What is a printer, its definition, uses and types? 2022
What is a Printer How Many Types of Printers Are There? What is the function of printer? When was the printer invented? These are some questions, which are asked to the student learning new computer, today we will know the complete information of printer, printer is one such device which is most popular in computer system. The job of a printer is to print the output information of the computer. The printer removes the hard copy to the user.
Without a printer, a computer user cannot extract print material from a lot like reports, letters, resumes, brochures, posters, flyers, railway tickets, invoices, so printer is a very important device. So in today’s article we will know what is printer in hindi? What is Printer? Types of printers, what device is the printer, full information about how to use the printer
What is Printer?
Printer is the most popular output device. Printers provide information in a permanently readable form. The printer generates hardcopy by printing the text and graphics output from the computer onto paper or other media.
There are many different types of printers priced differently depending on size, speed, and usage. In general, more expensive printers are used for more frequent printing or high-resolution color printing. The printer installed in a personal computer is differentiated as an impact or non-impact printer.
Earlier Impact printers worked like automatic typewriter keys. This was called a character printer, a character printer used to print one character of text at a time. They are low speed printers. A dot matrix printer, an impact printer that strikes paper one line at a time, is a popular low-cost printer option.
The most famous non-impact printers are inkjet printers and laser printers. Inkjet uses ink cartridges and prints ink onto paper, while laser printers use laser beams to print through ink toner from drums to paper, similar to a photo copier.

History of Printer
The first computer printer was designed in the 19th century by the father of the computer, Charles Babbage, for his mechanical computer difference engine.
The typewriter is then considered a precursor to the printer and keyboard, invented by Christopher Sholes in 1868. The first high-speed printer was developed in 1953 by Remington-Rand. It was designed to be used with UNIVAC computers.

Dot matrix printer was first introduced in the market in 1957 by IBM. The first electronic printer was the EP-101, invented by the Japanese company Epson, and released in 1968. The first dot matrix impact printer was developed by Centronics in 1970 and ran through Centronics’ interface.
The first inkjet printer was developed in 1976 by Hewlett-Packard, however, inkjet printers did not gain popularity until the mid-1980s. Hewlett-Packard introduced its first laser printer, the HP Laser Jet, in 1984, a low-cost printer. In the same year, Hewlett-Packard introduced the first thermal inkjet printer, the HP Think Jet.
Many modern 3D printers today use a technique called FDM (Fused deposition modeling), which was patented in 1988, developed by inventor Steven Scott Crump.
When was the printer invented?
Johannes Gutenberg’s contribution to the development of the word printed earned him the nickname “Father of Print”, after developing mechanical moving type printing around 1439.
He was a German inventor, printer, publisher and goldsmith who introduced printing to Europe with his mechanical movable-type printing press.
Types of Printer
Types of Printer Printers can be classified according to size, speed, function, resolution, cost and other characteristics. But all printers are broadly classified into the following two types:
- Impact Printers
- Non-Impact Printers
An impact printer is a type of printer that works by direct contact of an ink ribbon with paper. It works like a typewriter. Impact printers use an electro-mechanical mechanism that strikes a metal or plastic printhead against the ink ribbon and paper, causing the ribbon to press against the paper and print the text or character.
Impact printers are very noisy due to the use of electro-mechanical components, and are slow to operate, although this printer delivers economical prints, which is best for everyday bulk printing. It is used by banks, railways and other large organizations. Impact printers are mainly classified into the following two types:
- Character Printers
- Line Printers
A printer that prints one character at a time. That is, these printers use only one stroke of the hammer or print head at a time. These are low speed printers and their printing speed is in the range of 30-600 characters per second. These specialized character printers are dot matrix printers whose print head pins form characters. Character printers are classified into two types:
- Dot Matrix Printer (DMP)
- Daisy Wheel Printer
Dot Matrix Printer (DMP)
A dot matrix printer is an impact character printer that prints using a fixed number of pins or wires. Usually the pins and wires are arranged in one or several vertical columns.
The pins hit an ink-coated ribbon, and force contact between the ribbon and the paper, so that each pin forms a small dot on the paper. The combination of these dots forms a dot matrix image.
Dot matrix printers use one or two columns of dot hammers that move across the paper. Hammers rapidly press the ribbon into the paper, which causes the ink to accumulate. The more hammers, the higher the resolution prints, for example 9-pin heads print draft quality text, while 24-pin head typewriters print quality output.
Speeds range from 200 to 400 characters per second (cps).
Daisy Wheel Printer
Daisy wheel printing is an impact character printing technique, invented in the 1970s by Dr. Andrew Gabor. It is a type of printer that produces letter-quality prints. Daisy-wheel printers operate on a method similar to ball-head typewriters. It uses interchangeable pre-built type elements, each typically containing 96 glyphs, to generate high-quality output.
It is 2 to 3 times faster than premium typewriters. A daisy wheel is a disc made of plastic or metal with character letters along the outer edge. To print a character, the printer rotates the disc until the desired letter is in front of the paper. Then a hammer strikes the disc, forcing the character to hit the ink-ribbon, leaving an imprint of the character on the paper.
