There are two ways:

1) print the fax out, then fax it

2) sign up for an online fax service that will let you send a fax through email - this will let you send the fax as an email, just by entering the fax number in the same as if it was an email address.

Sure, when I have to.

To send a fax from the UK to a +1 number, you would need to dial:

00-1-number

00 is the code to dial internationally, 1 is the country code for the USA or Canada (as well as some other nations in the Carribbean).

The "1" in that code replaces the +1 in the number you have.

There is also the ability to send a fax via web, so you don't need a fax machine.

To fax from Australia to Boston you would need to dial:

0011-1-fax number

0011 is to dial internationally from Australia.

1 is the international country code for the United States.

The fax number should be 10 digits.

To fax from Mexico to the United States you need to dial:

00 + 1 + fax number (including area code)
