Ergonomic Keyboard

This keyboard is designed to relieve some of the stress caused by typing due to the usage of fingers, hands and the wrists. It helps as it instills comfort to the users hands and wrists when they type. The "split hands" design is the central feature of the keyboard as it provides a more natural positioning for the hands to be more widely separated when typing. In conclusion, ergonomic keyboards provides a more natural position for typing and helps to reduce muscle stress on fingers, hands and wrists. This type of keyboard is also highly recommended by therapists and health care professionals.

Inkjet Printer

It is a type of printer that works by spraying ionized ink at a sheet of paper. Magnetized plates in the ink's path direct the ink onto the paper in the desired shapes. It is capable of producing high-quality prints. A typical inkjet printer offers a resolution of 300 dots per inch. Inkjet printers are also slower compared to laser printers and requires a special type of ink. The price of this type of printer is also cheaper compared to laser printers.

Laser Printer

It is a type of printer that works by using a focused beam or light to transfer texts and images onto paper. The printer works by having the paper pass through the printer then the laser beam fires at the surface of a cylindrical drum. This drum has an electrical charge (typically positive), that is reversed in areas where the laser beam hits it. By reversing the charge in certain areas of the drum, the laser beam can print patterns (such as text and pictures) onto the cylindrical drum. The pattern is then coated with toners. Laser printers has less image smearing problems because they do not use ink. Laser printers typically have a resolution of 600 dpi (dots per inch) or higher.

Magnetic-ink Character Recognition

Known also as MICR, it is primarily used by the bank industry. The technology allows computers to read information (such as account numbers) off printed documents and can be easily read by humans. MICR characters are printed in special typefaces with a magnetic ink or toner, usually containing iron oxide. The use of magnetic printing allows the characters to be read reliably even if they have been overprinted or obscured by other marks.

Optical-character Recognition

Abbreviated OCR, 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. OCR enables users to harness the power of computers to access printed documents.

Optical-mark Recognition

It electronically extracts intended data from marked fields, such as checkboxes and fill-infields, on printed forms. This technology is useful for applications in which large numbers of hand-filled forms need to be processed quickly and with great accuracy, such as surveys, reply cards and questionnaires. It is mostly used in schools for multiple-choice tests. The device scans the document and reads the data from the marked fields. The error rate for OMR technology is less than 1%.
