An ergonomic keyboard resembles a keyboard that has been split into half. This type of keyboard has its keys separated because it is specially designed to relieve sometimes painful conditions to the users that may have been resulted from overuse of keyboard. It has a 'split hands' design which is the main element that provides a more natural hand positioning while typing.
An ink-jet printer is the most commonly used type of consumer printers. This type of printer works by spraying ionized ink onto a sheet of paper. One thing good about this printer is that it is capable of producing high quality print almost compatible to those produced by laser printers. A typical ink-jet printer can provide a 300 dots per inch resolution.
A laser printer is different from an ink-jet printer in a way that the former applies a focused beam or light to transmit text and images onto a piece of paper. Due to the fact that laser printers are free from ink, they encounter less image smearing problems and hence able to print pages faster. Also, laser printers are sometimes known as page printers. Besides, they are also capable of producing high quality print as well as printing an almost unlimited variety of fonts.
MICR, short for magnetic-ink character reader, as a character recognition system that utilizes special ink and characters that can be magnetized and read automatically. It is more commonly used on bank checks and deposit slips. The function of MICR is to detect certain characters and then convert them into digital form. However, the problem with this recognition system is that it has its limitation in terms of the its accuracy.
Optical character recognition (OCR) is another recognition system whereby a software is used to convert non-editable letters and numbers into an editable form. It technically involves the reading process of texts from papers and then translating them into a form that the computers can understand. OCR is typically used in processing checks, archiving library materials and also sorting letters by postal offices.
OMR, the abbreviation for Optical-Mark Recognition is a form of technology that electronically extracts data from marked areas onto printed forms. It functions by scanning a printed form and reading areas that have been marked. It is especially useful when there is a large number of hand-filled forms that need to be processed in a short time frame with high accuracy.
