What are the 10 types of printers
My dear readers and visitors In today's blog we are going to talk about an output device called a printer. What are the 10 types of printers and how many types are there. All of you must have heard the name of this device, along with this you must have used it in your life and will know about its types and how it works. So let's know - What are the 10 types of printers.
It accepts input commands by users on computers or other devices to print various types of documents like - text, photos, images etc. For example, in the field of school, coaching, college, company, home, banking and various types of fields, prepare a soft copy of the project or report on your computer or laptop and print it with the help of a printer and get it in hard copy form. Let's take what we call photo-copy in the language of common-speak. Therefore
A printer is an output device used to print hard copies of electronic data stored in a computer or other device into soft copies.
Types of Printer
Impact Printer
It is a type of printer that works by direct contact of an ink ribbon with paper. When a metal or plastic head strikes an ink ribbon, a metal hammer or a print head strikes a ribbon of ink, causing these printers to make a lot more noise than other printers. whereby the ribbon is pressed against the paper and the desired character (letter, number, dot, line) is printed on the sheet.
Types of Impact Printer -
1. Dot-Matrix Printer
A Dot-Matrix printer is a type of printer that uses a pin bearing an ink ribbon to print. These printers are generally considered outdated, as they cannot produce high quality prints and are expensive as well. Since they use effects for printing, they can be used to print multiple copies of text at the same time with the help of carbon copying. Therefore, they are mostly used in places where multipart forms are required.
2. Daisy-Wheel Printer
A daisy wheel printer is a specific type of mechanical effects printer popular in the 1970s that used separate letter, number, and symbol keys to print text on paper. The test used in this are printers with solid fonts, the head of this printer is in the form of a round circle made of plastic, whose shape is similar to a daisy (hibiscus) flower. For example, typewriter is also the main example of a daisy wheel printer.
3.Chain Printer
It is a printer in which a fast-rotating chain made of metal and a letter is embossed on each link of this chain, the chain moves in the horizontal direction and at the same time the paper moves vertically relative to the chain, Whenever we have to print any letter at any place, then hammer is struck at that place and that letter is printed on the paper, it is a good quality printer.
4.Drum Printer
It is an Impact printer. In the modern digital age, refers to a variety of printer designs that involve drum installation or setup. In this type of printers there is a cylindrical rapidly rotating drum, whose entire surface is covered with letters in a line. As this cylindrical drum rotates, the character is printed on the paper. The two very different types of drum printers represent milestones in the process of creating more sophisticated and advanced printers as digital technologies evolve.
5. Band Printer
It is a printer that has a metal band, just as a chain printer has a chain, in the same way there is a steel band in place of the chain. On which the characters are inscribed. During output, the band moves horizontally across the back of the paper, and a hammer strikes the opposite band of the appropriate character, pushing it through an inked ribbon and onto the paper.
It can print from 300 to 2000 lines per minute.
Types of Non-Impact Printer
1. Laser Printer
A laser printer works like a photocopying machine. Laser printers have a special function to print any image or text. In this, a laser beam is thrown onto a glass. This glass now puts them on top of a drum. This drum is coated with a special type of toner or ink powder. Using tiny dots, the laser beam takes information from the computer and passes the positive charge to the drum. This drum now goes without charge. Light Emitting Diode (Light-Emitting Diode-LED) printers are similar to laser printers in operation, when a document is sent to the printer, a laser beam uses electrical charges to "draw" the document onto a selenium-coated drum does. After the drum is charged, it is infused into toner, a dry powder type of ink.
2. Inject Printer
Inject printer is a non-impact as well as a computer hardware peripheral that can be connected to a computer system wirelessly or wired. Inkjet printers are mostly used in home and small offices, as they are capable of performing basic multi-tasking like print, scan, photocopy etc.
Inject printer works as the principle of inkjet technology. This technique involves spraying ionized ink directly onto paper using magnetic plates and that is fed through a printer. The print head spins back and forth, and sprays thousands of these tiny droplets onto the paper. Inkjet printers are called the category of those printers in which printing is done with the help of inkjet technology. In this technology, ionized ink is sprayed over the paper as directed by a magnetic plate, which is fed through the printer.
Since inject printers are very affordable as compared to other types of printers, they are commonly used according to home and business printers.
The first Inject printer was introduced by Hewlett-Packard in 1976.
3.Thermal Printer
Thermal Printer is a digital printing process that prints images on coated thermochromic paper. When paper passes over a thermal print head, thermochromic paper darkens in areas where it is heated, forming an image. Two-color thermal printers can print both black and an additional color by applying heat at two different temperatures. You don't even need to refill ink again and again. In direct thermal printers, no ink, toner, or things like ribbon are used. Their simple design makes thermal printers durable and easy to use. In thermal printing, a thermal printhead applies heat to a ribbon, which melts the ink on the material to form the image/photo.
4.Portable Printer
This is such a printer that we can easily carry around, can come in the category of portable printer. But especially hand-held barcode printers and small photo printers, which we often see at tourist places, are called portable printers. These printers are used to take instant photos from digital cameras. You must have seen this printer in a mall or any shop or any school, or college or other place, when you swipe the card in a swipe machine, a small receipt is received, it works like a portable printer. Or else the person who comes to your house to cut the electricity bill receipt, then you must have noticed that he hangs a device on his waist and cuts you a receipt from it.
Using this printer, we can print anything from photos to any place sitting anywhere, we can easily complete our work.
