You send faxes by selecting the respective fax (printer) driver in the print process. A fax program must be installed in order to be able to send faxes.
If the fax is to be sent via the Windows fax driver, the fax parameters (at least the fax number) must be specified in the project properties. Enter the respective variables in the "Fax Parameters" area.
If the fax is to be sent via a different fax (printer) driver, you enter the fax number and other field information (as far as supported) by means of commands (e.g. DvISE commands for Tobit David). You enter these commands directly in a text field in the print project. Doing this suppresses the recipient dialog during printing because all information is already embedded in the document. You will find the precise procedure in the documentation for your fax software.
You can also send directly by email. You also define the required email variables in the project's property window. The mail settings (SMTP, MAPI, XMAPI) can be configured in the application.