Due to its resemblance to a daisy flower, its name is considered to be a daisy wheel. Daisy-wheel printers cannot print images or graphics, and in general they are noisy and slow, printing from 10 to about 75 characters per second.
A line printer is a high-speed impact printer that first prints a full line of text, then moves on to the next line. Line printers have the capacity to print 300 to 3000 lines per minute. It prints very fast. Large organizations use line printers, where a lot of prints are taken out cheaper and in less time. Line printers are classified into three types:
- Drum Printer
- Chain Pinter
- Band Printer
- TallyGenicom Line Printer
Drum is a line printer technology that uses character images formed around a cylindrical drum as its printing mechanism. A drum printer consists of a circular rotating cylindrical drum with characters on its surface.
The paper is placed between the ribbon and the head (hammer), with several hammers on the front of the drum. The drum spins at a very high speed and the character is printed by activating the appropriate hammer.
A chain printer is an impact line printer, the print element in a chain printer is a metal band or chain with an embossed letter, which rotates horizontally across the front of the paper.
A complete chain consists of five sections, each section containing 48 characters. As the print chain spins, the timed print heads strike the paper with the ink-ribbon at the appropriate character.
Chain Printer is one of the fastest impact printers, which can print from 300 to 3000 lines per minute. This printer also makes noise, as they print the character by hammering action.
Band printers, also known as belt printers, are a type of impact line printer in which fonts, letters and timing marks are engraved on a steel band. The band consists of a fixed set of embossed characters that can be changed simply by changing the band.
During output, the band moves horizontally across the back of the paper, and a hammer strikes the band opposite the appropriate character, pushing it through an inked ribbon and onto the paper, and the character is printed. Band printers can print from 300 to 2000 lines per minute. Band printers are considered better than drum printers in terms of price and performance.
Non Impact Printer A non-impact printer is a type of printer that does not hit or strike the ribbon to print. Non-impact printers do not have a hammer to hit the print heads on the ribbon containing the ink. These types of printers do not use any ink ribbon to print.
Non-impact printers fall into three main categories: Laser printers use a laser beam to attract toner to an area of paper. Ink-jet printers spray a jet of liquid ink
These printers are classified by their efficiency, speed, quality, cost of operation as follows:
- LaserJet Printer
- InkJet Printer
- Multi-function Laser Printer
- Photo Printer
- Thermal Printer
- 3D Printer
- LED Printer
- Barcode Printer
A laser printer is a popular type of personal computer printer that uses non-impact photo copier technology. It produces very good quality printed material from a computer using a very powerful controlled laser beam.
Laser printers were developed by the Xerox company in the 1960s, when the idea of using a laser to draw images onto a copier drum was first introduced. Laser printers are still widely used in large offices because they are traditionally more efficient and print at higher speeds and quality.
A laser printer uses electrostatic charge to create an image on a photosensitive drum; the laser exposed areas attract toner (ink powder). The drum transfers the toned image to the paper.
It attracts a dry powder called toner onto the paper which is then fused into the paper using hot rollers.
Ink Jet Printer
Inkjet printer is a non-impact printer, ink jet printer also produces images with tiny dots like laser and dot-matrix printers. This printer shoots droplets of ink directly onto the medium. Today, most inkjet printers are color printers that use four inks packaged in separate cartridges: cyan, magenta, yellow, and black (CMYK).
Inkjet printers each have a print head with thousands of tiny holes. These tiny holes move microscopic droplets of ink onto the paper in the printer at speed. As the print head moves vertically in the machine, the paper passes vertically and the print is done.
Multi Function Laser Printer
A multi-function printer is a type of multi-purpose printer, also known as an all-in-one printer. Multifunction printers are often capable of performing printing, copying, scanning and faxing tasks. It simplifies completing an office or household task, a multi-function printer has an in-built scanner, fax, photo copier and other devices connected to the printer.
Multi-function printers do a lot of work in one equipment and do not require much space. It is an affordable tool for the home user and small business organization.
A photo printer is a type of inkjet printer that allows us to print photos. It is available in the photo printer market to print photos in different size media papers.
This printer is designed to print on white photo paper, and its ink is of high quality that will not leave the paper. It is a bit expensive inkjet, but provides the facility to print photos in small photo studio, home, office.
Some mobile photographers use it to print photos quickly. Nowadays photo printers also support wireless printing, and print from smartphones or any mobile device.
A thermal printer works by using heat to create an image on the paper. Thermal printers use a heated printhead to produce an image. The thermal printing process involves heating sensitive thermal paper with a special dye coating, which turns black when heated.
Other types of thermal transfer printing use hot ribbons, which produce longer lasting images. This thermal transfer printing process is known to produce highly durable and smudge-resistant prints.
Thermal printing is used in a wide range of industries for a wide range of transactions, including transportation and logistics, banking transactions, airline tickets, retail receipts, healthcare uses, school records and bar codes.
3D printers are modern and advanced printers, which are used to print 3D-objects. 3D printing produces a three-dimensional object from a CAD model or a digital 3D model. 3D printers are also called additive manufacturing printers or fabrication printers.
