Abstract

A billing process for a printing process on a network is efficiently performed. A client transmits a print request file and a form file to a charging server. The accounting server 100 transmits to the client 102 a print permission file 110 describing the permitted amount of resources such as the number of available print papers. The billing server creates billing information based on the resource amount and stores the billing information in the billing information file 108. The client 102 transmits the print permission file 110 to the printer 112 prior to the form file. The printer device 112 executes the printing process only when the print permission file 110 is transmitted prior to the form file 104. The accounting information can be centrally managed, and printing can be controlled efficiently.

2. Description of the Related Art When printing a form or the like on a network, the print requests are once collected by a print server or the like, and the print server performs a predetermined spooling process or the like, and appropriately sends the request to a printer on the network. Data to be printed was sent out.

As described above, when printing a form or the like,
It is often necessary to charge for each print process. This billing is often performed by a print spooler in the print server. That is, since the print spooler actually holds the file to be printed, the number of prints and the like can be relatively easily known. Therefore, it is preferable that the calculation of the billing amount is also performed by the print spooler. Such a conventional charging operation will be described below with reference to FIG.

FIG. 12 is an explanatory diagram showing a conventional printing process on a network and a charging operation for the printing process.

As shown in FIG. 12, conventionally, a client 10 requesting a print sends a print request to a print server 12. The print server 12 appropriately spools a print request from the client 10 using the print spooler 12a. The print spooler 12a accumulates billing information for each user by counting the number of pages of a form to be billed. This charge information is stored in the charge information file 1 in the print server 12.
4 was stored.

Preferred embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 FIG. 1 is a configuration diagram of a network system according to a preferred embodiment of the present invention. As shown in this figure, a feature of the first embodiment is that a billing server 100 independent of the print server is provided.

First, a client program or a batch program (hereinafter, referred to as a print client 102) that prints a form or the like sends a print request to the charging server 10 before sending it to a print server or the like.
For 0, a form file 104 to be printed and accounting information 106 such as the number of printed pages are notified. The transmission of the accounting information 106 and the form file 104 is indicated by (1) in FIG.

Next, the accounting server 100 stores the transmitted accounting information 106 in the accounting information file 108. This accumulation operation is indicated by (2) in FIG.
The billing server 100, together with the storage operation, performs the billing information 1
A print permission file 110 is generated based on the print permission file 06 and the form file 104. The operation of generating the print permission file 110 is indicated by (3) in FIG. Then, the accounting server 100 transmits the print permission file 110 to the print client 102.

The print permission file 110 defines resources (called resources) that can be used, such as the number of print permitted pages, and a form for uniquely recognizing data of the form file 104 to be printed. This is the file containing the recognition key.

The print client 102 transmits the transmitted print permission file 110 and the form file 104 to be printed to the printer 112 connected to the network. Specifically, when the print client 102 transmits the print permission file 110 to the printer device 112, the print client 102 transmits the form file 104 to the printer device 112 following the transmission. This transmission operation is indicated by (4) in FIG.

The printer device 112 has a function of rejecting a print request when only the form file 104 is transmitted without accompanying the print permission file 110. Further, when the form file 104 is transmitted following the print permission file 110, the printer device 112 first transmits the form file 104 using the form recognition key described in the print permission file 110. The form file 104 is the print permission file 110
Check if the file is allowed by.
More specifically, the form recognition key described in the print permission file 110 is continuously transmitted to the form file 104.
A check is performed to determine whether or not the ID is uniquely recognized.

As a result of this inspection, if the form file 104 can be uniquely identified and it can be confirmed that the printing permission has been obtained, the printer device 112 starts printing the form file 104.

Further, the printer device 112 constantly monitors the number of printed pages during the printing process. If printing is performed beyond the number of print-permitted pages described in the print-permitted file 110, the printing is stopped.

As described above, according to the present embodiment, accounting management for form printing can be easily performed even in a distributed system in which a plurality of servers and clients and a network printer are installed. Note that the printer 112 according to the present embodiment has a function as a print server. In the present embodiment,
The printer device 112 has a function as a print server. For example, the print permission file 110 is stored in a local area network board or a printer adapter for connecting the printer device to a local area network.
It is also preferable to provide a check function of As described above, if the local area network board or the printer adapter is provided with the function of checking the print permission file 110, it is possible to use a conventional printer that is not compatible with the network.

According to the present embodiment, the print server (the printer 112 in the present embodiment) and the printer connected via the printer adapter need to be provided with a charge management function for each user. Disappears. Further, when the number of users increases, if the addition of the user is set only in the charging server 100, the charging is automatically performed, so that the operation of the system can be facilitated.

