  As illustrated in FIG. 2, the printing apparatus 2 as a data processing apparatus includes a printing unit 21, a wireless communication unit 22, and a control unit 23. The printing unit 21 includes an actuator, a sensor, a drive circuit, and a mechanical part for executing printing on a printing medium such as photographic paper, plain paper, and an OHP sheet in a known printing method such as an electrophotographic method or an inkjet method. . The wireless communication unit 22 functioning as the first communication unit and the second communication unit includes an electronic circuit for performing wireless communication according to IEEE 802.11. The wireless communication unit 22 performs wireless LAN communication using the access point 4 as a relay device, and wireless communication conforming to Wi-Fi Direct (hereinafter abbreviated as WFD) which is a P2P wireless communication standard that does not relay the access point 4. It corresponds to. The control unit 23 includes a CPU, a main memory, a nonvolatile memory, an input / output circuit, and the like (not shown). The control unit 23 controls the printing unit 21 and the wireless communication unit 22 by loading a control program stored in the nonvolatile memory into the main memory and executing it by the CPU. In addition to the OS (Operating System), this control program includes a data processing program that causes the control unit 23 to function as the WFD communication unit 231, the print management unit 232, and the print control unit 233. Here, it is assumed that the printing control unit 233 controls the printing unit 21 based on data in the PWG-Raster format. That is, it is assumed that the printing apparatus 2 can print only the data in the PWG-Raster format alone. The print control unit 233 corresponds to an “output unit”. The PWG-Raster format corresponds to a “data format that can be processed by the output unit”. In this embodiment, the “data format that can be processed by the output unit” is also referred to as a “second data format”.

  As shown in FIG. 2, the server 3 includes a communication unit 31 and a control unit 32. The communication unit 31 includes an electronic circuit for performing communication according to the Internet protocol. The control unit 32 includes a CPU, main memory, ROM, input / output circuit, external storage device, and the like (not shown). The control unit 32 controls the communication unit 31 by loading various programs into the main memory and executing them by the CPU. The program executed by the control unit 12 includes a data conversion program that causes the control unit 32 to function as the data conversion unit 321 in addition to the OS. Here, it is assumed that the data conversion unit 321 can convert data in PDF format into data in PWG-Raster format. Therefore, the PDF format corresponds to “a data format that can be processed by the output unit by the server conversion process” and “a data format that the output unit does not support”. In this embodiment, “a data format that can be processed by the output unit by the server conversion process” and “a data format that the output unit does not support” are also referred to as a “first data format”.

  The smartphone 1 includes a control unit including a CPU, a main memory, a nonvolatile memory, an input / output circuit, and the like (not shown), a touch panel display, and a wireless communication unit. The program executed by the control unit includes an OS that supports WFDPS and a document management program for storing, displaying, transmitting, and the like.

2. Data Processing Method Next, a data processing method in which the printing apparatus 2 prints image data selected by the user of the smartphone 1 will be described with reference to FIG.
The printing apparatus 2 communicates with the server 3 at a predetermined timing, and acquires a data format that can be converted by the server 3 (S0). Specifically, for example, the print management unit 232 is a data format that the server 3 can convert to the server 3 at a predetermined timing such as when the printing apparatus 2 is turned on or at a predetermined time interval or time. The print management unit 232 specifies and stores a data format in which the server 3 can convert the data into the PWG-Raster format (second data format) for which the print management unit 232 accepts input. When the printing apparatus 2 acquires a list of data formats that can be converted by the server 3 from the server 3 as needed, the opportunity for the user of the smartphone 1 to use the printing function of the printing apparatus 2 is expanded according to the function expansion of the server 3. The list of data formats that can be converted by the server 3 is information as shown in Table 1 below, for example. The list in Table 1 shows an example in which the server 3 can convert PDF format data into PWG-Raster format data and PCLm format data, and can convert PCLm format data into PWG-Raster format data.

  The printer 2 that has acquired a data format that can be converted by the server 3 updates the data format information indicating the printable data format (S1). Specifically, the print management unit 232 can print a second data format that can be input to the print control unit 233 and printed, and a first data format that the server can convert to the second data format. Data format information is updated as a simple data format (a data format that can be output by the data processing apparatus). Here, the first data format that can be converted into the second data format by the server 3 is updated to the first data format acquired last from the server 3 to notify the smartphone 1 as a data format that can be printed by the printing apparatus 2. The data format to be matched can be matched with the connection state between the server 3 and the printing apparatus 2. That is, in a state where the printing apparatus 2 is not connected to the server 3, it is possible to prevent the smartphone 1 from being notified of a data format that the printing apparatus 2 cannot print independently as a printable data format. For example, as shown in Table 2 below, the data format information includes characters indicating the data format and the data format is a first data format that can be printed by the printing apparatus 2 alone, or data conversion by the server 3 is necessary. This information includes characters or flags indicating whether the second data format is used.

