Image forming device

A method of executing a reprinting operation for an image forming device provided with an internal storage, an external storage being detachably connectable to the image forming device, a display unit, and a printing unit configured to print an image on a recording sheet based on image data developed from print data which is retrieved from the external storage or transmitted from an external device, comprising the steps of:

• storing the image data developed from the print data, which is retrieved from in the external storage, in the external storage;
• storing the image data developed from the print data, which is transmitted from the external device, in the internal storage;
• selectably displaying at least file names of image data stored in the external storage on the displaying unit when the external storage is connected to the image forming device;
• selectably displaying file names of image data stored in the internal storage on the displaying unit when the external storage is not connected to the image forming device;
• and
• executing the reprinting operation based on the selected image data.

A non-transitory computer accessible medium comprising computer readable instructions stored thereon, which when executed by a computer, cause an image forming device provided with an internal storage, an external storage which is detachably connectable to the image forming device, a display unit, and a printing unit configured to print an image on a recording sheet based on image data developed from print data which is retrieved from the external storage or transmitted from an external device to execute the steps of:

• storing the image data developed from the print data, which is retrieved from the external storage, in the external storage;
• storing the image data developed from the print data, which is transmitted from the external device, in the internal storage;
• selectably displaying at least file names of image data stored in the external storage on the displaying unit when the external storage is connected to the image forming device;
• selectably displaying file names of image data stored in the internal storage on the displaying unit when the external storage is not connected to the image forming device;
• and
• executing the reprinting operation based on the selected image data.