Rapid prototyping of 3D-objects and structures is made using direct source files from 3-D designing applications such as AutoCAD.
In recent years, 3D printing has evolved significantly, being used in fields such as manufacturing, medicine, architecture, art and design.
A plotter is a large-sized industrial printer, or a machine, that produces drawing vector graphics. Plotters draw lines on paper using a pen, or in some applications, use a knife to cut materials such as vinyl or leather that are also considered cutting plotters.
Plotters can work on very large sheets of paper while maintaining high resolution. They can work on a wide variety of flat materials, including cutting plywood, aluminum, steel sheets, cardboard and plastics.
Inkjet plotters print large posters, banners and vector graphics. Plotters are much more expensive than traditional printers.
An LED printer is a type of computer printer that is similar to a laser printer. Such a printer uses a Light Emitting Diode (LED) system as the light source in the printhead instead of the laser beam used in laser printers.
The LED mechanism is much simpler than its laser printer counterpart. Like laser printers, LED printers have a photoreceptive drum whose surface is positively charged with static electricity by a high voltage wire.
The sheet of paper is then passed between two heated rollers, fusing the toner onto the page before it comes out of the printer. LED printers range from inexpensive personal printers to giant digital printing presses that print over 700 pages per minute. We do.
Bar Code Printer
Barcode printer is a label printer, barcode printer is used to print barcode labels or tags. Barcode printers use one of two types of technology, which include thermal technology or thermal transfer printing technology.
Barcodes produced with barcode thermal printers are more likely to become unreadable when exposed to elements such as heat, sunlight, and chemicals, and therefore barcodes created with thermal technology do not have a longevity.
Printing quality for longer print times and good label material makes barcode prints a bit expensive. Barcode printers range from small business to industrial uses, and are commonly used to label products.
The barcode label is then scanned with a barcode reader. Thermal Transfer (TT) type label printers are the industry preferred choice for high quality, long lasting labels.
By now you must have known that what is a printer? What are the types of printers? What is the function of printer? What are the functions of a laser printer and how the printer is used.
There are more printers in printing technology, which are available in the market according to the need, such as passbook printer, spark printing, all these printing equipment are different.
What is Printing Speed?
Desktop and workgroup printers for business use different technologies, with each printer having a set speed. Each of which printers are known for cost, speed and quality. All printers can be classified by speed
We will classify the printing speed as follows:
- Character Per Second (CPS)-Serial Printer
- Line Per Minute (LPM)-Line Printer
- Pages Per Minute (PPM)-Page Printer
Character Per Second (CPS)-Serial Printer
In early times, the speed of all printers was measured in characters per second (CPS) or character per minute (CPM). This term used to determine the number of characters a serial printer could print per second.
These are all Dot Matrix printers, whose speed used to be 50-500 (CPS). Most dot-matrix printers offer different speeds depending on the print quality you want.
Line Per Minute (LPM)-Line Printer
Line printer speed is measured on Line to Minute (LPM) basis. These printers used to decide how many lines they could print in a minute.
Line printers print a complete line at a time and its speed is in the range of 300 to 3000 (LPM) lines per minute. These are very high speed printers.
Pages Per Minute (PPM)-Page Printer
Today all modern printers support Pages Per Minute (PPM). We can also call all these printers as page printers. A page printer is a laser printer and each model of laser printer is designed to print an approximate number of pages per minute.
Black and white printing is between 21 and 42 (PPM) pages per minute on a typical home laser printer.
printer ka full form
Printer does not have an acronym word, derived from “a signet or seal” in the 1500th century, “prenten” meaning “to make an impression, press upon or into” (as with a seal, stamp, etc. .) In simple language “to make an impression, press, or in” (with a seal, stamp, etc.) means “to set a mark on any surface” (including writing).
You can also say so as a mechanical device that prints, presses or stamps by impression.

Which device is the printer?
A printer is an output device. Printer is an output device. Just as any device connected to the computer provides us with output data, it is called an output device, in the same way a printer is an output device.
Use of printer
Printer is an output device and it is used in many fields. A printer is used for many purposes from home user to industry.
Different types of printers include 3D printers, inkjet printers, laser printers, thermal printers, dot matrix printers and passbook printers which are used as per the requirement. We will mention the use of printers in the following four ways:
- Personal Uses
- General Use
- business purpose
- General uses of a wide format printer
Printers at home are used for personal work and study like printing students’ projects, family photo printing, greeting making, personal letter print.
General-use printers are designed to print for a variety of print jobs. Simple text letter, email print, document print.
Printing a flyer for rent, the type of things that don’t require high quality images, are perfect for this type of general use laser printer.
These printers are generally large format printers, capable of printing on most media sizes. As in business use always looking for efficient, efficient, fast print speed and ability to handle high volume production.
Large and small organizations use other types of printers for everything from office work to billing.
General uses of a wide format printer Wide format printers are used in large industries such as printing of banners, billboards, signage, billboards, film posters and graphic designs.
It has many uses, we can call all these printers as plotters, eco-solvent printers. It is used from advertising industry to interior design industry.
