Next, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an image forming system according to an embodiment of the present invention.

As shown in FIG. 1, the image forming system of one embodiment of the present invention is composed of three printing systems 40A to 40C connected to each other by a network 30.
Here, it is assumed that the printing systems 40A and 40B have the same model, the model name is "ABCD", and the printing system 40C has the model name "XYZ".

The printing system 40A is composed of a commercial printing device 20A and a controller 10A for controlling the printing processing operation of the printing device 20A. Similarly, the printing system 40B is composed of a commercial printing device 20B and a controller 10B for controlling the printing processing operation of the printing device 20B, and the printing system 40C is composed of a commercial printing device 20C and the commercial printing device 20C. It is composed of a controller 10C for controlling the printing processing operation of the printing apparatus 20C.

The controllers 10A and 10B are print control devices in which driver software for controlling the print processing operation of the printing devices 20A and 20B of the model "ABCD" is installed, respectively, and are referred to as the controllers 10C and "XYZ". This is a print control device in which driver software for controlling the print processing operation of the model print device 20C is installed. Here, the controllers 10A to 10C may be referred to as a DFE (Digital Front End).

Since the version of such driver software is changed by being updated, the version of the driver software for the same model may be different. Here, the driver software of version 1.0 (indicated as Ver.1.0 in the drawing) is installed in the controller 10A, and version 2.0 (indicated as Ver.2.0 in the drawing) is installed in the controller 10B. It is assumed that the driver software of is installed. Further, it is assumed that the driver software of version 1.0 for controlling the printing device 20C of the model "XYZ" is installed in the controller 10C.

The controllers 10A to 10C are connected to each other via the network 30, and the address information for identifying each device on the network 30 is "192.168.1.1", "192.168.1.2", or "192.168". It is assumed that the IP (Internet Protocol) address ".1.3" is set.

Here, in the printing systems 40A to 40C as described above, the printing process is performed using various printing resources. Here, the print resource includes various data used when executing the print process, is at least a part of the print data for executing the print process, and even when the print resource itself becomes the print data. is there. In some cases, a plurality of print resources are associated with the print data. When multiple print resources correspond to the print data, the verification method and save method of each print resource may be changed according to each type of the plurality of print resources, and the priority is given. Depending on the print resource, the verification method and the storage method of the print data associated with the print resource may be changed.

A specific example of such a print resource is shown in FIG.

Referring to FIG. 2, the print resource includes, for example, various setting information such as system setting, imposition setting, color setting, and stock setting. Here, the system setting is setting information that differs depending on the user environment of the controller. Further, the imposition setting is setting information related to imposition processing in which printing results for a plurality of pages are included in one physical sheet at the time of printing, and is information that does not depend on the printing device. Further, the color setting is setting information regarding colors at the time of printing, such as LUT (abbreviation of Look Up Table) and ICC (abbreviation of International Color Consortium) profile.

The print resource also includes data used when actually printing an image on paper, such as watermark data, form data, template data, resource set data, and font data.

Further, the print resource also includes setting information related to the print data type setting, which is a setting different for each print data type of the controller.

Then, the controllers 10A to 10C in each of the printing systems 40A to 40C perform printing control using such printing resources.

Here, in the printing process for business use, the number of sheets to be printed may be enormous, and the printing process of the same content may be performed periodically. Therefore, in the controllers 10A to 10C, the print resource is not deleted only by performing the print process once, but the print resource is backed up and reused.

Further, the print resource backed up in any of the controllers 10A to 10C may be used in the other controller to execute the print process.

However, in each printing system 40A to 40C, the model and the version of the driver software installed in the controllers 10A to 10C may be different. Therefore, a print resource that can execute a normal print process in a certain printing system may not be able to execute a normal print process in another print system, and an error may occur.

In addition, for printing resources such as special font data that cannot be used without special license information, even if the same model and the same version of driver software is installed on the controller, some printing systems process printing. However, it may happen that the printing process cannot be executed by other printing systems.

Fig. 3 and Fig. 3 show an example of a pattern in which an error occurs when the print resource backed up and saved by a certain controller is restored on the controller of the own device or another device and an error occurs. This will be described with reference to 4.

In the following description, a case where a certain print resource is backed up in the controller 10A and the print resource is restored and used will be described.

For example, in FIG. 3, in the controller 10A having the model name "ABCD" and the software version 1.0, after backing up a certain print resource, the software update is performed in the controller 10A, and the software version is updated to 2.0. The case where it is done is shown as an example. In this case, if the backed up print resource is restored to the controller 10A with the model name "ABCD" and the software version 2.0 and the print process is executed, an error may occur. ..

