Image forming apparatus and method of forming image thereof

An image forming apparatus connectable to a print controlling terminal, comprising:

• a communication interface unit which allows the print controlling terminal to recognize the image forming apparatus as a printer if the image forming apparatus is connected to the print controlling terminal;
• a determination unit which determines whether a printer driver of the image forming apparatus is installed in the print controlling terminal;
• a controlling unit which, if a printer driver is installed in the print controlling terminal, controls the communication interface unit to receive print data generated by the printer driver;
• and
• an image forming unit which prints the received print data,
• wherein the communication interface unit, if a printer driver is not installed in the print controlling terminal, controls the print controlling terminal to additionally recognize the image forming apparatus as an external storage medium and provides the print controlling terminal with a printer driver installation program stored in the external storage medium.
