A facsimile can be transmitted via both the internet and the public network.
An
image is read from an original document, and image data is generated. The image
data is converted into facsimile data, and further corded into e-mail data. The
e-mail data is transmitted as a facsimile along with a header via the internet.
The header includes a title elected by a user. When a receiving party receives
the facsimile via the internet, the receiving party can obtain the general contents
of the facsimile and determine its urgency from the title.
