An image forming apparatus includes a scanner unit configured to read an original document, a memory unit configured to store image data, a printer unit configured to print image data, and an analysis unit configured to analyze a print specification sheet read by the scanner, wherein when the analysis unit determines that in a first print specification sheet there is no instruction to read a second print specification sheet, the printer unit prints image data based on the first print specification sheet, and when the analysis unit determines that in the first specification sheet there is an instruction to read a second print specification sheet, the printer unit prints image data specified on the first and second print specification sheets based on the first or the second print specification sheet.

Claims

1. An image forming apparatus comprising:

a scanner unit configured to read an original document;

a memory unit configured to store image data;

a printer unit configured to print image data; and

an analysis unit configured to analyze a print specification sheet read by the scanner, wherein when the analysis unit determines that in a first print specification sheet there is no instruction to read a second print specification sheet, the printer unit prints image data based on the first print specification sheet, and when the analysis unit determines that in the first specification sheet there is an instruction to read a second print specification sheet, the printer unit prints image data specified on the first and second print specification sheets based on the first or the second print specification sheet.

2. The image forming apparatus according to claim 1, wherein the scanner unit reads the second print specification sheet based on an analysis result by the analysis unit concerning at least one of a marked item instructing to read a print instruction on the second specification sheet described in the first print specification sheet, and a marked item instructing to read image data on the second print specification sheet.

3. The image forming apparatus according to claim 1, wherein the printer prints the image data according to a print instruction on the second print specification sheet giving priority to a print instruction on the second print specification sheet when an instruction to print the image data is specified by the second print specification sheet, and the printer prints the image data according to a print instruction on the first print specification sheet giving priority to a print instruction on the first print specification sheet when an instruction to print the image data is not specified on the second print specification sheet.

4. The image forming apparatus according to claim 1, wherein the scanner reads the second print specification sheet when the analysis unit determines that in the first print specification sheet there is an instruction to read the second print specification sheet, even if there are instructions as to the same image in the first print specification sheet and the second print specification sheet.

5. The image forming apparatus according to claim 1, wherein the scanner unit reads print specification sheets until an analysis result by the analysis unit indicates that there is no instruction to read the next print specification sheet.

6. A method for controlling an image forming apparatus having a scanner configured to read an original document, a memory unit configured to store image data, and a printer unit configured to print image data, the method comprising:

analyzing a first print specification sheet;

printing image data based on a first print specification sheet, if an analysis result indicates that in the first print specification sheet there is no instruction to read a second print specification sheet; and

printing image data specified by the first and the second print specification sheets based on the first or the second print specification sheet, if the analysis result indicates that in the first print specification sheet there is an instruction to read the second specification sheet.

7. A method for controlling the image forming apparatus according to claim 6, wherein reading the second print specification sheet the scanner unit based on an analysis result by the analysis unit concerning at least one of a marked item instructing to read a print instruction on the second specification sheet described in the first print specification sheet, and a marked item instructing to read image data on the second print specification sheet.

8. A method for controlling the image forming apparatus according to claim 6, wherein printing the image data by the printer unit according to a print instruction on the second print specification sheet giving priority to a print instruction on the second print specification sheet when an instruction to print the image data is specified by the second print specification sheet, and the printer prints the image data according to a print instruction on the first print specification sheet giving priority to a print instruction on the first print specification sheet when an instruction to print the image data is not specified on the second print specification sheet.

9. A method for controlling the image forming apparatus according to claim 6, wherein reading the second print specification sheet by the scanner unit when the analysis result indicates that in the first print specification sheet there is an instruction to read the second print specification sheet, even if there are instructions as to the same image in the first print specification sheet and the second print specification sheet.

10. A method for controlling the image forming apparatus according to claim 6, wherein reading print specification sheets by the scanner unit until an analysis result indicates that there is no instruction to read the next print specification sheet.
