Abstract

Identification information for identifying each network out of a plurality of wireless networks is received. A wireless network identified by arbitrary identification information is wirelessly connected. Whether a printer in the wirelessly connected wireless network has a function of connecting a digital camera and performing output processing is inquired of the printer. Connection to the printer is controlled in accordance with a response to the inquiry. The digital camera performs output processing together with the connected printer. An information output apparatus having a function of connecting an information storage terminal apparatus by simple operation and performing output processing can be wirelessly connected.

Claims

1. An information processing apparatus, comprising:

a scanning unit configured to scan a beacon signal sent from each of a plurality of access points operating in accordance with a wireless LAN defined by IEEE 802.11 series standard;

a first determination unit configured to determine whether a printer having a predetermined function exists in a wireless network identified by identification information included in the beacon signal transmitted by one of the plurality of access points;

a second determination unit configured to determine, if the first determination unit determined that no printer having the predetermined function exists, whether a printer having the predetermined function exists in a wireless network identified by identification information included in the beacon signal transmitted by another one of the plurality of access points;

a transmission unit configured to transmit a print request to the printer having the predetermined function based on the determination result by the first determination unit or the second determination unit,

wherein the plurality of access points include a printer which is operating as an access point, and the transmission unit directly transmits, if the printer having the predetermined function is the printer which is operating as an access point, the print request to the printer which is operating as an access point without going through an external access point.

2. The information processing apparatus according to claim 1, further comprising:

an inquiring unit configured to inquire, of an access point in the plurality of wireless networks, whether the access point has a function of performing a print processing; and

a control unit configured to control connection to the access point in accordance with a response to the inquiry.

3. The information processing apparatus according to claim 2, wherein the control unit controls, if the response to the inquiry is a positive response, to connect to the access point which has positively responded.

4. The information processing apparatus according to claim 2, wherein the control unit controls, if a plurality of access points which have positively responded exists, to connect to one of the plurality of access points which has first positively responded.

5. The information processing apparatus according to claim 4, wherein the control unit controls, if a plurality of access points which have positively responded exists and the print processing together with the one of the plurality of access points which has first positively responded abnormally ends, to connect to another access point of the plurality of access points which has positively responded.

6. The information processing apparatus according to claim 2, wherein the control unit controls, if the response to the inquiry is a negative response or no response exists, to connect to another access point in a wireless network other than the wirelessly connected wireless network.

7. The information processing apparatus according to claim 2, wherein the inquiry is performed by a broadcast message.

8. The information processing apparatus according to claim 1, wherein the information processing apparatus wirelessly communicates in a communication mode according to an infrastructure mode defined by IEEE 802.11.

9. The information processing apparatus according to claim 1, wherein the information processing apparatus wirelessly communicates in a communication mode according to an ad-hoc mode defined by IEEE 802.11.

10. A method for processing information, comprising the steps of:

scanning a beacon signal sent from each of a plurality of access points operating in accordance with a wireless LAN defined by IEEE 802.11 series standard;

a first determination step of determining whether a printer having a predetermined function exists in a wireless network identified by identification information included in the beacon signal transmitted by one of the plurality of access points;

a second determination step of determining, if the first determination step determined that no printer having the predetermined function exists, whether a printer having the predetermined function exists in a wireless network identified by identification information included in the beacon signal transmitted by another one of the plurality of access points;

transmitting a print request to the printer having the predetermined function based on the determination result of the first determination step or the second determination step,

wherein the plurality of access points include a printer which is operating as an access point, and the transmission step directly transmits, if the printer having the redetermined function is the printer which is operating as an access point, the print request to the printer which is operating as an access point without going through an external access point.

11. A non-transitory computer-readable storage medium storing a computer program, the computer program causing a computer to execute a method comprising the steps of:

scanning a beacon signal sent from each of a plurality of access points operating in accordance with a wireless LAN defined by IEEE 802.11 series standard;

a first step of determining whether a printer having a predetermined function exists in a wireless network identified by identification information included in the beacon signal transmitted by one of the plurality of access points;

a second determination step of determining, if the first determination step determined that no printer having the predetermined function exists, whether a printer having the predetermined function exists in a wireless network identified by identification information included in the beacon signal transmitted by another one of the plurality of access points;

transmitting a print request to the printer having the predetermined function based on the determination result by the first determination step or the second determination step,

wherein the plurality of access points include a printer which is operating as an access point, and the transmission step directly transmits, if the printer having the redetermined function is the printer which is operating as an access point, the print request to the printer which is operating as an access point without going through an external access point.