Further, in FIG. 3, the print resources backed up in the controller 10A having the model name “ABCD” and the software version 1.0 are restored to the controller 10B having the same model and the same version, and the printing process is executed. It has been shown that an error may occur when trying. In this case, for example, special font data in the print resource is included, and the controller 10A stores the license information for using the font data, but the controller 10B has such a license. The cause is that the information is not stored.

Further, in FIG. 4, the print resource backed up in the controller 10A having the model name “ABCD” and the software version 1.0 is restored to the controller 10C having the same model and the same version, and the printing process is executed. It has been shown that an error may occur when trying.

Further, in FIG. 4, the print resources backed up in the controller 10A having the model name “ABCD” and the software version 1.0 are restored to the controller 10C which is another model and the different version, and the printing process is executed. It has been shown that an error may occur when trying.

In this way, even if the print resource was able to execute the print process normally on the controller 10A, if it is restored and used on another controller 10B, 10C, or the controller 10A with a different software version, an error occurs and it is normal. Printing process may not be possible.

Therefore, in the image forming system of the present embodiment, when backing up the print resources in the controllers 10A to 10C, it is verified whether or not the print process can be normally executed when the print resources are restored and used. I try to save it after doing it.

Specifically, as shown in FIG. 5, when backing up a certain print resource in the controller 10A, the print resource is verified in the own device, or a verification request is made to the controllers 10B and 10C which are other devices. Is performed, and after receiving the verification result, it is stored. Here, even when the controller 10A performs verification in its own device, a process of formally making a verification request to its own device and receiving a verification result from its own device is executed.

Here, the device for making the verification request is expressed as the verification destination device, and when the verification destination device is the controller 10B, the verification request is transmitted and the verification result is returned, as shown in FIG.

Referring to FIG. 6, the verification request source controller 10A transmits a verification request to the controller 10B via the network 30, verification is performed by the controller 10B that receives the verification request, and the verification result is the controller 10B. Is shown to reply to the controller 10A.

Further, FIG. 7 shows how the verification request is transmitted and the verification result is returned when the verification destination device is the own device.

Referring to FIG. 7, when the controller 10A of the verification request source sends a verification request to the controller 10A which is the own device, the controller 10A performs the verification and the verification result is returned to the own device. .. In this case, when viewed from the outside, the print resource to be backed up is verified in the controller 10A.

Next, FIG. 8 shows the hardware configuration of the controller 10 in the image forming system of the present embodiment. In the following description, when each of the controllers 10A to 10C is expressed without being specified, the controller 10 is expressed without an alphabet.

As shown in FIG. 8, the controller 10 is a communication interface (with IF) that transmits and receives data to and from an external device and the like via a CPU 11, a memory 12, a storage device 13 such as a hard disk drive, and a network 30. It has a user interface (abbreviated as UI) device 15 including a touch panel or a liquid crystal display and a keyboard. These components are connected to each other via a control bus 16.

The CPU 11 executes a predetermined process based on the control program stored in the memory 12 or the storage device 13 to control the operation of the controller 10. In the present embodiment, the CPU 11 is described as reading and executing the control program stored in the memory 12 or the storage device 13, but the program is stored in a storage medium such as a CD-ROM and stored in the CPU 11. It is also possible to provide.

FIG. 9 is a block diagram showing a functional configuration of the controller 10 realized by executing the above control program.

As shown in FIG. 9, the controller 10 of the present embodiment includes an operation reception unit 31, a display control unit 32, a data transmission / reception unit 33, a print control unit 34, a backup processing control unit 35, and a management table storage. A unit 36 and a backup data storage unit 37 are provided.

The display control unit 32 controls to display various information to the user. The operation reception unit 31 inputs various operation information performed by the user. When the print resource is backed up, the operation reception unit 31 receives an instruction to back up the print resource.

The data transmission / reception unit 33 transmits / receives data to / from another controller 10 via the network 30. The data transmission / reception unit 33 also transmits / receives data to / from the printing device 20.

The print control unit 34 controls the connected printing device 20 to execute the print process.

The management table storage unit 36 is a verification method for verifying whether or not the print process can be normally executed when the print process using a certain print resource is executed, and a device for executing the verification. The destination information of the destination device is stored according to the type of print resource.

In the management table storage unit 36, the verification method and the destination information of the verification destination according to the type of the print resource are stored as the verification destination / verification method table. An example of this verification destination / verification method table is shown in FIG.

