An outbound fax transmission includes the following elements:
A document file. The fax service converts the data to the Tagged Image File Format Class F (TIFF Class F) for facsimile. For more information, see Fax Image Format.
Transmission information. Information includes the fax number, sender and recipient data, an optional billing code, and job scheduling information. In the Microsoft Win32 environment, if the application is printing to a device context, a FAX_PRINT_INFO structure contains this information. In other instances, a FAX_JOB_PARAM structure contains this information.
If you are using the Microsoft Component Object Model (COM) implementation, you can set multiple properties of the IFaxJob object to specify transmission information. For more information, see Transmitting Faxes.
An optional cover page file. In the Win32 environment, the FAX_COVERPAGE_INFO structure contains this data. The structure supplies the name of a cover page template file (.cov) and user-defined information for the template.
If you are using the Microsoft COM implementation, you can set multiple properties of the FaxDoc object to specify cover page information. For more information, see Cover Pages and Sending a Cover Page.
