Image forming apparatus and control method thereof, and host apparatus usable with image forming apparatus and control method thereof

A control method of a host apparatus to be connected with the image forming apparatus through either of a local connection system or a network, the control method comprising:

• receiving network information of the image forming apparatus from the image forming apparatus if the image forming apparatus is connected through the local connection system;
• and
• transmitting printing data to the image forming apparatus on the basis of the received network information if the image forming apparatus is connected through the network.

An image forming system comprising:

• an image forming apparatus to generate network information and to print an image;
• and
• a host apparatus to receive the network information through a first communication line from the image forming apparatus, and to transmit printing data corresponding to the image to the image forming apparatus through a second communication line different from the first communication line.

The image forming system of claim 19, wherein the first communication line comprises a local communication line, and the second communication line comprises a network.

The image forming system of claim 20, wherein:

• the image forming apparatus comprises a first print communicating part and a second print communicating part;
• and
• the host apparatus comprises a first host communicating part connected to the first print communication part though the local communication line and a second host communicating part connected to the second print communicating part through the network.

The image forming system of claim 20, wherein:

• the image forming apparatus comprises a first print communicating part;
• and
• the host apparatus comprises a first host communicating part connected to the first print communicating part though the local communication line to transmit and receive the network information.

The image forming system of claim 22, wherein:

• the image forming apparatus comprises a second print communicating part;
• and
• the host apparatus comprises a second host communicating part connected to the second print communicating part though the network to transmit and receive the printing data.

A method of an image forming system, the method comprising:

• transmitting network information from an image forming apparatus to a host apparatus through a first communication line;
• and
• transmitting printing data from the host apparatus to the image forming apparatus through a second communication line different from the first communication line.
