Abstract: Disclosed is an image forming apparatus including a command receiving unit that receives a print command, a detector that detects a state of the operation unit, and a controller. When the detector detects that the state of the operation unit is a predetermined state subsequent to receiving the print command by the command receiving unit and prior to completion of printing based on the print command, the controller causes the printing to be terminated. When the detector detects that the state of the operation unit is not the predetermined state subsequent to receiving the print command by the command receiving unit and prior to the completion of the printing based on the print command, the controller causes the printing to be executed.

Abstract: A novel image forming apparatus that categorizes print job information for each newly added application and presents the print job information without categorizing data incorrectly and mixing in impersonation data. All of the applications that installed additionally extract jobs that went through itself only from trace information on jobs notified by the default functions and display it in a user interface. The trace information on jobs is a job ID association list that associates a job ID numbered by the default functions with a job ID of a job issued by the additional application.
