METHOD OF CONTROLLING SPEED OF ETHERNET CONNECTION IN POWER SAVE MODE AND IMAGE FORMING APPARATUS PERFORMING THE SAME

摘要

A method of controlling a speed of an Ethernet connection in a power-save mode of an image forming apparatus includes turning off a print engine when the image forming apparatus enters the power save mode, reducing the speed of the Ethernet connection between the image forming apparatus and an external device, detecting an attempt to transmit printing data via the Ethernet connection from the external device, determining a necessity of increasing the speed of the Ethernet connection based on the printing data, and receiving and outputting the printing data, wherein the receiving and outputting the printing data comprises, when it is not necessary to increase the speed of the Ethernet connection as a result of the determining, receiving and outputting the printing data after turning on the print engine, without changing the speed of the Ethernet connection.
