Abstract
First device information, which is information independent from settings of a device or functions of a device, is obtained from a device in bulk; second device information, which is information that depends on settings of a device or functions of a device, is obtained; and the obtained first and second device information are stored in a storage unit. A device connected through communication is then specified on the basis of the obtained first device information.
Claims30
An information processing apparatus comprising:
- at least one processor causing the information processing apparatus to act as;
- a first obtainment unit that performs a first obtainment process including transmitting, using Simple Network Management Protocol (SNMP), a search packet for requesting a plurality of types of information including first information and second information, and obtaining the plurality of types of information in a response packet transmitted from a device that receives the search packet;
- and
- a second obtainment unit that performs a second obtainment process including transmitting, to the device that transmits the response packet, a request packet for requesting third information that is different from the plurality of types of information obtained by the first obtainment process, and obtaining the third information in a response packet transmitted from the device that receives the request packet,
- wherein the request packet transmitted in the second obtainment process is a packet for requesting a single type of information, and is a packet for requesting a Bonjour name, as the third information, that the second obtainment unit is able to obtain in a state that a predetermined function is turned on in the device and is not able to obtain in a state that the predetermined function is turned off in the device,
- wherein the first obtainment unit is able to obtain the plurality of types of information based on the search packet, even in the state that the predetermined function is turned off in the device, and
- wherein the second obtainment unit performs the second obtainment process after the first obtainment unit obtains the plurality of types of information, and the second obtainment unit does not perform the second obtainment process if the first obtainment unit does not obtain the plurality of types of information within a predetermined time.

An information processing method performed by an image processing apparatus, comprising:
- performing a first obtainment process including transmitting, using Simple Network Management Protocol (SNMP), a search packet for requesting a plurality of types of information including first information and second information, and obtaining the plurality of types of information in a response packet transmitted from a device that receives the search packet;
- and
- performing a second obtainment process including transmitting, to the device that transmits the response packet, a request packet for requesting third information that is different from the plurality of types of information obtained by the first obtainment process, and obtaining the third information in a response packet transmitted from the device that receives the request packet,
- wherein the request packet transmitted in the second obtainment process is a packet for requesting a single type of information, and is a packet for requesting a Bonjour name, as the third information, that the second obtainment process is able to obtain in a state that a predetermined function is turned on in the device and is not able to obtain in a state that the predetermined function is turned off in the device,
- wherein the first obtainment process is able to obtain the plurality of types of information based on the search packet, even in the state that the predetermined function is turned off in the device, and
- wherein the second obtainment process is performed after the first obtainment process obtains the plurality of types of information, and the second obtainment process is not performed if the first obtainment process does not obtain the plurality of types of information within a predetermined time.
