If you don’t have access to a fax machine, but need to send a quick document, try FaxZero.
This web site lets you send a fax from your computer. Use a Word .doc or a .pdf. You can also type the text that appears on the cover page. Just upload the file and click Send.
They allow five faxes per day, with a maximum of three pages each. The drawback is your recipient will see an ad on the cover page, but if you like the service, there is a paid, no-ad version.
