As with digital photocopiers and multifunction printers, laser printers employ a xerographic printing process but differ from analog photocopiers in that the image is produced by the direct scanning of a laser beam across the printer's photoreceptor.


Magnetic-ink Character Reader (MICR)

Magnetic Ink Character Recognition, or 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, MICR codes can be easily read by humans.


Optical-character Recognition (OCR)

Optical character recognition, or OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine-encoded text. It is widely used to convert books and documents into electronic files, to computerize a record-keeping system in an office, or to publish the text on a website.


Optical-mark Recognition (OMR)

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