What are advantages if you send a fax from a fax machine?
The main advantages of sending a fax from a fax machine are that
you can have a single piece of equipment (the fax machine)
dedicated to sending and receiving faxes. You then have a
centralized record of what faxes were sent (usually just the date,
time, fax number, and number of pages) to check to see that an
attempted fax transmission was successful. You also do not have to
worry about compatibility issues, particularly around file types
for images sent over the Internet, since all fax machines can use
the same default protocol.