The printer 112 according to the present embodiment merely checks the print permission file 110 without depending on the user or the system configuration. For this reason, it is possible to easily make settings when adding the printer device 112 to the network system.

The billing method proposed in the present embodiment uses a billing server 100 for billing when printing a form.
Is calculated with However, the aggregation of such charges is
The present invention can be applied not only to print processing but also to all services using resources on a network. For example, a similar server can be used when performing accounting management for resource amounts such as communication amounts when transferring files. As the communication amount, it is conceivable to charge the file transfer using, for example, the number of bytes of the transmitted data, the time required for the communication, and the like.

Embodiment 2 Embodiment 2 is an embodiment showing a basic idea of the present invention, and an explanatory diagram thereof is shown in FIG.

As shown in FIG. 2, in this embodiment, the business client X1 and the print server Y
1 and a billing server 100 are connected via a local area network 200. That is, the business client X1, the print server Y1, and the billing server 100 each have an interface for connecting to the local area network 200. This interface corresponds to the connection means of the present invention.

First, the business client X1 that performs printing
Notifies the accounting server 100 of a print request file 202 in which a request for resources required for printing, such as the number of print sheets, is recorded, and a print data file 204.

This notification operation is shown by (1) in FIG.

As described above, the printing permission is requested by notifying the print request file 202 and the print data file 204 to the accounting server 100. The contents of the print request file 202 can be various print parameters such as the size of the print data file 204 and the execution time of the print processing, as well as the number of print sheets. still,
In the present embodiment, the case where the business client X1 requests printing is described. However, the same applies to a case where printing is requested by a business program or predetermined batch processing.

When the print request file 202 and the print data file 204 are transmitted, the billing server 100 recognizes the amount of available resources such as the number of print sheets recorded in the print request file 202 and the print data recognition. A print permission file 110 including a key is generated. The print permission file 110 is generated by the print permission file generation processing unit 206.

Here, the amount of resources that can be used means parameters such as the number of sheets permitted for printing, and the print data recognition key uniquely identifies the print data file 204 to be printed. The key that can be.

Specifically, the print data identification key is preferably a key determined from the contents of the print data file 204. This key is calculated by performing a predetermined operation on the contents, but more simply, it is preferable to use the address in the print data file 204 and the value at that address as the key. The print data identification key is stored in the print data file 204.
It is also preferable to include the creation date and time. Further, the print data identification key may include a key specified from the above contents of the print data file 204 and a plurality of types of keys such as a creation date and time. By combining a plurality of types of keys, the print data file 204 can be identified more accurately.

When the print permission file 110 is returned from the accounting server 100 to the business client X1, printing permission is given.

FIG. 3 is an explanatory diagram showing the structure of the print permission file 110. As shown in this figure, the print permission file 110 includes a print data file name and a print data identification key. Further, the print permission file 110 includes a repetition of a pair of a resource ID and a permitted amount used for printing. In the text, this repetition is called print permission information. The resource ID is an ID for identifying a resource, and the resource name is used for simplicity (see FIG. 3).

The accounting server 100 records, in the accounting information log file 208, the amount of usable (permitted to use) resources, such as the number of print sheets, for the user who has been permitted to print. That is, charging information for the resource amount permitted to be used is recorded in the charging information log file 208. The recording of the billing information in the billing information log file 208 is indicated by (3) in FIG.

The writing to the accounting information log file 208 is performed in accounting log record units. In addition, it is preferable that the log record generally includes the name of the user who has requested the printing, in order to clarify the billing target person. Each billing log record includes the name of the resource and the permitted use amount of the resource, and is configured so that the billing amount can be easily calculated. FIG. 6 is an explanatory diagram showing a specific configuration of the accounting log record.
As shown in the figure, the resource log record is a record including a print request user name, a resource name, and a use (permission) amount.

The accounting information is recorded in the accounting server 100
The processing is performed in the accounting log processing unit 210 in FIG. The reply of the print permission file 110 to the business client X1 is represented by (2) in FIG.

The business client X1 transfers the print file 204 to be printed to the print server Y1, but prior to the file transfer, the accounting server 1
The print permission file 110 returned from 00 is transmitted to the print server Y1 in advance. The transmission of the print permission file 110 is indicated by (4) in FIG.

Next, the business client X1 transmits the print data file 204 to the print server Y1, following the transmission of the print permission file 110. The transmission of the print data file 204 is indicated by (5) in FIG.

