Hello, everyone. I'll answer your questions. Computer connection is not on the printer what's going on, computer connection is not on the printer is what reason this many people do not know, now let's take a look at it!

Answer:

If you can't find the printer you want when searching for available printers, you can click the printer you want is not in the list, enter the specific name of the shared printer, click Next, and then follow the instructions; to ensure that the printer driver is installed correctly on your computer, you will be prompted to install it if you are not connected to the printer. Just follow the instructions. If the driver installation of the program is not normal, it will pop up to install the driver and follow the prompts to install it.

2. Specific classification of printers:

3, printers according to the data transmission mode can be divided into serial printers and parallel printers. According to the working principle of the printer, the printer is divided into two categories: impact and non-impact. Character string dot matrix characters without impact printers are mainly inkjet printers and thermal printers. Inkjet printers are the most widely used printers, and their basic principle is that charged inkjet mist dots are deflected by electrodes to form the desired fonts directly on paper. Its advantages are that the printing spots of characters and images are much smaller than those of dot matrix printers, so the resolution of character spots is high, the printing quality is high and clear, and the character size and font can be changed flexibly and conveniently. Plain paper can be printed, and some products can be printed directly with this typewriter. Print speeds of up to 500 characters per second. Charge control type (high voltage type) and random inkjet type (negative pressure type) inkjet technologies are widely used, and dry inkjet printing technology has emerged. Thermal printer, pulse current flows through the print head point resistance generated by heat transfer to thermal paper, thermal paper heat discoloration, so as to print characters and images. Its main features are noise-free, light compact, clear printing, the disadvantages are slow speed, poor handwriting preservation. Linear dot matrix character non-impact printer mainly includes laser, electrostatic, magnetic, LED printer; laser printer, laser beam emitted by laser source enters optical system after being modulated by acoustooptic deflector controlled by character dot matrix information, rotating photosensitive drum is scanned transversely by polygonal prism, electrostatic latent image of character or image is formed on photosensitive film layer on photosensitive drum, and then required character or image is obtained on paper after development, transfer and fixation. The main advantage is that the printing speed is fast, up to 20,000 lines/minute or more, and the printing quality is high. Low-noise, plain paper can be used to print characters, graphics and images. Because of the fast printing speed, from a macro point of view, it is like printing one page at a time, so it is also called a page printer. Electrostatic printer, applying pulse voltage directly to special paper with a layer of dielectric material, obtaining electrostatic latent image on dielectric, forming characters and images by developing, heating and fixing, characterized by high printing quality, indelible handwriting, long-term preservation, low power consumption for generating latent image, no noise, simple and reliable, but using special paper, high cost; Magnetic printer is the application and development of electronic copying technology. It forms latent image of character by magnetic sensitive medium without high power laser source. Its advantages are insensitive to humidity and temperature changes, printing speed up to 8000 lines/min, simple structure and low cost. LED printers work similar to laser printers, but use LEDs as light sources. Due to the use of LEDs, cost and power consumption are reduced.

This is the end of this article, I hope it helps everyone.