In the verification destination / verification method table shown in FIG. 10, the type of print resource, the address information of the verification destination device as the destination information of the verification destination, and the verification method are associated with each other. For example, for font data among the types of print resources, the address information of the verification destination device is an IP address of 192.168.1.1, and as the verification method, a verification method A for performing raster comparison and a verification method B for performing an interpreter. Is associated with.

Similarly, in this verification destination / verification method table, a verification method B that performs an interpreter is associated with the verification method of print resources such as form data and watermark data. Further, as a verification method of print resources such as color setting information, ICC profile data, and LUT, a verification method C of performing binary comparison is associated. The printing resource verification method is not limited to the verification method illustrated above, and various verification methods can be used.

Here, the verification method A for performing raster comparison is to print the raster data by converting the raster data into raster data using the print resource and comparing the raster data with the raster data which is known to be correct in advance. This is a verification method that confirms that the printing process using resources is executed correctly.

Further, the verification method B for performing an interpreter is a verification method for confirming that an error or the like does not occur by expanding a print job described in a page description language using the print resource.

When the device to be verified is the controller 10A, the IP address of 192.168.1.1 is the address information of the own device. Therefore, when verifying the font data, the device to be verified is referred to the own device. A verification request will be made.

The backup process control unit 35 verifies whether or not the print process can be normally executed when the print process using the print resource is executed when the instruction to back up the print resource is received. The verification method of is specified according to the type of print data that has received the backup instruction. Specifically, the backup processing control unit 35 refers to the verification destination / verification method table as shown in FIG. 10 stored in the management table storage unit 36, and the verification method corresponding to the type of the print resource. Is specified from multiple verification methods.

Further, the backup processing control unit 35 specifies the destination information of the verification destination device, which is the device that executes the verification, according to the type of the print resource that has received the backup instruction by the same method.

Here, the backup processing control unit 35 holds the license information when the license information permitting the use of the print resource of the specific type is required to execute the print process using the print resource of the specific type. The destination information of the verification destination device is specified as the destination information of the verification destination device according to the type of print resource that has received the backup instruction. For example, when the backup processing control unit 35 needs license information for using the font data in order to use the specific font data, the backup processing control unit 35 serves as a verification destination device for verifying the specific font data. The device that stores the license information is specified as the verification destination device.

Then, the backup processing control unit 35 uses the destination information of the specified verification destination device to transmit the print resource that has received the backup instruction to the verification destination device via the data transmission / reception unit 33.

Then, when the backup processing control unit 35 transmits the print resource to the verification destination device and requests the verification, the information of the print resource for which the verification request is made is the verification requested list as shown in FIG. Register with. This verification requested list is stored in the management table storage unit 36, and the type, name, verification request status, and verification result of the verified print resource are stored in association with each other.

When the verification result that the print processing can be executed normally is returned from the verification destination device that has transmitted the print resource, the backup processing control unit 35 has not verified the verification result of the above verification requested list. The print resource that has received the backup instruction is saved in the backup data storage unit 37.

At that time, the backup processing control unit 35 saves the print resource that has received the backup instruction together with the verification result for the print resource. The save destination of the print resource does not have to be in the own controller, and may be saved in an external server or the like.

This verification result includes information on the model name of the verification destination device that has been verified and information on the version of the software being executed on the verification destination device.

The backup processing control unit 35 saves the print resource that has received the backup instruction when the verification result that the print processing can be normally executed cannot be obtained from the verification destination device that has sent the print resource. do not do.

In this way, the backup processing control unit 35 stores the print resource whose verification has been executed by using the specified verification method in the backup data storage unit 37.

The backup data storage unit 37 stores the print resource instructed to back up together with the verification result as described above.

FIG. 12 shows an example of print resources backed up in the backup data storage unit 37. With reference to FIG. 12, it can be seen that the backed up print resource is stored together with information on the type, name, verification result, verification execution model, and verification execution software version of the print resource.

If the backup processing control unit 35 has a plurality of verification destination devices according to the type of print resource that has received the backup instruction, the backup processing control unit 35 divides the print resource that has received the backup instruction into the plurality of verification destination devices. You may send to each of them.

Further, when the destination information of the specified verification destination device is the address information of the own device, the backup processing control unit 35 verifies the print resource that has received the backup instruction on the own device. At that time, the backup processing control unit 35 executes the verification of the print resource that has received the backup instruction by itself.

