Input and output magnetic link character

recognition:(MICR)
MICR is a character recognition technology used primarily by the banking industry to facilitate the processing of cheques. The technology allows computers to read information (such as account numbers) off of printed documents. Unlike barcodes or similar technologies, however, MICR codes can be easily read by humans.MICR characters are printed in special typefaces with a magnetic ink or toner, usually containing iron oxide. As a machine decodes the MICR text, it first magnetizes the characters in the plane of the paper. Then the characters are then passed over a MICR read head, a device similar to the playback head of a tape recorder. As each character passes over the head it produces a unique waveform that can be easily identified by the system.
Optical character:(OCR)
Optical character is the mechanical or electronic translation of images of handwritten, typewritten or printed text into machine text.OCR is a field of research in pattern recognition, artificial intelligence and computer vision. Though academic research in the field continues, the focus on OCR has shifted to implementation of proven techniques. Optical character recognition and digital character recognition were originally considered separate fields. Because very few applications survive that use true optical techniques, the OCR term has now been broadened to include digital image processing as well.
Optical mark recognition:(OMR)
Often abbreviated OCR, optical character recognition refers to the branch of computer science that involves reading text from paper and translating the images into a form that the computer can manipulate. An OCR system enables you to take a book or a magazine article, feed it directly into an electronic computer file, and then edit the file using a word processor. All OCR systems include an optical scanner for reading text, and sophisticated software for analyzing images. Most OCR systems use a combination of hardware and software to recognize characters, although some inexpensive systems do it entirely through software.
Dot matrix printer:

A dot matrix printer or impact matrix printer is a type of computer printer with a print head that runs back and forth, or in an up and down motion, on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper, much like a typewriter. Unlike a typewriter or daisy wheel printer, letters are drawn out of a dot matrix, and thus, varied fonts and arbitrary graphics can be produced. Because the printing involves mechanical pressure, these printers can create carbon copies and carbonless copies.
Plotter:
plotter is a device that draws pictures on paper based on commands from a computer. Plotters differ from printers in that they draw lines using a pen. As a result, they can produce continuous lines, whereas printers can only simulate lines by printing a closely spaced series of dots. Multicolor plotters use different-colored pens to draw different colors.
In general, plotters are considerably more expensive than printers. They are used in engineering applications where precision is mandatory.

PHoto printer:

printers currently sold to home users are marketed as "photo printers" because there are no official specifications designating what is and isn't a photo printer. Not all these models print photos as well as dedicated photo printers can, so some see this as a marketing ploy to increase the appeal of the product to the consumer.

Portable printer:
portable printers provide workers with the ability to print documents while on the road. Usingportable printers can save time and allow you to be more productive. Find out what different portable printers offer and which mobile printers is best for your needs.

Fax machine:
Fax is a telecommunications technology used to transfer copies of documents, especially using affordable devices operating over the telephone network. The word telefax, short for telefacsimile, for "make a copy at a distance", is also used as a synonym. Although fax is not an acronym (as it is abbreviated from facsimile), it is often written as “FAX”. The device is also known as a telecopier in certain industries.

Multifunctional device:
Multifunctional devices bring the worlds of copying, printing, finishing, and scanning together, all in one neat, efficient and cost-effective package. Uniquely, Officemagic has excellent deals on mutifunctional devices specially selected, cutting-edge colour enabled systems.

INternet telephones:
Internet telephones is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband , broadband telephony, and broadband phone.
Internet telephony refers to communications services. The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol packets for transmission over the Interne.
