Selecting Fax Sender from the Chooser
If you do not have a printer, or if you plan on sending faxes
often, you can make Fax Sender the selected output device
for all your documents, just as you normally select a printer.
When Fax Sender is the selected output device, each time
you print from a program or from the system your document
is sent as a fax instead.
To make Fax Sender the selected output device
1 Open the Chooser from the Apple (K) menu.
The Chooser appears.
2 Select the Fax Sender icon from the upper left panel.
3 Close the Chooser.
Fax Sender remains selected until you choose another
device in the Chooser.
