What Is a Commercial Printer?

Printer (Printer) is one of the computer's output devices, used to print the results of computer processing on the relevant media. There are three indicators for measuring the quality of a printer: print resolution, print speed, and noise. There are many types of printers, which are divided into impact printers and non-impact printers according to whether the printing element has a striking action on the paper. According to the print character structure, it is divided into full-width character printers and dot-matrix character printers. Serial printers and line printers are formed on the paper in one line. According to the technology used, it is divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light emitting diode and other printers.

Printer installation is generally divided into two parts, one is the connection between the printer and the computer, and the other is the installation of the printer in the operating system

1. In case the printer generates heat, smoke, strange odor, abnormal sound, etc., please immediately cut off the power and contact the information personnel.

2. No other items are allowed on the printer. When the printer is not used for a long time, please unplug the power plug from the power outlet.

3. As a precaution, unplug the power plug from the outlet when there is a thunder nearby. If plugged in, the machine may be damaged.

4. When the paper and ribbon cassette are not set, printing is prohibited. The print head and print roller can be damaged.

5. The print head is hot. Do not touch until the temperature has dropped. Prevent burns and injuries.

6. Do not touch the metal part of the print cable connector and the print head.

   Printer helps stem cell development

   Getting stem cells and culturing them into the desired cells is not easy, because human tissue is very complex and consists of a variety of different types of cells, which must be layered in the correct mode for normal operation. Scientists have come up with a system where they place a layer of nutrient protein on a 2.54 cm square piece of glass and then use an automatically controlled inkjet printer to spray a small amount of protein on it into a special form that allows cells to Survival, development and differentiation. Then, when stem cells are developed on this mold, different cells are formed.

   To design a new cell printer, Calvert went to an electronics store and bought an inkjet printer, refitting its core components and installing it on a software-controlled device in the laboratory. Calvert said: "What you see in the middle of the machine is something similar to an inkjet box. However, instead of ink of various colors, the nozzle ejects different types of cell culture media. Despite this The cell printing device still uses the micro pin printing mode, but the cell culture medium is not damaged. "

   Calvert hopes that this technology will produce miniature organs for medical testing. He also hopes that in the future, humans will be able to produce transplantable organs according to their needs.

   13-year-old U.S. entrepreneur wins Intel venture capital

   A 13-year-old junior high school student in San Jose, California, Shubham Barnaji invented a braille printer. After reading a Braille financing leaflet, Banaghi was inspired to turn the high-tech version of Lego bricks into a device capable of printing Braille. He hopes to make the printer on a large scale someday, and it will cost about $ 350. This price is much lower than current Braille printers. In the summer of 2014, Barnaji tried to use Intel's Edison chip in this printer. Intel invited him to a conference in India to show users the use of Edison chips. In India, Banaji has caused a sensation. Intel executive Mike Bell announced at the time that Intel would invest in Barnaghi's company Braigo Labs. Prior to that, Barnaji's funding came from $ 35,000 provided to him by his parents.