The processing after S2 shown in FIG. 3 is started when the user of the smartphone 1 selects data using a document management program and instructs printing.
When the user of the smartphone 1 selects data and instructs printing, the control unit of the smartphone 1 broadcasts a message inquiring about a printable data format according to the WFD standard (S2). In the following description, it is assumed that the user has selected a PDF file and instructed printing.

  When the smartphone 1 is in a place where it can communicate with the printing apparatus 2 by WFD, the printing apparatus 2 receives a message broadcast from the smartphone 1 and returns a printable data format to the smartphone 1 according to the WFD standard. (S3). At this time, the print management unit 232 returns a printable data format based on the data format information updated to the latest state. Therefore, when the printing apparatus 2 and the server 3 are connected, the first data format (PDF) and the second data format (PWG-Raster) are returned as printable data formats. When the printing apparatus 2 and the server 3 are not connected, only the second data format (PWG-Raster) is returned as a printable data format.

  When the smartphone 1 receives a reply to the broadcast message, the smartphone 1 selects a data processing apparatus that requests printing (S4). Specifically, the control unit of the smartphone 1 collates the returned data format with the data format to be printed, and sends the data processing apparatus that has returned the data format to be printed as a printable data format to the print request destination. Choose as. In this embodiment, a PDF file is selected by the user, and the printing apparatus 2 returns the PDF format as a printable data format. Therefore, the printing apparatus 2 is selected as a data processing apparatus that requests printing.

  Next, the smartphone 1 establishes a connection between the printing apparatus 2 selected as the data processing apparatus that requests printing and the WFD according to the standard (S5). Specifically, an SSID (Service Set Identifier) and an encryption key are shared between the printing apparatus 2 and the smartphone 1 by wireless communication, and the smartphone 1 and the printing apparatus 2 are connected without the access point 4.

  When the WFD connection is established, the smartphone 1 transmits the data selected as the print target to the printing apparatus 2 (S6).

  When the print target data is received, the printing apparatus 2 determines whether the data format of the print target data is the first data format or the second data format (S7). Specifically, the print management unit 232 determines whether the received data is in the first data format (PDF format) that needs to be converted by the server 3 or the second data format (can be processed by the print control unit 233 without conversion). PWG-Raster format) is determined using the data format information.

  When the print target data is in the second data format, the printing apparatus 2 executes printing alone (S3). Specifically, the print control unit 233 generates print data by performing processing such as color conversion, resolution conversion, halftoning, and interlacing on the print target data in the PWG-Raster format, and generates the generated print data in the print unit 21 to execute printing.

  If the print target data is in the first data format, the printing apparatus 2 requests the server 3 to convert the print target data (S8). Specifically, the print management unit 232 transmits to the server 3 a request message using parameters such as the data format, data size, etc. before and after conversion of the print target data.

  The data conversion unit 321 of the server 3 that has received the request message requests the printing apparatus 2 for data to be printed (S9).

  When the print target data is requested, the printing apparatus 2 transfers the print target data in the first data format to the server 3 (S10). Specifically, the print management unit 232 transmits PDF format print target data to the server 3.

  When the print target data is received, the data conversion unit 321 of the server 3 converts the print target data from the first data format (PDF format) to the second data format (PWG-Raster format) (S11).

  Subsequently, the data conversion unit 321 of the server 3 transmits the print target data converted into the second data format to the printing apparatus 2 (S12).

  As a result, the printing apparatus 2 receives the print target data in the second data format. That is, the printing apparatus 2 has converted the print target data in the first data format into the second data format by communicating with the server 3.

  Subsequently, the printing apparatus 2 prints the print target data in the second data format (S13). Specifically, the print control unit 233 generates print data by performing processing such as color conversion, resolution conversion, halftoning, and interlacing on the print target data in the PWG-Raster format, and generates the generated print data in the print unit 21 to execute printing.

  According to the data processing system described above, in addition to the PWG-Raster format that the printing device 2 can print independently, the PDF format that the printing device 2 cannot print alone is notified to the smartphone 1 as a data format that the printing device 2 can print. Therefore, in WFDPS, the opportunity for the printing apparatus 2 to become a candidate for an apparatus that can use the printing function is expanded. The printing apparatus 2 communicates with the server 3 and converts the data in the PDF format into the PWG-Raster format by causing the server 3 to convert the data. Thus, the PDF format data that cannot be printed alone is received from the smartphone 1. Can be printed. Therefore, the opportunity for using the printing apparatus 2 from the smartphone 1 can be expanded.

  Further, in order to update the data format information according to the connection state between the printing apparatus 2 and the server 3, an appropriate data format according to the connection state between the printing apparatus 2 and the server 3 is stored in the smartphone 1 as a printable data format. You can be notified.

4). Other Embodiments The technical scope of the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be made without departing from the scope of the present invention.
Hereinafter, embodiments in which the above-described examples are modified will be exemplified.

  The present invention can be applied not only to a printing apparatus but also to a data output apparatus such as a projector for projecting an image or a display, to a data input apparatus such as a scanner or a digital camera, or to a data communication apparatus such as a facsimile. it can.

