battery life

The Ios Printer Supplier is usually affected by three factors, one is the battery capacity, the other is the print length of the first charge, and the third is the power consumption when not printing. One charge printing length refers to the length of documents that can be printed when the printer is full of one charge; the power consumption when not printing will also affect the battery endurance. Some portable POS Printer will enter the sleep mode when not printing, at this time, the power consumption of the printer will be greatly reduced, which can effectively extend the use time of the battery. Battery endurance is not the higher the better, because the stronger the endurance, the larger the battery capacity, the larger the volume and weight will increase, and the best WIFI POS Printer quantity according to the specific needs is selected. Generally, the length of one charge printing can meet the needs of two days is better. If the printing quantity is too large, it must also meet the printing quantity of at least one day.

Biological activity of food colour Crocus sativus

Sweet Potato Powder has been proved that saffron has anticancer effect. The Spirulina Powder effect of the total extract of saffron ethanol and different components of saffron on the growth of human tumor cells in vitro was studied. The results showed that the half lethal dose of different components to HeLa cells were: Capsicum Oleoresin 2.3mg/ml of saffron dry stigma extract, 3 mmol / L of saffron, 0.8mmol/l of saffron aldehyde and 3 mmol / L of saffron bitter.

Modern research has found that saffron preparation has obvious anti-cancer and anti-cancer ability, and its anti-cancer mechanism may be to destroy the synthetase system, that is, to destroy a protein link medium which is essential for cell synthesis, so as to inhibit the synthesis of and, and achieve the effect of inhibiting the growth of tumor cells.

Ferulic Acid, crocin also inhibited the activity of protein kinase and the expression of proto oncogene. It was found that saffron extract can inhibit the growth of human tumor cells. The results showed that the cells treated with saffron had swelling and plasma membrane rupture, which indicated that the cytotoxicity of the cells might be caused by the absorption of extracellular fluid. Considering water solubility and high inhibition, crocin is considered to be one of the most promising cancer drugs in crocin.

Garcia Olmo et al. Used crocetin and carotenoid glycosides extracted from Crocus drying stigma for a long time to treat rats inoculated with colon cancer. It was found that crocetin and carotenoid glycosides can prolong the life span of female rats and slow down the growth rate of cancer cells, but they have no effect on male rats. Immunoserum analysis showed that the two compounds had only slight toxicity to kidney.