Next, the operation of the controller 10 of the present embodiment will be described in detail with reference to the drawings.

First, the overall operation of the controller 10 in this embodiment will be described with reference to the flowchart of FIG.

When an instruction to back up a certain print resource is received, the backup processing control unit 35 performs a temporary backup in step S101 to temporarily store the print resource in the backup data storage unit 37.

Then, in step S102, the backup processing control unit 35 acquires information on the type of print resource for which the backup instruction has been given.

Then, in step S103, the backup processing control unit 35 determines whether or not verification of the print resource is necessary. If verification of the print resource is not required in step S103, the backup processing control unit 35 officially stores the print resource as backup data in the backup data storage unit 37.

Then, when verification of the print resource is required in step S103, the backup processing control unit 35 executes a verification request for the print resource in step S104.

Then, when the verification is completed in the verification destination device for which the verification request has been made and the verification result is returned, the backup processing control unit 35 confirms the verification result in step S105.

Finally, in step S106, the backup processing control unit 35 executes the backup processing of the print resource according to the content of the confirmed verification result.

Specifically, the backup processing control unit 35 receives the backup instruction when the verification result that the print processing can be normally executed when the print resource is used is obtained. Is saved in the backup data storage unit 37, and if the verification result that the print process can be executed normally when the print resource is used is not obtained, the print resource that has received the backup instruction is not saved. ..

Next, the verification request execution process of step S104 described in the flowchart of FIG. 13 will be described in detail with reference to the flowchart of FIG.

When executing the verification request, the backup processing control unit 35 first acquires a verification method according to the type of print resource in step S201. Specifically, the backup processing control unit 35 specifies a verification method according to the type of print resource to be backed up from the verification destination / verification method table as shown in FIG.

Next, in step S202, the backup processing control unit 35 acquires the address information of the verification destination device according to the type of print resource. Specifically, the backup processing control unit 35 acquires the IP address of the verification destination device according to the type of the print resource to be backed up from the verification destination / verification method table as shown in FIG.

Then, in step S203, the backup processing control unit 35 transmits the print resource to be verified to the verification destination device using the acquired address information, and makes a verification request.

After that, in step S204, the backup processing control unit 35 adds the information of the print resource for which the verification request has been made to the verification requested list shown in FIG.

Finally, in step S205, the backup processing control unit 35 determines whether or not there is another print resource for which verification should be requested. The backup processing control unit 35 repeats the processes of steps S201 to S204 when there is another print resource for which verification should be requested, and ends the verification request execution process if it does not exist.

Next, the verification result confirmation process of step S105 described in the flowchart of FIG. 13 will be described in detail with reference to the flowchart of FIG.

When the verification result is returned from the verification destination device that has made the verification request, the backup processing control unit 35 acquires the verification result in step S301.

Then, in step S302, the backup processing control unit 35 normally prints whether or not the acquired verification result has no problem, that is, when the print process using the print resource for which the verification request has been requested is executed. Determine if it is executed.

If there is no problem with this verification result, the backup processing control unit 35 deletes the information of the print resource from the verification requested list in step S303.

Then, in step S305, the backup processing control unit 35 determines whether or not there is another print resource for which the verification result has not been acquired among the print resources for which verification has been requested. The backup processing control unit 35 returns to the process of step S301 when there is another print resource for which the verification result should be acquired, and ends the verification result confirmation process if it does not exist.

If there is a problem with the acquired verification result in step S302, the backup processing control unit 35 executes the correction process of the print resource in step S304. In this case, the backup processing control unit 35 may re-execute the correction request for the corrected print resource.

Finally, the processing in the verification destination device that has received the verification request from the other device will be described in detail with reference to the flowchart of FIG.

When a verification request is transmitted from one controller 10 to another controller 10, the backup processing control unit 35 in the other controller 10 receives the verification request in step S401.

Then, in step S402, the backup processing control unit 35 acquires the print resource to be verified from the received verification request. Then, in step S403, the backup processing control unit 35 executes the verification process for the acquired print resource to be verified.

The backup processing control unit 35 determines whether or not the next print resource to be verified exists in step S404, and if so, repeats the processes of steps S402 and S403.

Then, when the next print resource to be verified does not exist in step S404, the backup processing control unit 35 determines in step S405 whether or not the next verification request exists.

Here, when the next verification request exists, the backup processing control unit 35 repeats the processing of steps S401 to S404.

Then, when it is determined in step S405 that the next verification request does not exist, the backup processing control unit 35 returns the verification result to the device that has made the verification request in step S406.
