Printers are external hardware devices that take computer data and generate a hard copy. There are two main types: impact printers, which physically strike the paper, and non-impact printers, which create images without touching the paper. Dot-matrix printers are an older impact printer that forms images with an array of pins and is inexpensive but noisy with low print quality. Inkjet printers are popular non-impact printers that work by firing tiny droplets of ink and provide higher quality color output, while laser printers use a dry powder toner and an electrostatic process to produce very high quality black and white pages at a lower cost-per-page than inkjet printers.
Impact printers work by physically striking an ink ribbon to transfer characters to paper while non-impact printers like inkjet and laser printers avoid physical contact. Dot matrix printers use rows of pins to form characters as ink is transferred to paper. Laser printers use toner powder and heat to fuse characters onto paper at high speeds. The type of printer chosen depends on factors such as output volume, quality needs, location, and whether color or copies are required.
This document provides an overview of different printer technologies. It discusses the basic principles of laser printers and inkjet printers. Laser printers use static electricity to transfer toner powder to paper to create the printed image, while inkjet printers use thermal bubble or piezoelectric mechanisms to spray ink droplets. The document also describes various printer components like photoreceptors, toner, and fusers, and how they work together in the printing process.
The document defines and describes different types of printers: dot matrix printers print by striking an inked ribbon against paper like a typewriter; inkjet printers are the most common consumer printers that work by propelling ink droplets onto paper; plotters are specialized printers that use pens to draw vector graphics for applications like engineering; laser printers use a laser beam to define an electrostatically charged image on a drum for high quality text and graphics output.
The document discusses different types of printers including their key characteristics and functioning. It describes dot matrix printers, inkjet printers, and laser printers. Dot matrix printers work by striking the page with pins to form characters and can be classified based on the number of pins, characters per second, and interface. Inkjet printers work by spraying tiny droplets of ink onto paper and laser printers use a process of cleaning, charging, writing, developing, transferring, and fusing toner onto paper using heat.
Inkjet printers work by spraying tiny droplets of ink onto paper through nozzles. There are two main types of inkjet printing technologies - continuous inkjet which continuously sprays ink, and drop-on-demand inkjet which only sprays ink when needed. In drop-on-demand inkjet printers, a resistor heats ink at the bottom of an ink chamber until it vaporizes, forcing a bubble of ink out of a nozzle. As the bubble expands, it pushes the ink droplet onto the paper. Inkjet printers are commonly used, range from inexpensive to expensive models, can print in color or black and white, and have advantages like quiet operation and ability to print photos, but disadvantages include expensive replacement

A printer is an output device that prints text and graphics on paper. There are two main types of printers - impact printers and non-impact printers. Impact printers work like typewriters using pins or hammers to strike ink ribbons and transfer ink to paper, while non-impact printers use technologies like lasers and inkjets that print without physically striking the paper. Non-impact printers are generally faster, quieter and provide higher quality output than impact printers.
There are two main types of printers: impact printers and non-impact printers. Impact printers work by physically striking an inked ribbon against the paper, and include dot-matrix, daisy wheel, drum, chain, and band printers. Non-impact printers do not physically strike the paper, and include inkjet printers which spray ink onto paper, and laser printers which use a laser beam to attract toner onto the paper to form images. Dot matrix printers use print heads with pins that form characters by striking individual dots, while laser printers use a laser beam and toner to efficiently print high quality pages at speeds up to 437 pages per minute.
The printer is a computer peripheral that accepts text and graphics as input and prints them on paper. There are four main types of printers: impact, inkjet, laser, and plotters. Impact printers such as dot matrix printers work by striking pins against an ink ribbon to print characters. Inkjet printers spray ink through nozzles onto paper. Laser printers use static electricity and toner to transfer an image onto paper. Plotters are large printers used for technical drawings.

The printer also includes a paper tray, rollers to move the paper, and control circuitry to operate the mechanical functions. An inkjet printer provides benefits like low cost, high quality color output, and ease of use, but has limitations such as less durable print heads and high replacement costs for ink cartridges.

The Indian government has been working over the past few years to include elements of ITS in the transport sector. This standard ensures the optimal operation of the current transport infrastructure. It also increases the efficiency, safety, comfort, and quality of the system. That is why the government created the AIS-140 standard. Compliance with this standard means all vehicles used for public transit must have panic buttons and vehicle tracking modules installed. Nevertheless, in future in the standard protocol of AIS-140 you can expect fare collection and CCTV capabilities.

non-impact
• Impact printer is a printer that produces a letter or
image using in physical types.
• Types of impact is dot matrix(that the result as group of

Engineer, Gary Starkweather adapted Xerox copier technology adding a laser
beam to it to come up with the laser printer. According to Xerox, "The Xerox 9700
Electronic Printing System, the first xerographic laser printer product, was
released in 1977. The 9700, a direct descendent from the original PARC "EARS"
printer which pioneered in laser scanning optics, character generation
electronics, and page-formatting software, was the first product on the market
to be enabled by PARC research."
• According to IBM, "the very first IBM 3800 was installed in the central accounting
office at F. W. Woolworth’s North American data center in Milwaukee,
Wisconsin in 1976." The IBM 3800 Printing System was the industry’s first high-
speed, laser printer. A laser printer that operated at speeds of more than 100
impressions-per-minute. It was the first printer to combine laser technology and
electrophotography according to IBM.
4. THE CHARACTERISTICS AND THE EXAMPLE OF
PRINTER
• Dot matrix printer uses iron plates, which create small
dot or square that join to make graphics and text. If
the machine produces 350 dots the quality will be
better.
• That has numbers and letters which can be raised and
arranged on a wheel that looks like aster.
• That can prints an images or character, using a small
snout that can spray ink on paper. The ink store to the
fifty chambers under the snout. These colors are
produced from the mixture of the four color.
• Use laser to change binary data to the printing result.
Can print many pages and all of the pages in a short
time.
