In the olden days (like up to 15 years ago) if you wanted to send someone a copy of a document you would fax it.

It’s essentially a dial up image transfer. The fax machine at one end scans the image, connects via a phone call to the fax machine at the other end, transmits the data across the phone line for the documents image and then the receiving fax machine prints it.

Obviously, email is quicker and easier and fax machines have mostly fallen out of use.
