A printing control terminal device connectable to an image forming apparatus having a resource saving mode, comprising: an input unit configured to receive a user input in an executed application; and a display unit configured to display, in response to a user input in the executed application, a printing window to allow a user to set at least one printing option to be applied to a printing work through the executed application; wherein in response to receiving, through the input unit, a printing order to request a printing operation for the printing work and the at least one printing option to be applied to the printing work; a communication interface unit of the printing control terminal device is configured to receive information regarding a resource saving mode from the image forming apparatus; and the display unit is configured to display the received information regarding the resource saving mode, wherein the displaying comprises displaying, in the form of a pop-up window, a user interface window (300,400) including a first area (310,410) to display whether the image forming apparatus is operating in the resource saving mode, a second area (320,420) to display information of the printing options applied in the resource saving mode, and a third area to display property values corresponding to the printing options applied in the resource saving mode; wherein in response to receiving an input from the user to change at least one property value of the printing options applied in the resource saving mode: a printer driver unit of the printing control terminal device is configured to generate printing data for the printing work according to the printing options applied when the image forming apparatus is operating in the resource saving mode and the at least one property value set by the user through the third area; and a controller of the printing control terminal device is configured to control the communication interface unit to transmit the generated printing data to the image forming apparatus, wherein the display unit is configured, if a user sets the image forming apparatus to operate in the resource saving mode during the process of setting the at least one printing option, to not display the received information regarding the resource saving mode. an input unit configured to receive a user input in an executed application; and a display unit configured to display, in response to a user input in the executed application, a printing window to allow a user to set at least one printing option to be applied to a printing work through the executed application;
