Magnetic Ink Character Recognition.

Magnetic Ink Character Recognition - (MICR) A character recognition system using special ink and characters which can be magnetised and read automatically.MICR is used almost exclusively in the banking industry where it is used to print details on cheques to enable automatic processing.

Optical Character Recognition.

This is the technology long used by libraries and government agencies to make lengthy documents quickly available electronically. Advances in OCR technology have spurred its increasing use by enterprises. For many document-input tasks, OCR is the most cost-effective and speedy method available. And each year, the technology frees acres of storage space once given over to file cabinets and boxes full of paper documents.

Optical Mark Recognition.

Optical Mark Recognition (also called Optical Mark Reading and OMR) is the process of capturing human-marked data from document forms such as surveys and tests.

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.

Plotters

A plotter is a vector graphics printing device to print graphical plots, that connects to a computer. There are two types of main plotters. Those are pen plotters and electrostatic plotters.

Photo printer

A photo printer is a printer (usually an inkjet printer) that is specifically designed to print high quality digital photos on photo paper. These printers usually have a very high number of nozzles and are capable of printing droplets as small as 1 picoliter.

Portable printer

For people that are travelling but who need to work while on the go, a small portable printer that is light weight and easy to carry can be a necessity. So far the producers of laptops haven’t been able to incorporate a printer into the computer itself but it will very likely be something that will happen in the near future. But until that happens, we’ll have to find a printer that is small, weighs very little but that will still be able to print in high quality and at a reasonable speed.

Fax machine

is a telecommunications technology used to transfer copies (facsimiles) of documents, especially using affordable devices operating over the telephone network.

Multifunctional devices

putting a printer, scanner, copier and sometimes even a fax machine all in a single case, the price for the combination unit is less than the total cost for the individual units would be. What's more, the all-rounders require less space and even work without a computer in fax (if available) and copy modes.

Internet telephones

Internet Telephone allows you to make calls from your PC over the internet to anywhere in the World at highly competitive rates.

Telephony

In telecommunication, telephony encompasses the general use of equipment to provide voice communication over distances, specifically by connecting telephones to each other.
