An image processing apparatus comprising: a receiving section which receives a print job created by a printer driver in a terminal apparatus; a storage section which stores the print job received by the receiving section; a printer section which carries out printing related to the print job received by the receiving section; a change receiving section which receives an instruction of change in a content of setting of the print job stored in the storage section; a change processing section which creates a print job by changing the content of setting of the print job stored in the storage section based on the instruction of change received by the change receiving section; a change requesting section which informs the printer driver about content of the instruction of change received by the change receiving section, and allows the printer driver to create a print job by changing the content of setting of the print job based on the instruction of change; and a control section which selects whether to allow the change processing section or the change requesting section to handle the instruction of change received by the change receiving section, and allows a selected section to handle the instruction of change, characterized in that the image processing apparatus is configured such that the control section confirms a start-up state of the printer driver when the control section selects the change requesting section, and if the printer driver has not started as a result of the confirmation, the control section starts the printer driver, wherein if the control section cannot confirm that the printer driver has started as a result of the confirmation, the control section carries out control so that the change processing section creates a print job by changing the content of setting of the print job stored in the storage section based on only instruction of change among one or more instructions of change which have been received by the change receiving section, the only instruction of change having been selected to be handled by the change processing section. a receiving section which receives a print job created by a printer driver in a terminal apparatus; a storage section which stores the print job received by the receiving section; a printer section which carries out printing related to the print job received by the receiving section; a change receiving section which receives an instruction of change in a content of setting of the print job stored in the storage section; a change processing section which creates a print job by changing the content of setting of the print job stored in the storage section based on the instruction of change received by the change receiving section; a change requesting section which informs the printer driver about content of the instruction of change received by the change receiving section, and allows the printer driver to create a print job by changing the content of setting of the print job based on the instruction of change; and a control section which selects whether to allow the change processing section or the change requesting section to handle the instruction of change received by the change receiving section, and allows a selected section to handle the instruction of change, characterized in that the image processing apparatus is configured such that the control section confirms a start-up state of the printer driver when the control section selects the change requesting section, and if the printer driver has not started as a result of the confirmation, the control section starts the printer driver, wherein if the control section cannot confirm that the printer driver has started as a result of the confirmation, the control section carries out control so that the change processing section creates a print job by changing the content of setting of the print job stored in the storage section based on only instruction of change among one or more instructions of change which have been received by the change receiving section, the only instruction of change having been selected to be handled by the change processing section.
