Image forming apparatus and image forming method
View Patent ↗An image forming apparatus may include an image forming unit configured to form an image on a printing medium and a control unit configured to perform at least one of a user authentication operation, an image forming preparation operation, and an image forming operation according to distance information between a portable electronic device and the image forming apparatus.
1. An image forming apparatus, comprising:
an image forming unit;
a communication interface configured to receive, from a mobile device, information about a distance between the image forming apparatus and the mobile device; and
a controller configured to control the image forming unit to print an image on a medium when the information indicates the mobile device is less than a first predefined distance from the image forming apparatus, and to perform an operation to notify the mobile device of an unreceived medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
2. The image forming apparatus of claim 1 , wherein the controller is configured to control the communication interface to transmit a message to the mobile device requesting receipt of the medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
3. The image forming apparatus of claim 1 , wherein the controller is configured to control the communication interface to transmit a message to the mobile device requesting selection of a recipient of the medium.
4. The image forming apparatus of claim 3 , wherein the controller is configured to control the communication interface to transmit a message to a mobile device of the recipient requesting receipt of the medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than a second predefined distance from the image forming apparatus, and
the second predefined distance is greater than the first predefined distance.
5. The image forming apparatus of claim 4 , wherein the controller is configured to perform an authentication operation of the recipient in response to receiving authentication information of the recipient.
6. The image forming apparatus of claim 1 , wherein the controller is configured to control the communication interface to transmit a message to the mobile device and another mobile device requesting receipt of the medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
7. The image forming apparatus of claim 6 , wherein the controller is configured to perform an authentication operation of the another mobile device in response to receiving authentication information of the another mobile device.
8. The image forming apparatus of claim 1 , wherein the controller is configured to control the communication interface to transmit an advertising signal at a predetermined period and to receive the information about the distance in response to the transmission of the advertising signal.
9. The image forming apparatus of claim 8 , wherein the advertising signal includes information about an output intensity of the communication interface for outputting the advertising signal.
10. The image forming apparatus of claim 1 , wherein the controller is configured to convert the image forming apparatus to a standby mode when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
11. A controlling method of an image forming apparatus, comprising:
receiving, from a mobile device, information about a distance between the image forming apparatus and the mobile device;
printing an image, by an image forming unit, on a medium when the information indicates the mobile device is less than a first predefined distance from the image forming apparatus; and
performing a warning operation to notify the mobile device of an unreceived medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
12. The controlling method of claim 11 , wherein the performing of the warning operation comprises transmitting a message to the mobile device requesting receipt of the medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
13. The controlling method of claim 11 , wherein the performing of the warning operation further comprises transmitting a message to the mobile device requesting selection of a recipient of the medium.
14. The controlling method of claim 13 , wherein the performing of the warning operation further comprises transmitting a message to a mobile device of the recipient requesting receipt of the medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than a second predefined distance from the image forming apparatus, and the second predefined distance is greater than the first predefined distance.
15. The controlling method of claim 14 , wherein the performing of the warning operation further comprises performing an authentication operation of the recipient in response to receiving authentication information of the recipient.
16. The controlling method of claim 11 , wherein the performing of the warning operation comprises transmitting a message to the mobile device and another mobile device requesting receipt of the medium on which the image forming unit has printed the image when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
17. The controlling method of claim 16 , wherein the performing of the warning operation further comprises performing an authentication operation of the another mobile device in response to receiving authentication information of the another mobile device.
18. The controlling method of claim 11 , further comprising transmitting an advertising signal at a predetermined period, and receiving the information about the distance in response to transmitting the advertising signal.
19. The controlling method of claim 18 , wherein the advertising signal includes information about an output intensity for outputting the advertising signal.
20. The controlling method of claim 11 , further comprising converting the image forming apparatus to a standby mode when the information indicates the mobile device is greater than the first predefined distance from the image forming apparatus.
