  However, in circulation type communication by a conventional facsimile apparatus including the technique described in Patent Document 1 described above, image conversion is performed by a transmission source facsimile apparatus in accordance with the capability of the transmission destination facsimile apparatus. Since the processing is performed, if a facsimile apparatus with low capability exists in the circulation destination, the image data is deteriorated when the image data is transferred to the facsimile apparatus. there were. In other words, in the conventional circulation format communication, the quality of the output image is determined in accordance with the facsimile apparatus having the lowest image data reproduction capability among the facsimile apparatuses existing in the circulation route, which is higher than the assumed quality. There was a problem that only a degraded output image could be obtained.

  SUMMARY An advantage of some aspects of the invention is that it provides an image forming apparatus capable of obtaining a high-quality output image without deterioration when performing circulation-type communication.

Further, the transfer control means may transfer the image information stored in the storage means to a destination extracted from the destination information added to the image information. In the latter case, the transfer control unit generates new destination information indicating another device to which the image information stored in the storage unit is to be transmitted, and stores the generated destination information in the storage unit. It is added to the image information and transferred to the extracted destination. Thereby, in the image forming apparatus according to the present invention, since it is not necessary to store the destination information in the storage unit, the memory capacity can be reduced compared to the former in which the destination information needs to be stored in the storage unit. Can do. Note that the transfer control unit can stop the transfer of the image information stored in the storage unit when the information of another device is not registered in the destination information.

  In addition, the transfer control unit compares the transmitted image information stored in the storage unit with the received image information, and based on the comparison result, whether or not the data transfer is normally completed.

A high-quality output image can be obtained by the forming apparatus.

  Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings.

  This embodiment is an image forming system that uses a plurality of printers as image forming apparatuses that form an image on a predetermined recording medium and performs circulation-type communication.

  First, the image forming system shown as the first embodiment will be described. Here, for convenience of explanation, it is assumed that circulation-type communication is performed by two printers connected to the network.

  In the image forming system, for example, as shown in FIG. 1, two printers 100 and 200 are connected to a predetermined network 310 such as a LAN (Local Area Network), a WAN (Wide Area Network), and / or the Internet. Composed.

  The printers 100 and 200 respectively store storage units 101 and 201 that store image information input from the outside, and control when transferring the image information stored in the storage units 101 and 201 to other printers. Transfer control units 102 and 202 for performing control, network interface controller (NIC) units 103 and 203 for performing control for connection to the network 310, and image information in a format capable of forming an image. Image conversion units 104 and 204 for converting to image data, and image forming units 105 and 205 for forming an image on a predetermined recording medium based on the image data converted by the image conversion units 104 and 204 are provided.

  In the image forming system, for example, as illustrated in FIG. 2, an information processing apparatus 300 including a personal computer or the like is connected to a network 310. The information processing apparatus 300 generates application data to be formed by executing an application program 301 such as image display software or document creation software by a CPU (Central Processing Unit) (not shown). In addition, the information processing apparatus 300 executes a printer driver 302 by a CPU (not shown) or the like, thereby generating generated application data with a predetermined page description language (Page Description Language; (Referred to as PDL). The information processing apparatus 300 transmits the PDL data generated by the printer driver 302 to the printers 100 and 200 via the NIC unit 304 under the control of the transfer control unit 303.

  In such an image forming system including the printers 100 and 200 and the information processing apparatus 300, for example, as illustrated in FIG. 3, image information including PDL data generated by the information processing apparatus 300 is transmitted via the network 310. Are transmitted to the printer 100. In the image forming system, image information is transmitted from the printer 100 to the printer 200 via the network 310 to perform circulation-type communication. Specifically, in the image forming system, circulation-type communication is performed according to a series of procedures as shown in FIGS.

  First, as illustrated in FIG. 4, the information processing apparatus 300 converts application data generated by the application program 301 into PDL data by the printer driver 302 in step S <b> 11. In step S <b> 12, the information processing apparatus 300 transmits the generated PDL data to the printer 100 connected to the network 310 under the control of the transfer control unit 303. The information processing apparatus 300 transmits PDL data using a protocol such as so-called IPP (Internet Printing Protocol) or SMTP (Simple Mail Transfer Protocol).

  Accordingly, as shown in FIG. 5, when the printer 100 receives the PDL data transmitted from the information processing apparatus 300 via the NIC unit 103 in step S <b> 21, the printer 100 stores the PDL data in the storage unit 101. At the same time, the PDL data is converted into image data in a format that allows image formation by the image conversion unit 104, and image formation by the image forming unit 105 is performed based on the converted image data.