When printing the print data file 204, the print server Y1 refers to the print permission file 110 received immediately before. Then, it is checked whether the print data file 204 is uniquely recognized by the print data recognition key in the print permission file 110. This inspection is performed by the print monitoring unit 212.

When the print monitoring unit 212 in the print server Y1 determines that the print data file 204 cannot be uniquely recognized from the print data recognition key, it notifies the user (business client X1) that printing is impossible.
This notification is indicated by (7) in FIG.

Further, when printing is not performed,
It is often convenient for management to provide the same notification to the network administrator as well as the client. Therefore, it is desirable that the print monitoring unit 212 notifies not only the client but also the network administrator of the audit information indicating that the printing has not been performed.

It is preferable that the recognition be performed using a key, but it is also a simple method to simply look at the file name. By simply comparing only the file name, it is checked whether or not the file name described in the print permission file 110 and the file name of the print data file 204 match.

On the other hand, when the print data file 204 transmitted by the print data recognition key can be uniquely recognized, the printing process is started. This printing process is described in FIG.
Is shown by (8). This printing process is performed in the print processing unit 214 in the print server Y1.

At this time, during the execution of the printing process, the consumption of the used resources such as the number of pages to be printed is monitored, and the print permission file 1 is monitored.
Monitoring is performed so as not to exceed the range specified in 10. This monitoring is specifically performed by the print monitoring unit 212.

When the print data exceeds the range specified by the print permission file 110, the print processing is interrupted, and the user is notified of the interruption.

FIG. 4 shows an example of the allowable amount of each resource specified in the print permission file 110. Thus, the monitored resource includes, for example, the number of prints (sheets).
And print processing time (minutes), print data amount (byte), print toner amount (gram), and the like (see FIG. 4). The creation of these print permission amounts is performed by the print permission file generation processing unit 2
06.

In the present embodiment, the printing process is stopped when even one kind of resource exceeds the permitted amount among the permitted amounts of these resources specified in the print permitted file 110.

The process of interrupting the printing process is described in FIG.
In (6). Also, when the printing process is interrupted, it is preferable to notify the user of the interruption as described above. This notification is indicated by (7) in FIG.

In the embodiments described above, the permitted amounts of the respective resources are individually set. However, in the actual printing process, it is considered that the same permitted amount is often used repeatedly. Therefore, it is also preferable that a predetermined combination of the permitted amounts of each resource is defined in advance as a class, and the business client designates the permitted amounts of a plurality of resources collectively by using this class.

That is, the business client X1 that requests printing does not specify the amount of each resource for which use permission is to be given, but specifies the class. It is preferred to specify the amount at one time.

FIG. 5 shows an example of the print permission class. As shown in this figure, for example, the print permission class A defines the number of prints as ten, but is a print permission class that does not limit the other print processing time or the like. In the print permission class B, the permitted number of prints is one.
The print permission class is 00 sheets, but there is no restriction on other print processing time and the like. The print permission class C is
The permitted number of prints is 100, the permitted amount of print processing time is 60 minutes, and the permitted amount of print data is 4096.
This is a print permission class of K bytes. The print permission class D includes the number of prints, print processing time, print data amount,
This is a printing permission class that has no restrictions on the printing.

Specifically, means for storing the table as shown in FIG. 5 is provided in the print permission file generation processing unit 206 of the accounting server 100. The table storage means stores a predetermined print permission class. Prior to the actual printing process, it is necessary to store the data of the print permission class in the table storage means.

Now, for the accounting server 100 provided with the table storage means for storing the print permission class, the business client X1 sends the print request file 2 describing the print permission class, which is a combination of the permitted amounts of the resources to be used.
02 is transmitted. Then, the print permission file generation processing unit 206 in the accounting server 100 searches the print permission class table storage unit for a print permission class described in the print request file 202. Then, the requested permission amount of each resource for printing that the found print permission class means is read from the table storage unit that stores the print permission class. After the requested permission amount of each resource is obtained, the print permission file generation processing unit 206 generates the print permission file 110 based on the permission amount.

As described above, the billing server 100, which is a characteristic configuration in the present embodiment, receives the print request file 110 from the business client X1.
Is generated, and billing information is created based on the requested resources used for printing, and recorded in the billing information log file 208.

In the monthly processing or the like, the billing information is compiled for each user or user group from the billing information log file 208 on the billing server 100, and a billing total file 216 and a billing summary form 218 are created. The accounting process and the creation process are performed by the accounting information aggregation processing unit 220 in the accounting server 100. The process of reading the billing information log by the billing information totaling unit 220 is indicated by (a) in FIG. The process of creating the accounting summary file 216 by the accounting information aggregation processing unit 220 is shown by (b) in FIG.

