A print control method of an image forming apparatus is provided to display all the supportable color print modes in a printer driver user interface if all the colors of toner are sufficient, and to check print modes in which normal print quality can not obtained and to restrict the corresponding print modes if one and more colors of toner are insufficient. A print control method of an image forming apparatus comprises the following several steps. A controller measures remaining amounts of yellow, magenta and cyan colors of toner(S100). The controller checks whether the remaining amounts of one and more colors are insufficient compared with reference amounts required for color print(S101). The controller determines that a color print mode can not be set if the remaining amounts of one and more colors are insufficient(S102). The controller measures a remaining amount of a black color(S103). The controller checks whether the remaining amount of the black color is insufficient compared with a reference amount required for mono color print(S104). The controller determines that a mono print mode can not be set if the remaining amount of the block color is insufficient(S106). Then, the controller performs a control operation for restricting a user to select the color or the mono print mode(S107). If the remaining amount of the black color is sufficient, the controller performs a control operation for restricting the user to select the color print mode and allowing the user to select the mono print mode(S105).
