Abstract
An information processing apparatus connected to an image forming apparatus over a wireless network broadcasts a packet to the wireless network to identify the current address of the image forming apparatus, unicasts a packet to a default address of the image forming apparatus to identify the current address of the image forming apparatus, or identifies the current address of the image forming apparatus based on an address of the information processing apparatus in the wireless network and information regarding a connection state of the network of the information processing apparatus so that the current address of the image forming apparatus can be identified to transmit print data to the identified address.
Claims13
An information processing apparatus, comprising:
- a connection unit configured to connect to an image forming apparatus over a wireless network;
- a first identifying unit configured to broadcast a packet to the wireless network and identify a current address of the image forming apparatus from a response packet to the packet;
- a second identifying unit configured to unicast a packet to a default address of the image forming apparatus on the wireless network and, if a response packet to the packet is received, to identify that the current address of the image forming apparatus is the default address;
- a third identifying unit configured to, if the first identifying unit and the second identifying unit do not identify the current address of the image forming apparatus, obtain an address of the information processing apparatus in the wireless network and information regarding a connection state of the network of the information processing apparatus and identify the current address of the image forming apparatus based on the address of the information processing apparatus and the information regarding the connection state of the network of the information processing apparatus;
- and
- a transmitting unit configured to transmit print data to the identified current address of the image forming apparatus.
A control method for an information processing apparatus, the method comprising:
- connecting to an image forming apparatus over a wireless network;
- broadcasting a packet to the wireless network;
- identifying a current address of the image forming apparatus from a response packet to the packet;
- unicasting a packet to a default address of the image forming apparatus on the wireless network, wherein, if a response packet to the packet is received, identifying that the current address of the image forming apparatus is the default address;
- obtaining, if the current address of the image forming apparatus is not identified and the default address is not identified as the current address of the image forming apparatus, an address of the information processing apparatus in the wireless network and information regarding a connection state of the network of the information processing apparatus and identifying the current address of the image forming apparatus based on the address of the information processing apparatus and the information regarding the connection state of the network of the information processing apparatus;
- and
- transmitting print data to the identified current address of the image forming apparatus.
A non-transitory recording medium storing instructions to be executed in a computer, the instructions causing the computer to:
- connect to an image forming apparatus over a wireless network;
- broadcast a packet to the wireless network;
- identify a current address of the image forming apparatus from a response packet to the packet;
- unicast a packet to a default address of the image forming apparatus on the wireless network wherein, if a response packet to the packet is received, identify that the current address of the image forming apparatus is the default address;
- obtain, if the current address is not identified and the default address is not identified as the current address of the image forming apparatus, an address of the information processing apparatus in the wireless network and information regarding a connection state of the network of the information processing apparatus and identify the current address of the image forming apparatus based on the address of the information processing apparatus and the information regarding the connection state of the network of the information processing apparatus;
- and
- transmit print data to the identified current address of the image forming apparatus.
