fax machine

A fax machine is a device that transfers scanned printed documents electronically over a telephone line. It converts the paper document into a digital image, transmits it to another fax machine, which then reproduces the document onto paper. This process allows for quick sharing of physical documents without scanning or emailing. Although less common today, fax machines are still used in some industries for secure or official document transmission. Think of it as a way to send a paper copy across distances instantly, combining printing and telephony to facilitate document exchange.