FIG. 4 shows a data processing system configured by applying the data processing apparatus of the present invention to a scanner. As shown in FIG. 4, the scanner 5 as a data processing apparatus includes a reading unit 51, a wireless communication unit 52, and a control unit 53. The reading unit 51 includes a line image sensor, a driving circuit, and a sub-scanning mechanism for reading an image from a document in a known image reading method. The wireless communication unit 52 functioning as the first communication unit and the second communication unit includes an electronic circuit for performing wireless LAN communication according to IEEE 802.11. The control unit 53 includes a CPU, a main memory, a nonvolatile memory, an input / output circuit, and the like (not shown). The control unit 53 controls the reading unit 51 and the wireless communication unit 52 by loading a control program stored in the nonvolatile memory into the main memory and executing it by the CPU. In addition to the OS, this control program includes a data processing program that causes the control unit 53 to function as the WFD communication unit 531, the read management unit 532, and the read control unit 533. Here, it is assumed that the reading control unit 533 converts the output of the reading unit 51 into GIF format image data. That is, the scanner 5 can output only GIF data alone. The reading control unit 533 corresponds to an “output unit”. The GIF format “corresponds to a data format that can be processed by the output unit.”
The data conversion unit 321 of the server 3 shown in FIG. 4 converts GIF format data into PNG format data. Accordingly, the PNG format corresponds to “a data format that can be processed by the output unit by server conversion processing” and “a data format that the output unit does not support”.

Next, a data processing method for transmitting image data read by the scanner 5 to the smartphone 1 will be described with reference to FIG.
The scanner 5 communicates with the server 3 at a predetermined timing and acquires a data format that can be converted by the server 3 (S0). The scanner 5 having acquired the data format that can be converted by the server 3 updates the data format information indicating the data format that can be output (S21). When the user of the smartphone 1 inputs a reading request, the control unit of the smartphone 1 broadcasts a message inquiring about a data format that can be output in accordance with the WFD standard (S22). Here, it is assumed that the smartphone 1 cannot display GIF format image data and can display PNG format image data. When the smartphone 1 is in a place where wireless communication with the scanner 5 is possible, the scanner 5 receives a message broadcast from the smartphone 1 and returns a data format that can be output to the smartphone 1 according to the WFD standard ( S23). When the smartphone 1 receives a reply to the broadcast message, the smartphone 1 selects a data processing device to request reading (S24). The smartphone 1 cannot display GIF format image data but can display PNG format image data, and the scanner 5 returns the PNG format as a printable data format, so that the scanner is a data processing device that requests reading. 5 is selected. Next, the scanner 5 establishes a connection between the scanner 5 selected as the data processing device to request reading and the WFD according to the standard (S25). When the WFD connection is established, the user sets an original on the scanner 5 and instructs the printing apparatus 2 to read from the smartphone 1 (S26). At this time, the smartphone 1 specifies the format of the output data in the PNG format. The scanner 5 instructed to read reads the set original (S27). As a result, the reading control unit 533 of the scanner 5 acquires GIF format image data. Subsequently, the scanner 5 determines whether the format of the output data instructed to the smartphone 1 is the first data format other than the GIF format or the GIF format (second data format) generated by the reading control unit 533. (S28). When the instructed output data is in the second data format (GIF format), the scanner 5 transmits the output data in the second data format (GIF format) generated by the reading control unit 533 to the smartphone 1 (S34). If the instructed output data is in the first data format (PNG format), the scanner 5 requests the server 3 to convert the output data (S29). When output data in the second data format is requested from the server 3 (S30), the scanner 5 transmits output data in the second data format (GIF format) to the server 3 (S31). Upon receiving the output data in the second data format, the server 3 converts the output data into the first data format (PNG format) (S32), and transmits the output data in the first data format to the scanner 5 (S33). The scanner 5 transmits the output data in the first data format (PNG format) received from the server 3 to the smartphone 1 (S34).

  As described above, when the present invention is applied to the scanner, data in the first data format that cannot be output alone even when the scanner 5 reads an image can be output to the smartphone 1. Therefore, the opportunity for the smartphone 1 to use the scanner 5 can be expanded.

In addition, the data processing device may notify the wireless communication terminal that data of a plurality of first data formats can be output, or wireless communication that data of a plurality of first data formats can be output. You may notify a terminal.
The determination as to whether the data processing device is connected to the server may be made when an inquiry about a data format that can be output from the wireless communication terminal is received.
In addition, the wireless communication method between the data processing device and the wireless communication terminal may be a P2P method other than WFD. Further, instead of IEEE802.11, a wireless communication system such as BlueTooth, infrared communication (IrDA, etc.) or near field wireless communication (NFC, etc.) may be used. Further, the data processing device and the server may be connected via a LAN or may be connected via a dedicated communication line.
Further, the server may be composed of a single computer, or may be composed of a plurality of computers connected via a LAN or the Internet.
