Description

  The present invention relates to an image forming system, an image forming apparatus, and a program.

  In a certain system, the transmission side transmits divided data of certain data in duplicate in at least two of the plurality of communication lines, and the receiving side restores the original data when receiving the divided data ( For example, see Patent Document 1). Thereby, even if a reception error occurs due to a failure in a certain communication line, the receiving side can receive all the divided data and can restore the original data. In another system, when a failure occurs in a certain communication line, divided data to be transmitted on the communication line is transmitted on another communication line (see, for example, Patent Document 1).

  After the host device 2 is activated, various programs are appropriately executed by the arithmetic processing unit 44. In the first embodiment, the arithmetic processing unit 44 uses an operating system (not shown), a SOAP interface processing unit 61, a facsimile interface processing unit 62, an HTTP interface processing unit 63, an email interface processing unit 64, a local interface processing unit 65, And the driver 66 is realized.

  The divided print data obtained by dividing the print data for one print job is transmitted by the interface processing units 61 to 65.

  The driver 66 is a processing unit realized by executing the driver program 51 in the storage device 43 in the arithmetic processing unit 44, and receives the above-described use interface information in any of the interface processing units 61 to 65. Then, one print data is divided into a plurality of divided print data at a transmission amount ratio based on the received use interface information, and the divided print data is sent to the image forming apparatus 1 using the plurality of interface processing units 61 to 65. Send.

  In the first embodiment, when the driver 66 receives the above-described retry request, the driver 66 transmits the rest of the print data according to the retry request using the interface processing units 61 to 65.

  Note that the driver 66 generates print data such as PDL data from original data generated by an application (not shown).

  Further, a USB memory (not shown) may be connectable to the USB interfaces 12 and 42. In that case, the divided print data is transmitted using the USB memory as a medium. That is, the divided print data is stored in the USB memory in the host device 2, the user carries the USB memory from the host device 2 to the image forming apparatus 1, and the divided print data is read from the USB memory in the image forming apparatus 1. . In this case, transmission by USB memory is one interface method. In this way, when divided print data is transmitted using a USB memory, a print job is not started until the user connects the USB memory to the image forming apparatus 1, thereby preventing unintentional security leakage from the printed matter due to the print job. it can.

  Next, the operation of each device in the system will be described. FIG. 2 is a sequence diagram for explaining the operations of the image forming apparatus 1 and the host apparatus 2 in the system shown in FIG.

  When a print request is generated by a user operation or the like in the host apparatus 2 (step S1), the driver 66 transmits a use interface information transmission request to the image forming apparatus 1 using any of the interface processing units 61 to 65. (Step S2).

  In the image forming apparatus 1, when the job management unit 36 receives the transmission request by any one of the interface processing units 31 to 35, the log data 22 is read, and use interface information is generated based on the log data 22 ( Step S3).

  Specifically, the job management unit 36 does not use an interface method in which a reception error (or a reception amount ratio of 0%) is recorded in the log data 22, and specifies a specific transmission for the remaining interface method to be used. Determine the volume proportion.

  For example, based on the default transmission amount ratio, the transmission amount ratio of the unused interface method is determined by being distributed to other interface methods. For example, the distribution method is a method of distributing evenly.

  FIG. 3 is a diagram illustrating an example of a default transmission amount ratio for each interface method set in the image forming apparatus 1 in FIG.

  In FIG. 3, “HTTP” indicates an HTTP interface, “SOAP” indicates a SOAP interface, “POP3” indicates an e-mail interface, “FAX” indicates a facsimile interface, and “Local USB” indicates “Local USB”. “USB memory” indicates an interface method using a USB memory.

  In FIG. 3, for example, the default transmission rate ratio of “HTTP” is 15%, and the size of the divided print data for the HTTP interface is 15% of the size of the print data.

  When the usage interface information is generated in this way, the job management unit 36 transmits the usage interface information to the host device 2 by any of the interface processing units 31 to 35 (step S4).

  In the host device 2, when the driver 66 receives the use interface information in any of the interface processing units 61 to 65, the driver 66 generates print data, and the print data is transmitted at a transmission amount ratio specified by the use interface information. Is divided (step S5).

  Then, the driver 66 transmits the divided print data corresponding to each interface processing unit by the interface processing unit (step S6).

  At this time, if there is no communication failure in the transmission of all the divided print data, all the divided print data are received by the image forming apparatus 1. When the interface processing units 31 to 35 receive all the divided print data, the job management unit 36 restores the original print data, supplies the print data to the RIP unit 15, and executes printing.

  For example, the divided print data includes an identifier indicating the divided print data, the number of divided print data generated by the division, the order of the divided print data, and the like, and based on the information, the original print Data is restored. Further, the job management unit 36 may determine whether the print data is divided print data from the data structure of the divided print data, or may cause the RIP unit 15 to process the divided print data, and from the processing result, You may make it determine whether it is division | segmentation print data.

  On the other hand, when a reception error occurs for one or a plurality of divided print data (step S7), the job management unit 36 generates a retry request and sends it to the driver 66 of the host apparatus 2 using an interface method in which no reception error has occurred. Transmit (step S8).

  At this time, for example, it is determined that a reception error has occurred for the divided print data that has not been received within a specific time from the time when the used interface information is transmitted or the first divided print data is received.

  The retry request includes the interface method in which the reception error has occurred or the order of the divided print data in which the reception error has occurred, the interface method to which the divided print data is distributed, and the transmission amount ratio of the interface method.

