What device utilizes telephone lines to send messages and/or documents from one location to another?

The correct answer is a facsimile. A facsimile, commonly known as a fax machine, is specifically designed to transmit scanned printed material, such as documents and images, over telephone lines. It works by scanning the document into a digital format, converting it into a signal that can be transmitted over the phone line, and then reconstructing that signal on the receiving end back into a printed copy.

In contrast, a scanner is a device that captures images and documents for digital storage but does not transmit them. A printer produces hard copies of digital documents but does not send or receive messages over telephone lines. Photography refers to the art or practice of creating images by recording light, usually via a digital or chemical process, and does not involve the transmission of documents at all. Hence, the facsimile is the only device specifically designed for the purpose of sending documents via telephone lines.
