Method for transmitting several format document in multi function peripheral}

The present invention relates to a document transmission method of various formats in a multifunction printer, and more particularly, a multifunction device for transmitting a document written in a computer connected to the multifunction device after transmitting a fax document according to the T.30 protocol in the multifunction device. The present invention relates to a document transmission method of various formats in.

In general, a multifunction device refers to a device that performs not only a function of a printer for printing data or an original input from a computer, but also a function of a facsimile for transmitting an image document to another place through a communication line. In other words, the multifunction device is a multi-function terminal made by weaving existing terminal devices such as a facsimile and a printer into one, and refers to a device having a PC-interface function, which is a function of interworking with a PC.

In order to perform a function as a facsimile among the functions of the multifunction apparatus, a fax modem should be provided, and a method of transmitting a document to a predetermined counterpart in a multifunction apparatus equipped with a fax modem will be described below.

First, a document to be transmitted to the other party is set, and then a phone number of a predetermined party is input. When the telephone line and the inputted telephone line are established, the sender exchanges the protocol with the receiving fax.

Here, the protocol defines a procedure of exchanging control information between terminal devices that transmit / receive predetermined data using a data transmission network like a facsimile. Examples include call selection, call release procedures, and data flow control.

The general facsimile is the difference in capability between the sending and receiving facsimile (scanning time, coding / decoding time, printing time, etc.) while sending and receiving control information in accordance with the protocol regulations recommended in Regulation T.30 of CCITT. ).

When this adjustment is completed, the set original is scanned, and the scanned data (hereinafter referred to as 'fax data') is transferred to a PSTN (public switched telephone network) by means of transmission such as a modem and a Line Interface Unit (LIU). It transmits to the receiver through Public Switched Telephone Network.

On the other hand, the receiving side facsimile stores the fax data received from the sending side facsimile in a memory or prints it through a printer.

In such a multifunction device, a fax modem provided for transmitting fax data to a remote fax may transmit not only the fax data but also data created by an application program of a computer (hereinafter, referred to as binary data).

On the other hand, due to the recent rapid development of the Internet, e-mail (hereinafter referred to as 'E-Mail') is being actively used, and E-mail is a text data or binary to a predetermined counterpart through a modem or a local area network (LAN). Data can be transmitted, and in this case, one document can be transmitted to several counterparts, and various documents can be attached to one counterpart.

Here, in an E-mail that transmits text data or binary data to the other party using a modem, a modem protocol (eg, Z-modem, K-modem, Kermit, X-modem, Y-modem, etc.) is exchanged with the receiving side. After that, the data is transmitted.

However, since the facsimile function of the multifunction device does not have a function of attaching various documents and sending them to the other party, the use of facsimile gradually decreases, while the use of e-mail is increasing.

That is, although the fax modem provided with the multifunction apparatus can transmit not only the fax data but also the binary data, it causes inconvenience in use because only the fax data is transmitted by the T.30 protocol.

Accordingly, an object of the present invention is to solve such a problem, and an object of the present invention is to convert a protocol so that binary data created by an application program of a computer connected to the multifunction device can be attached when a fax data is transmitted from a multifunction device facsimile. The present invention provides a method for transmitting documents in various formats in an all-in-one that can replace an e-mail in which a speed difference occurs depending on the speed of the network.
