What are different Types of Printers? Impact Printers and Non Impact Printers in Detail...

Printer Types: Impact & Non-Impact Printers

Printers

A printer is an output device that prints characters, symbols and graphics on paper. The printed output is called hard copy. Printers produce permanent documents. Print resolution is commonly measured in dots per inch (dpi). A printer with higher print resolution, that is, dpi will produce higher quality print outs, but it will cost higher too.

Types of Printers

Depending upon the mechanism of printing, there different types of printers, as follows:

1) Impact Printers

2) Non-Impact Printers

1. Impact Printers

An impact printer works like a typewriter. It prints characters or images by striking a print hammer , a typeface or pins against paper and inked ribbon. We can say that impact printers do hit or impact an inked ribbon to print on a paper. Since, impact printers produce print outs by striking mechanism, they make a lot of noise, too. Print quality of impact printers is lower than print quality of non-impact printers. Printing cost or impact printers is lower than that of non-impact printers.

Types of Impact Printers

Dot Matrix Printer

A dot matrix printer is an impact printer. It produces printed images when tiny pins on a print head strike an inked ribbon. When the ribbon presses against the paper, it creates dots that form characters and graphics. The print head on a dot matrix printer can contain nine to twenty-four pins. Dot matrix printers use 100 to 300 DPI(dots per inch). Their speed is from 200 to 1000 characters per minute. Dot matrix printers generate a lot of noise. They do not produce a very high quality of print.

Drum Printer

Drum printer is an impact printer. It consists of a solid and cylindrical drum. The drum  has raised characters in bands on its surface. The drum rotates rapidly. For each print position, there is a print hammer to strike on ribbon and paper. The drum prints one line in one rotation. Since drum printer prints one line at a time, so it is called a line printer. Drum printer is a fast impact printer. It prints an entire line at a time. Its speed is measured in lines per minute (1pm). Many drum printers can print up to 2000 lines per minute.

Daisy Wheel Printer

Daisy wheel printer is similar to a typewriter. It uses a print wheel. The print wheel is called daisy wheel. Each petal of daisy wheel contains character. A motor rotates the wheel. A hammer strikes a petal against the ribbon when the desired character reaches the position on the paper. This prints the character on the paper. Daisy wheel printer is slower than dot matrix printer but better in quality. Daisy wheel technology is now found only in some electronic typewriters.Now-a-days mostly laser printers or ink jet printers are used.

2. Non-Impact Printers

A non-impact printer prints characters and graphics on a piece of paper without striking the paper. Some of these printers use spray ink while others use heat and pressure to create images. These printers are faster than impact printer. We can say that non-impact printers do not hit or impact an inked ribbon to print on a paper. Since, impact printers produce print outs by non-striking mechanism, they do not make a noise, Print quality of non-impact printers is higher than print quality of impact printers. Printing cost of non-impact printers is higher than that of impact printers.

Types of Non-Impact Printers

Laser Printer

Laser printers are non-impact printers. The laser printer creates image on the paper by the laser beam. LASER stands for Light Amplification by Stimulated Emission of Radiation. Laser throws magnetic material powder on paper in the form of microscopic dots. The density of these dots ranges from 300 to 2000 Dots per Inch (DPI). The printing speed of laser printers is from 5 to 300 pages per minute (ppm). Laser

printers are also called page printers. They print complete page at a time. Laser printers produce very high quality print. They are faster than inkjet and dot matrix printers. Color printing with laser printers is Very costly. Laser printers are mostly used in business field.

Ink-jet Printer

It is a non-impact printer. It prints text and graphics by spraying tiny drops of liquid ink on paper. These printers can produce quality text and graphics in black and white and color. Ink jet printers are slower than laser printer. They can print 1 to 6 pages per minute. Ink-jet printers are relatively inexpensive than laser printer.

8	It produces less sharp  output than LCD monitors.	LCD monitors produce sharper and clear output.

Different Types of Monitors

Monitor

Monitor is the most familiar output device. It is a display screen or visual display unit to show text and graphics to computer user. Common monitors look like a TV. Latest monitors are flat panel monitors like LCD monitors. Although LCD monitors are more costly than general old fashioned monitors called CRT monitors, they are light weight and don't emit radiations harmful to eyes.

Types of Monitors

There are the following main types of Monitors:

1. CRT Monitors

2. Flat Panel Monitors

3. Touch Screen Monitors

1. CRT Monitors

CRT stands for Cathode Ray Tube. CRT monitors use electronic beam gun to produce text and images. These electronic guns fire a beam of electrons on very tiny phosphorus dots on internal surface of screen. In color CRT monitors there are three electron beam guns for Red, Green and Blue colors. CRT monitors take more space on desk.

These are heavier than flat panel monitors. CRT monitors emit radiations which are harmful for human eyes. CRT monitors are less costly.

2. Flat Panel Monitors

 Flat panel monitors are thin, light weight and more compact and portable. Flat panel monitors take less space on desktop. Flat panel monitors do not emit harmful radiations. They consume less power than CRT monitors. They produce higher quality results than RCT monitors. Flat panel monitors are more costly than CRT monitors.

3. Touch Screen Monitors

Touch Screen Monitor is an input/output device. It uses a special touch sensitive screen. The User can enter data by touching icons or menus on the screen. As soon as the user selects a command from menu, output is displayed on screen. Commonly touch screen monitors use sensors to detect touch of finger.
Touch screen monitors are special input / output devices. Since they perform both functions that is, input and output at the same time, they are called dual devices or dual purpose devices or both input/output devices. ATM machines outside banks are one of the common examples of touch screen monitors.

What are Different Types of e-Payment Security Protocols

What are different security protocols for e-payment security schemes?

1. SSL Protocol (Secure Sockets Layer Protocol)

SSL (Secure Sockets Layer) is the standard security protocol for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is used by millions of websites in the protection of their online transactions with their customers.
SSL or Secure Sockets Layer is a security protocol created by Netscape that has become an international standard on the Internet for exchanging sensitive information between a website and the client computer. SSL technology is embedded in all popular browsers and engages automatically when the user connects to a web server that is SSL-enabled. It's easy to tell when a server is using SSL security because the address in the URL window of your browser will start with https. The "s" indicates a secure connection.

2. SET ( Secure Electronic Transaction Protocol)

SET was initially designed by Visa and Master Card in 1997. Secure Electronic Transaction (SET) is a standard protocol for securing credit card transactions over the Internet.
To meet the business requirements, SET incorporates the following features:

* Confidentiality of information

* Integrity of data

* Cardholder account authentication

* Merchant authentication

In SET protocol there are four entities: cardholder, merchant, CA (certificate authority)and payment gateway. A certificate authority or certification authority (CA) is an entity that issues digital certificates. The role of a payment gateway is to connect the internet and the proprietary networks of banks. Each participation entity needs its own certificate. Electronic Wallet or e-wallet or digital wallet is software used to store certificate consumer’s personal computer.