  When the image forming process is completed in step S22, the printer 100 performs the storage unit based on the destination information stored in advance in the storage unit 101 under the control of the transfer control unit 102 in step S23. The PDL data stored in 101 is transferred to the printer 200 using a designated communication protocol. Here, the destination information indicates another printer to which the PDL data is to be transferred. The printer 100 can register a plurality of printers as destination information and can select a destination to be transferred. Specifically, as shown in FIG. 7, the printer 100 designates a destination such as an IP (Internet Protocol) address of another printer to which PDL data is to be transferred, and a communication protocol to be used for data transfer. Information is stored in the storage unit 101 in advance. Here, it is assumed that the destination of the printer 200 is selected and designated as shown in FIG.

  In the image forming system, when the PDL data is transmitted from the printer 100 as described above, the printer 200 converts the PDL data transmitted from the printer 100 into the NIC unit 203 in step S31 as shown in FIG. And storing the PDL data in the storage unit 201, converting the PDL data into image data in a format that can be formed by the image conversion unit 204, and then, based on the converted image data, Image formation by the image forming unit 205 is performed.

  When the image forming process is completed in step S32, the printer 200 stores the storage unit based on the destination information stored in advance in the storage unit 201 under the control of the transfer control unit 202 in step S33. An attempt is made to transfer the PDL data stored in 201 to another printer using a designated communication protocol. Here, as shown in FIG. 8, when the printer 200 stores destination information indicating that there is no other printer to which the PDL data is to be transferred, in the storage unit 201, the PDL data of the PDL data is displayed at this time. The transfer is stopped and a series of processing is terminated.

  As described above, in the image forming system, the PDL data is sequentially transferred based on the destination information stored in the storage units 101 and 201 of the printers 100 and 200, thereby enabling circulation-type communication.

  As described above, in the image forming system shown as the first embodiment of the present invention, the printers 100 and 200 are destination information indicating other printers to which PDL data should be transferred in advance to the storage units 101 and 201, respectively. , And the received PDL data is stored in the storage units 101 and 201, and the stored PDL data is directly transferred from the destination information by selecting another printer to be transferred. Data transfer can be performed without performing image conversion processing in accordance with the capability of the printer that is the data transmission destination. Therefore, in this image forming system, the quality of the output image is not determined according to the printer having the lowest image data reproduction ability among the printers existing in the circulation path, and all the printers existing in the circulation path. As a result, a high-quality output image can be obtained.

  Next, an image forming system shown as the second embodiment will be described.

  The image forming system shown as the second embodiment does not store destination information in the storage unit of each printer in advance, but adds destination information to data transmitted from the information processing apparatus. Therefore, in the description of the second embodiment, the same components as those in the description of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Here, for convenience of explanation, it is assumed that circulation-type communication is performed by three printers connected to the network.

  For example, as shown in FIG. 9, the image forming system is configured by connecting three printers 100, 200, and 400 and an information processing apparatus 300 (not shown) to a predetermined network 310.

Specifically, in the image forming system, circulation-type communication is performed according to a series of procedures as shown in FIGS.

  First, as shown in FIG. 11, the information processing apparatus 300 converts application data generated by the application program 301 into PDL data by the printer driver 302 in step S41. In step S42, the information processing apparatus 300 generates destination information indicating a printer to which PDL data is to be transmitted from now on under the control of the transfer control unit 303. Specifically, as illustrated in FIG. 15, the information processing apparatus 300 transfers the PDL data by the destination of the information processing apparatus 300 that is the transmission source of the PDL data and the printer 100 that is the transmission destination of the PDL data. The destination information describing the list of destinations of the printers 200 and 400 and the transfer priority of the destinations of the printers 200 and 400 is generated. In step S43, the information processing apparatus 300 adds the generated destination information to the PDL data under the control of the transfer control unit 303, and transmits this data to the printer 100 connected to the network 310. To do.

  In response to this, when the printer 100 receives the PDL data to which the destination information transmitted from the information processing apparatus 300 is added via the NIC unit 103 in step S51, as shown in FIG. The PDL data is stored in the storage unit 101, converted into image data in a format that can be formed by the image conversion unit 104, and an image is formed by the image forming unit 105 based on the converted image data.