  When the driver 66 of the host device 2 receives the retry request, the driver 66 identifies the divided print data in which a reception error has occurred from the retry request, further divides the divided print data, and receives the divided print data that has been divided again. Transmission is performed by an interface method in which no error has occurred (step S10).

  When the job management unit 36 receives the divided print data, the job management unit 36 restores the original divided print data and confirms that all the divided print data has been received (step S11). The reception amount ratios 31 to 36 are calculated, and the reception amount ratio and the presence or absence of reception errors are recorded in the log data 22 (step S12).

  Further, the job management unit 36 restores the original print data from all the divided print data, supplies the print data to the RIP unit 15, and executes printing (step S13).

  FIG. 4 is a diagram showing an example of the log data 22 when a reception error occurs in the system shown in FIG. 4A shows the presence / absence of a reception error and the reception amount ratio for each interface method in the log data 22, and FIG. 4B shows the interface method in which the reception error has occurred in the log data 22. Shows the error count and details of the error.

  For example, when print data is transmitted at the default transmission amount ratio shown in FIG. 3 and a reception error occurs in “POP3” and “FAX” as shown in FIG. 4A, the transmission amount ratio of “POP3” 15 % And “FAX” transmission amount ratio 15% are distributed to “HTTP”, “SOAP” and “Local USB”, and as a result, the reception amount ratio of “HTTP” is 27% (= 15% + 12%) Thus, the reception amount ratio of “SOAP” is 27% (= 15% + 10%), and the reception amount ratio of “local USB” is 38% (= 30% + 8%). That is, the divided print data “POP3” and “FAX” are further divided and transmitted by “HTTP”, “SOAP”, and “local USB”.

  After that, when receiving a use interface information transmission request, the job management unit 36 makes “POP3” and “FAX” unused based on the presence / absence of the reception error and the received amount ratio shown in FIG. Use interface information with the transmission amount ratio of “HTTP”, “SOAP”, “local USB”, and “USB memory” set to 30%, 30%, 30%, and 10% is transmitted.

  As a result, since the interface method in which the reception error occurred last time is not used, there is a high possibility that no reception error will occur.

  FIG. 5 is a diagram showing an example of the log data 22 in the case where no reception error has occurred in the system shown in FIG.

  If no reception error occurs, the transmission amount ratio of “HTTP”, “SOAP”, “Local USB”, and “USB memory” is specified as 30%, 30%, 30%, 10% according to the use interface information. In this case, as shown in FIG. 5, the divided print data is received at the same reception amount ratio.

  As described above, in the first embodiment, the job management unit 36 of the image forming apparatus 1 records the received amount ratio of the print data for each interface method as the log data 22 and transmits the next print data. From the received amount ratio in the log data 22, use interface information indicating a print data transmission amount ratio for each interface method is generated and transmitted to the host device 2. Then, the driver 66 of the host device 2 receives the use interface information, and uses the plurality of interface processing units 61 to 65 to generate the divided print data divided by the transmission amount ratio based on the received use interface information. Transmit to forming apparatus 1.

  Accordingly, the transmission amount ratio of each interface method for the transmission of the current print data is determined from the reception amount ratio in the log data 22 regarding the transmission of the past print data from the host apparatus 2 to the image forming apparatus 1. The interface method having a communication failure specified from the reception amount ratio of the log data 22 does not have to be used for transmission of the print data this time. Therefore, an increase in data transmission time and an increase in downtime due to communication failure when data is divided and transmitted are reduced.

Embodiment 2. FIG.

  In the second embodiment, the driver 66 of the host device 2 records the print data transmission amount ratio for each interface method in the storage device 43 as log data. Then, the driver 66 specifies the transmission amount ratio of the print data for each interface method for the print data to be transmitted this time from the transmission amount ratio in the log data, and the divided print data divided by the transmission amount ratio is The image is transmitted to the image forming apparatus 1 using the plurality of interface processing units 61 to 65.

  In the second embodiment, when a transmission error occurs in any of the interface methods for the divided print data, the driver 66 uses the remaining print data to be transmitted in the interface method in which the transmission error has occurred for the divided print data. Transmit using the interface method that does not cause a transmission error. Then, after the transmission of all the divided print data is completed, the driver 66 records the transmission amount ratio for each interface method as log data.

  In the second embodiment, the driver 66 continuously disables the interface method in which the transmission error has occurred. However, the driver 66 resumes the use of the interface method when the setting change of the interface processing unit of the interface method that is continuously unused is detected. That is, the transmission rate ratio of the interface method is set to a non-zero value.

  Since the other configurations and operations of the image forming apparatus 1 and the host apparatus 2 in the second embodiment are the same as those in the first embodiment, description thereof is omitted.

  As described above, in the second embodiment, the driver 66 of the host apparatus 2 records the print data transmission rate for each interface method as log data, and prints to be transmitted this time based on the transmission rate in the log data. A transmission amount ratio of print data for each interface method for data is specified, and divided print data divided by the transmission amount ratio is transmitted to the image forming apparatus 1 using a plurality of interface processing units 61 to 65.

  As a result, the transmission amount ratio of each interface method for the current print data transmission is determined from the transmission amount ratio in the log data for the past print data transmission from the host apparatus 2 to the image forming apparatus 1. The interface method with a communication failure specified from the log data transmission rate ratio does not have to be used for the current print data transmission. Therefore, an increase in data transmission time and an increase in downtime due to communication failure when data is divided and transmitted are reduced.