The accounting information totaling section 220 has an accounting table 500 storing the names of resources and the amount of accounting per unit amount of resources.

Based on the billing table 500 and the billing information log file 208, the billing information totalizing unit 220
Performs monthly tabulation processing and the like. FIG. 7 is an explanatory diagram showing the concept of the operation of the monthly totaling process. As shown in FIG. 7, the charging table 500 stores the charging amount per unit of each resource, and the charging information log file 208 records the amount of resources used by each user. . Based on these two pieces of information, the billing information tallying unit 220 performs monthly tallying processing. As a result, FIG.
As shown in (1), the billing amount is calculated and calculated for each user.

The business client X1 is 1 in FIG.
Although only one is shown, this business client X1 can be freely added. When the business client X1 is added, if only the connection from the business client X1 to the charging server 100 is set, the printing request from the new business client X1 is automatically charged. As a result, the plurality of print servers Y1 connected to the local area network 200
It is not necessary to register a new business client X1 for each of the above, and it is possible to easily add the business client X1.

Further, according to the present embodiment, not only the business client X1 but also the print server Y1 can be easily added. When the print server Y1 is newly added to the local area network 200, the new print server Y1 is automatically set simply by setting the accounting server 100 so that the business client X1 can newly access the print server Y1. Can be charged for the print processing performed by the user.

User to be charged (or user group)
May be added to the billing server 100 as desired. This setting of the user group and the like is used only when the accounting information is totaled, and the information only needs to be known by the charging information aggregation processing unit 220. As a result, the business client X1 and the print server Y1 do not need to be changed at all.

In the present embodiment, the accounting server 100 is a single independent server device, but it is also preferable that the accounting server 100 is constituted by a business server on which a business program runs.

Embodiment 3 This embodiment is an embodiment using a print spooler, and its explanatory diagram is shown in FIG.

As shown in FIG. 8, a feature of this embodiment is that the print server Y1 is provided with a print spooler 221, and as an actual printer, it is directly connected to the print server Y1. Connected printer 222 and local area network 20
0 is directly under the control of the print server Y1. And
The print spooler 221 stores the print permission file 110
Or, the print data file 204 is spooled. The network printer 224 has an interface for connecting to the local area network 200, and this interface corresponds to connection means of the present invention.

Hereinafter, the operation of this embodiment will be described.

First, the business client X1 notifies the accounting server 100 of the print request file 202 and the print data file 204, and sends the print permission file 11
Get 0. The transmission of the print request file 202 and the print data file 204 is indicated by (1) in FIG. 8, and the operation is the same as in the second embodiment described with reference to FIG. In addition, the accounting server 100 determines that the print permission file 110
8 is indicated by (2) in FIG. 8, which is the same operation as that of the second embodiment in FIG. The charging server 100 has the same configuration as the charging server 100 of the second embodiment.

The business client X1 sends the print permission file 110 and the print data file 204 to the print server Y1. The print server Y1 supplies the transmitted print permission file 110 and print data file 204 to the print spooler 221.

The print spooler 221 transmits the transmitted print permission file 110 and print data file 204
Are stored in the spool area 226, and the execution of the printing is scheduled. At this time, the print data file 20
If the print permission file 110 has not been transmitted prior to Step 4, the print spooler 221 rejects spooling.

The spool area 226 specifically stores F
A memory area and a disk area which are buffers of the IFO and are under the control of the print spooler 221 are used.
The print spooler 221 schedules print processing for a set of the print permission file 110 and the print data file 204 stored in the spool area 226. This scheduling process itself is a well-known technique.

The print processing unit 22 of the print spooler 221
Reference numeral 8 denotes a print permission file 110 whose print order has been turned.
And checks whether the contents of the print data file 204 are appropriate. That is, the print processing unit 228
The print monitoring unit 212 according to the second embodiment in FIG.
This is a means that also has the function of: Specifically, the print data recognition key in the print permission file 110 is read, and the print data file 204 sent in pairs (sent as a set) is uniquely identified using the print data recognition key. A check is made to see if it can be recognized. As a result of this inspection, if it can be uniquely recognized, it is determined that printing can be performed, and the print processing unit 228 determines the number of available resources such as the number of print papers specified in the print permission file 110. Execute print processing within the limits.

As described above, the print processing unit 228 inspects the print data file in the print spooler 221.

More specifically, the print processing unit 228 sends the print data of the print data file 204 to the directly connected printer 222 directly connected to the print server Y1 or the network printer 224 connected to the local area network.

