The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An image forming apparatus, comprising:
a storage unit configured to store job data transmitted from an information processing apparatus;
a display unit configured to display information of the job data stored in the storage unit when an execution instruction for executing the job data is received in response to a user operation; and
a deletion unit configured to determine whether the display unit displays the information of the job data, and to suspend deletion processing for deleting the job data from the storage unit in a case where the deletion unit determines that the display unit displays the information of the job data, whereas to delete the job data from the storage unit in a case where the deletion unit determines that the display unit displays no information of the job data.
2. The image forming apparatus according to claim 1, wherein, in a case where the deletion unit determines that a size of a storage area for storing the job data is smaller than a predetermined size and that the display unit displays no information of the job data, the deletion unit continues to delete the job data stored in the storage unit until the predetermined size is secured.
3. The image forming apparatus according to claim 1, wherein the job data stored in the storage unit is a print job data and the display unit displays the information of the job data stored in the storage unit as a candidate to be reprinted.
4. The image forming apparatus according to claim 1, wherein the deletion unit deletes a job data sequentially from the job data having older execution time information indicating when the job data is executed in the job data stored in the storage unit.
5. The image forming apparatus according to claim 1, wherein the deletion unit deletes sequentially from a job data having older storage time information indicating when the job data is stored in the storage unit in the job data stored in the storage unit.
6. The image forming apparatus according to claim 1, further comprising:
a receiving buffer configured to store job data transmitted from the information processing apparatus,
wherein the storage unit stores the job data transferred from the receiving buffer; and
wherein, in a case where the display unit displays the information of the job data, the deletion processing for deleting the job data from the storage unit is suspended by stopping the transfer of the job data from the receiving buffer to the storage unit.
7. A job management method in an image forming apparatus, comprising:
storing job data transmitted from an information processing apparatus in a storage unit;
displaying information of the job data stored in the storage unit on a display unit upon receiving an execution instruction for executing the job data in response to a user operation; and
deleting the job data from the storage unit, wherein it is determined whether the display unit displays the information of the job data and deletion processing for deleting the job data from the storage unit is suspended in a case where a determination is made that the display unit displays the information of the job data, whereas the job data is deleted from the storage unit in a case where a determination is made that the display unit displays no information of the job data.
8. A computer-readable storage medium storing a control program for causing a computer to perform operations comprising:
storing job data transmitted from an information processing apparatus in a storage unit;
displaying information of the job data stored in the storage unit on a display unit upon receiving an execution instruction for executing the job data in response to a user operation; and
