This article is to share with you about whether printers can only print pictures but not documents. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

No, the printer can print both pictures and documents. The printer is one of the output devices of the computer, which prints the calculation results or intermediate results of the computer on paper in accordance with the prescribed format with numbers, letters, symbols and graphics that people can recognize.

No, the printer can print both pictures and documents.

The printer (Printer) is one of the output devices of the computer, which is used to print the results of computer processing on the relevant media.

The printer was invented by John Walter and Dave Donald. A device that prints the results of a computer operation or intermediate results on paper in a prescribed format in numbers, letters, symbols, and graphics that people can recognize. Printers are developing in the direction of light, thin, short, small, low power consumption, high speed and intelligence.

There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many kinds of printers, such as whether there is a hitting action on the paper according to the printing element, the percussive printer and the non-percussive printer. According to the print character structure, it is divided into full-width character printer and dot matrix character printer. Separate the serial printer and the line printer according to the way that a line of words is formed on the paper. According to the technology adopted, printers are divided into cylindrical, spherical, inkjet, thermal, laser, static, magnetic, light-emitting diode and other printers.

Needle printer

Needle printers have played an important role in the history of printers for a long time, from 9 to 24 stitches, it can be said that the history of needle printers runs through these decades. The reason why needle printer can be popular for a long time is inseparable from its extremely low printing cost, good ease of use and the special purpose of document printing. Of course, its low print quality and high working noise are also the root causes of its inability to meet the needs of high-quality and high-speed commercial printing, so it can only be seen in banks, supermarkets and other few places used for ticket printing.

colour inkjet printer

Color inkjet printer has occupied the vast middle and low-end market because of its good printing effect and low price. In addition, inkjet printers also have more flexible paper processing capacity, in the choice of printing media, inkjet printers also have certain advantages: they can print envelopes, stationery and other ordinary media. it can also print a variety of film, photo paper, CD covers, roll paper, T-shirt transfer paper and other special media, which will be introduced in the following section.

Laser printer

Laser printer is a new product of high-tech development, and it is also expected to replace the inkjet printer, which is divided into black and white and color. It provides us with a higher quality, faster and lower-cost printing method. Among them, the price of low-end black-and-white laser printer has been reduced to a few hundred yuan, reaching a level acceptable to ordinary users. Its printing principle is to use the raster image processor to generate the bitmap of the page to be printed, and then convert it into electrical signals and other pulses sent to the laser transmitter, under the control of this series of pulses, the laser is emitted regularly. At the same time, the reflected beam is sensitized by the receiving photosensitive drum. A dot is produced when the laser is emitted, and it is blank when the laser is not emitted, so a line of dots are printed on the receiver. The receiver then rotates a short fixed distance to continue to repeat the above operation. When the paper passes through the photosensitive drum, the colorant on the drum is transferred to the paper and printed into a bitmap of the page. Finally, when the paper passes through a pair of heating rollers, the colorant is heated and melted, fixed on the paper, and the whole printing process is completed, which is accurate and efficient. Although laser printers are much more expensive than inkjet printers, laser printers are much cheaper in terms of the cost of printing per page. The price of color laser printers is generally around 2000 yuan.

Other printers

In addition to the above three most common printers, there are several professional printer models, such as thermal transfer printers and large format printers. The thermal transfer printer uses transparent dye to print, and its advantage lies in professional high-quality image printing, which can print continuous-tone pictures close to photos, which are generally used for prepress and professional graphics output. Large format printer, its printing principle is basically the same as inkjet printer, but the print width can generally reach more than 24 inches (61cm). Its main use has been concentrated in the field of engineering and construction. However, with the improvement of the durability of its ink and the increase of graphic resolution, large format printers are increasingly used in the fields of advertising production, large photography, art portraits and interior decoration. and become an important member of the printer family.

American ZCorp is a professional 3D printer manufacturer, which produces the world's fastest 3D printer and the only true color 3D printer. Coupled with the extremely low cost of consumables, it is favored by many users around the world. Israel 2Objet rapid prototyping machine PolyJet technology, Eden series 3D printers, 16 micron ultra high resolution, FullCure series materials, is the most convenient 3D printing rapid prototyping machine with the highest molding accuracy (layer thickness only 0.016mm) in the world.
