Abstract
An image forming apparatus obtains first print data from an external apparatus, stores, in a storage, identification information representing that image formation based on the first print data is uncompleted, obtains second print data from the external apparatus in a status in which the identification information is not stored in the storage, and inhibits obtaining of the second print data from the external apparatus in a status in which the identification information is stored in the storage.
Claims12
An image forming apparatus capable of communicating with an external apparatus, comprising:
- a storage configured to store information;
- an image forming unit configured to form an image on a sheet;
- and
- one or more controllers having a processor executing instructions stored in a memory or having circuitry, configured to perform:
- processing of obtaining first print data from the external apparatus and storing, in the storage, identification information representing that image formation based on the first print data is uncompleted;
- and
- processing of obtaining second print data from the external apparatus in a status in which the identification information is not stored in the storage, and inhibiting obtaining of the second print data from the external apparatus in a status in which the identification information is stored in the storage.
A control method of an image forming apparatus capable of communicating with an external apparatus, the image forming apparatus comprising:
- a storage configured to store information;
- an image forming unit configured to form an image on a sheet;
- and one or more controllers having a processor executing the control method comprising:
- obtaining first print data from the external apparatus and storing, in the storage, identification information representing that image formation based on the first print data is uncompleted;
- obtaining second print data from the external apparatus in a status in which the identification information is not stored in the storage;
- and
- inhibiting obtaining of the second print data from the external apparatus in a status in which the identification information is stored in the storage.
A non-transitory computer-readable storage medium storing a control program configured to cause a computer to execute a control method of an image forming apparatus capable of communicating with an external apparatus, the image forming apparatus comprising:
- a storage configured to store information;
- an image forming unit configured to form an image on a sheet;
- and one or more controllers having a processor executing the control method comprising:
- obtaining first print data from the external apparatus and storing, in the storage, identification information representing that image formation based on the first print data is uncompleted;
- obtaining second print data from the external apparatus in a status in which the identification information is not stored in the storage;
- and
- inhibiting obtaining of the second print data from the external apparatus in a status in which the identification information is stored in the storage.
An image forming system comprising a server configured to manage print data, and an image forming apparatus configured to perform image formation based on print data,
- wherein the server is configured to perform:
- processing of notifying the image forming apparatus that transmissible print data exists;
- and
- processing of transmitting requested print data in accordance with a request from the image forming apparatus, and
- the image forming apparatus is configured to perform:
- processing of obtaining first print data from an external apparatus and storing identification information representing that image formation is uncompleted;
- and
- processing of receiving the notification and requesting transmission of second print data in a status in which the identification information is not stored, and receiving the notification and inhibiting request of transmission of the second print data from the server in a status in which the identification information is stored.
