I sent my first fax in the mid-1990s. Today many people scan documents into their computers and send them as PDF files or as E-mail attachments. Or, if they want to fax they can do it using the fax function on a copier machine much faster than the 1990s-era machines which were telephones equipped with a tray into which paper was inserted. When I sent my first fax I was an adult, but it was a novelty to me and I didn’t really understand it. What I did was copy my document: one for me to keep and one to fax. LOL.
