Embedded fax server device

The invention discloses an embedded fax server device. The device comprises a microprocessor control circuit, a network connection device and a PSTN connection device, wherein the network connection device is used to access the fax server device in a network; the PSTN connection device is used to connect the fax server device with a fax; and the microprocessor control circuit is used to receive the network content transmitted by the network connection device and convert the network content to the fax content which can be identified by the fax, or receive the fax content which is sent by the fax through the PSTN connection device and convert the fax content to the network content. The embedded fax server provided by the invention can be accessed in the network and connected with the fax; by detecting the address of the content to be faxed by the user, the content to be faxed by the user is sent to a target device directly or through the conversion of the content format, thus the fax can send content to the network and the network content can be sent to the fax. Therefore, the network-based receiving and sending process of faxes can be realized.