  Subsequently, when the image forming process is completed in step S52, the printer 100 has the highest priority based on the destination information received from the information processing apparatus 300 under the control of the transfer control unit 102 in step S53. The destination of the printer 200 is extracted as a high destination, and new destination information is generated by deleting the extracted destination of the printer 200. That is, as shown in FIG. 16, the printer 100 deletes the information about the printer 200 from the destination information shown in FIG. 15, and the destination of the information processing apparatus 300 that is the transmission source of the PDL data and the transmission destination of the PDL data Destination information in which a list of destinations of the printer 400 to which the PDL data is to be transferred and a transfer priority order of the destinations of the printer 400 is described is generated.

  In step S54, the printer 100 adds the generated destination information to the PDL data stored in the storage unit 101 under the control of the transfer control unit 102, and this data is the destination extracted in step S53. Transfer to a certain printer 200.

  In the image forming system, when the PDL data to which the destination information is added is transmitted from the printer 100 in this way, the printer 200 transmits the destination transmitted from the printer 100 in step S61 as shown in FIG. The PDL data to which the information is added is received via the NIC unit 203, the data is stored in the storage unit 201, and the PDL data is converted into image data in a format that can be formed by the image conversion unit 204. The image forming unit 205 forms an image based on the converted image data.

  Subsequently, when the image forming process is completed in step S62, the printer 200 has the highest priority based on the destination information received from the printer 100 under the control of the transfer control unit 202 in step S63. The destination of the printer 400 is extracted, and new destination information is generated by deleting the destination of the extracted printer 400. That is, as shown in FIG. 17, the printer 200 deletes information related to the printer 400 from the destination information shown in FIG. 16, and uses destination information that describes only the destination of the information processing apparatus 300 that is the transmission source of PDL data. Generate.

  In step S64, the printer 200 adds the generated destination information to the PDL data stored in the storage unit 201 under the control of the transfer control unit 202, and this data is the destination extracted in step S63. Transfer to a certain printer 400.

  Similarly, in the image forming system, when the PDL data to which the destination information is added is transmitted from the printer 200 in this way, the printer 400 transmits from the printer 200 in step S71 as shown in FIG. The PDL data to which the destination information is added is received via the NIC unit 403, the data is stored in the storage unit 401, and the PDL data is converted into image data in a format that can be formed by the image conversion unit 404. After the conversion, image formation by the image forming unit 405 is performed based on the converted image data.

Try to extract. Here, since information of another printer is not registered in the destination information, the printer 400 selects the information processing apparatus 300 that is the transmission source as the next transfer destination based on the destination information.

  In step S74, the printer 400 transfers the PDL data stored in the storage unit 401 to the information processing apparatus 300 under the control of the transfer control unit 402, and ends the series of processes. Note that the printer 400 may end the series of processes as it is without transferring the PDL data to the information processing apparatus 300.

  As described above, in the image forming system, the destination information is added to the PDL data to which the destination information is added and sequentially transferred to perform circulation-type communication.

  As described above, in the image forming system shown as the second embodiment of the present invention, new destination information is generated based on the destination information received by each printer, and this destination information is transmitted together with the PDL data.

Alternatively, the fact that the transfer of the PDL data has been completed is notified by printing. When the display and / or printing ends, the information processing apparatus 300 deletes the PDL data and the accompanying information stored in the storage unit, and ends the series of processes.

  In the image forming system, when the printer 100, 200, 400 rather than the information processing apparatus 300 is the transmission source of the PDL data, the printer 100, 200, 400 stores the transmitted PDL data in the storage unit 101, 201 and 401, and by comparing the PDL data with the received PDL data under the control of the transfer control units 102, 202, and 402, the data transfer is performed based on the comparison result. You may make it recognize whether it completed normally.

  As described above, in the image forming system shown as the third embodiment of the present invention, the transmitted PDL data is stored in the storage unit by each of the information processing apparatus 300 or the printers 100, 200, and 400. By comparing the PDL data with the received PDL data, it is possible to recognize whether or not the data transfer is normally completed based on the comparison result. Therefore, in this image forming system, it is possible to appropriately transfer data.

  Finally, an image forming system shown as the fourth embodiment will be described.

  The image forming system shown as the fourth embodiment is an improvement of the image forming system shown as the third embodiment, and adds unique information for specifying PDL data to destination information. Therefore, in the description of the fourth embodiment, the same components as those in the description of the third embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
