Is faxing instant? How does it work exactly?

Answer 1

It's not instant, but it is pretty fast. It's basically two computer modems talking to eachother over a phone line.

The sending fax uses a camera of sorts to scan the document to be sent, and encodes it digitally. The digital information is sent over the phone line to the receiveing fax, where the receiving fax basically prints it.

Answer 2

A fax machine is essentially an image scanner, a modem, and a computer printer combined into a highly specialized package. The scanner converts the content of a physical document into a digital image, the modem sends the image data over a phone line, and the printer at the other end makes a duplicate of the original document.

Fax machines with additional electronic features can connect to computers, can be used to scan documents into a computer, and to print documents from the computer. Such high-end devices are called multifunction printers and cost more than fax machines.

Answer 3

A fascimile? It is instant more or less. Once it scans your paper, it converts it to data (ones and zeros), and than calls the other fax over the phoneline. The other fax in turn takes the ones and zeros, and converts it back to an image, and prints it onto paper.
