Description
The present invention relates to a wireless access point.
Some conventional notebook personal computers (PCs) and PDAs perform wireless LAN communication using a wireless LAN card inserted into the main body. As a wireless LAN system, IEEE802.11b is frequently used, but besides this, IEEE802.11g and IEEE802.11a are also used, and there are other standards.
A PC or PDA that performs communication by these wireless LANs is connected to the Internet or the like via a wireless LAN access point. This wireless LAN access point is wirelessly connected to a PC or PDA that performs communication by wireless LAN, and is connected to an intranet or the Internet by wire.
When this wireless LAN access point is used in a conference room, for example, it is desirable to have not only a display function but also an output function to a printer. In this case, the wireless LAN access point has a wireless or wired printer. Are connected (see Patent Document 1).
However, a PC or PDA that is wirelessly connected to a wireless LAN access point must be installed with a driver for a printer that is wirelessly or wiredly connected to the wireless LAN access point, which hinders the use of the printer. .
It is an object of the present invention to provide a wireless access point that can easily use a connected printer from an information processing apparatus such as a PC that performs wireless communication.
To achieve the above object, the wireless access point according to claim 1 is connected to an external service, wirelessly connected to an information processing apparatus, and provided with a USB terminal to which a device is to be connected. An adding means for adding an IP address to a device connected to the USB terminal, and the external service together with the IP address to change desired data to be processed by the device to correspond to the device connected to the USB terminal And a receiving means for receiving desired data modified to correspond to the device by the external service based on the IP address.
According to the present invention, an IP address is added to a device connected to a USB terminal, and desired data to be processed by the device is sent to an external service together with the IP address so as to change to correspond to the device connected to the USB terminal. Since the desired data changed to correspond to the device by the external service is received based on the IP address, the connected device can be easily used from an information processing apparatus such as a wirelessly connected PC. it can.
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram schematically showing a configuration of a wireless access point according to an embodiment of the present invention.
The wireless LAN access point 101 in FIG. 1 is connected to a wireless client PC 171 by a wireless LAN and connected to Web services 161 and 162 (external services) via the Internet 151. The wireless client PC 171 operates on an OS of Windows (registered trademark) XP (registered trademark).
The wireless LAN access point 101 includes a wireless LAN interface 121 that is wirelessly connected to the wireless client PC 171, a USB interface 131 that is connected to a printer (not shown), and a USP / IP conversion unit 132 that is connected in series to the USB interface 131. And the DHCP 133, and the middleware 111 connected to the USP / IP conversion unit 132 and the DHCP 133, respectively.
The middleware 111 includes a device proxy unit 113 having a Web service stack 114 connected to the Internet 151 by wire, and a UPnP (Universal Plug and Play) stack 112 connected to the device proxy unit 113.
The wireless access point 101 has a UPnP function by the UPnP stack 112. This UPnP function is set so that the wireless LAN access point 101 can be seen as a UPnP printer.
When the explorer of the OS is started in the wireless client PC 171, a UPnP printer mark is displayed (UPnP printer pop-up). When this mark is clicked, the information is transmitted to the wireless LAN access point 101 via the wireless LAN interface 121. To the device proxy unit 113. The device proxy unit 113 displays a print instruction screen shown in FIG. 2 described later on the display screen of the wireless client PC 171. In addition, data including use, conditions, and capabilities of the printer connected to the USB interface 131 is sent to the device proxy unit 113. The DHCP 133 assigns an appropriate IP (Internet Protocol) address to the connected printer (adding means), and the USB / IP conversion unit 132 associates the USB input with the IP address.
FIG. 2 is a diagram used to explain a screen displayed on the display screen of the wireless client PC 171 in FIG.
The screen of FIG. 2 displays a list 202 of files to be printed (ABC, HIG) or still image data (photos of athletic meet), and a print button 201 of “print when pressed here”. The list 202 is accompanied by the description “Please select data or file”.
With the screen shown in FIG. 2, a file to be printed in the wireless client PC 171 can be designated, and printing can be started.
When a desired file or the like is selected and clicked from the list 202 and the print button 201 is clicked, a print is output from the printer connected to the USB interface 131 of the wireless LAN access point 101.
When the print button 201 is clicked, the device proxy unit 113 knows the use, conditions, and capabilities of the connected printer, so that data such as a file designated by the wireless client PC 171 is connected to the printer. An IP address is sent to the Web services 161 and 162 to be converted into a printable format (sending means). The Web services 161 and 162 recognize the wireless LAN access point 101 itself as an IP printer having an IP address assigned to the connected printer, and the converted data is converted to IP by the device proxy unit 113. The wireless LAN access point 101 receives the data (reception unit), receives the converted data, sends it to the printer, and outputs a print.
According to the present embodiment, when data such as a file to be printed is designated in the wireless client PC 171 on the screen of FIG. 2 and printing is started, the specifications, conditions and capabilities of the printer connected from the USB are designated. And the corresponding data conversion is performed by the Web service, the result is returned to the equivalent IP printer, and the received conversion data is sent to the connected printer. You can find out what the connected printer is like, and eliminate the need to install a driver for that printer.
In this embodiment, the first operation is performed by using the UPnP function. However, a URL indicating an appropriate access point is input, and a screen for instructing printing is displayed by performing redirection within the access point. May be. In that case, the browser screen is configured.
In this embodiment, the service for converting printer data is a Web service. However, the service is not necessarily limited to a Web service, and any service that performs conversion is sufficient.
