Ergonomic Keyboard
Ergonomic keyboard designs also help to relieve sometimes painful conditions such as Capra tunnel syndrome and repetitive stress injury that results from extended keyboard usage. These specially designed, contoured keyboards are created with comfort in mind, and are often recommended by therapists and health care professionals.The ergonomic keyboard was designed to to relieve some of that stress and provide a more comfortable platform for typing.
Inkjet Printer
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. Ink-jet printers are capable of producing high quality print approaching that produced by laser printers. A typical ink-jet printer provides are solution of 300 dots per inch although some newer models offer higher resolutions.
Laser Printer
A type of printer that utilizes a laser beam to produce an image on a drum. The light of the laser alters the electrical charge on the drum wherever it hits. The drum is then rolled through a reservoir of toner, which is picked up by the charged portions of the drum. Finally, the toner is transferred to the paper through a combination of heat and pressure. This is also the way copy machines work.
Magnetic-ink character recognition
In computing, a technique that enables special characters printed in magnetic ink to be read and input rapidly to a computer. MICR is used extensively in banking because magnetic-ink characters can be machine-read with much greater accuracy than human reading or Optical Character Recognition (OCR) systems, and are therefore ideal for marking and identifying the account and sort code numbers on cheques.
Optical character recognition
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 (for example, into ASCIIcodes). 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.
Optical mark recognition
Optical Mark Recognition (OMR) is the technology of electronically extracting intended data from marked fields, such as checkboxes and fill-in fields, on printed forms. It is generally distinguished from OCR by the fact that a recognition engine is not required. This requires the image to have high contrast and an easily-recognizable or irrelevant shape. OMR technology scans a printed form and reads predefined positions and records where marks are made on the form. 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, questionnaires and ballots.
