An image-forming device is configured so that a process to print confidential print data is not automatically resumed after the printing process has been interrupted and the cause of the interruption has been resolved. Accordingly, the printing of confidential print data is not resumed when the user who requested the printing operation is not near the printer during an interruption and another person resolves the cause of the interruption. In this way the image-forming device prevents content of the confidential print data from being exposed to another person.