According to the present embodiment, since the print processing unit 228 is provided in the print spooler, the spool area 22
6, the print data file 204 and the print permission file 11
While 0 is stored, it is possible to check whether the contents of the print data file 204 are valid. As a result, a smooth billing method can be realized by using the conventional network printer 224 connected to the local area network as it is, without providing the printer itself with the means for executing the inspection.

It is also preferable to use a print server adapter device having the functions described in the present embodiment.
When the print server adapter is used, a print data supply unit that supplies the print data file to the printer is provided in the print server adapter only when printing of the print data file 204 is permitted. Will be.

Embodiment 4 In the above embodiment, the inspection such as the number of print sheets recorded in the print permission file 110 is performed by the print monitoring unit 212 or the print processing unit 22.
8 was performed by the monitoring unit.

However, when the program itself running on the business client X1 sends the print data file 204 to the print server Y1, it refers to the contents of the print permission file 110 to determine whether the print permission is correctly given. It is also preferable that the inspection itself is performed, and that the program itself monitors the printing operation.

In this embodiment, the print request input program 23 in the business client X1 is
Let's give an example where 0 monitors printing.

An explanatory diagram of the fourth embodiment is shown in FIG. As shown in FIG. 9, this system connects a business client X to a local area network 200.

Among them, the billing server 100 and the print server Y1 have the same configuration as the billing server 100 and the print server Y1 in the above-described embodiment. A characteristic configuration of the present embodiment is that the business client X1 includes a print monitoring unit 232 in the print request input program 230.

The business client X1 obtains the print permission file 110 from the accounting server 100 in the same manner as in the above-described embodiment. Then, printing is performed by transmitting the print permission file 110 and the print data file 204 to the print server Y1. These operations are the same as in the above embodiment.

A characteristic feature of the present embodiment is that the print request input program 230 for requesting printing has a print monitoring unit 232. by this,
Print permission file 110 sent to print server Y1
The print monitoring unit 232 performs an inspection on the contents of the print data file 204 and the print data. This monitoring operation is indicated by (1) in FIG. As a result of this monitoring, if the contents of the print data file 204 exceed, for example, the number of print sheets in the print permission file 110, the fact is reported to the print request input program 230, and the print request input program 230 To stop. Specifically, a new print data file 2
04 is not transmitted, and the print server Y1 is requested to stop printing.

As described above, since the print monitoring is performed on the side of the business client X1, more advanced print management can be performed while using a conventional printer or a conventional print server.

Embodiment 5 In each of the above-described embodiments, the print permission file 110 generated by the accounting server 100 has been transmitted to the business client X1. However, the print permission file 110 generated by the accounting server 100 for each request in response to a print request from the business client X1 is likely to be a file having substantially the same contents. The reason is that the print format is often a fixed format and the number of prints is often determined according to the size (number of pages) of the print data file 204.

Therefore, it is not only wasteful to generate the print permission file 110 having almost the same contents every time a print request is generated and to transmit the print permission file 110 to the business client X1, but also increase the traffic on the local area network 200. There is a risk that it will be done. Therefore, the print permission file 110 is generated in the print permission file generation processing unit 206 of the accounting server 100, but the print permission file 110 is
It is also conceivable to send only the file name. In the fifth embodiment, charging server 100 having such an operation is described.
FIG. 10 is an explanatory diagram thereof.

As shown in FIG. 10, the business client X1 first notifies the print request file 202 and the print data file 204 to the accounting server 100, and requests printing permission.

This operation is shown by (1) in FIG. 10 and is the same as in the above-described embodiment.

The accounting server 100 stores the print permission file 1
10 are generated in the same manner as in the above-described embodiment. Then, while the print permission file 110 itself is held inside the accounting server 100, only the file name of the print permission file 110 is transmitted to the business client X1.

Now, this operation of transmitting only the file name of the print permission file 110 is described in (2) in FIG.
Indicated by

As described above, since only the file name of the print permission file 110 is transmitted to the business client X1 instead of the print permission file 110 itself, the traffic volume on the local area network 200 is reduced.

Next, the business client X1 transmits the file name of the print permission file 110 and the print file 204 to the print server Y1. As a result, the business client X1 requests the print server Y1 to print the print data file 204.

The print server Y1 reads the print permission file 110 held by the charge server 100 from the charge server 100 based on the file name of the print permission file 110 sent from the business client X1. This reading operation is performed by the print monitoring unit 212.

The print monitoring unit 212 prints the print permission file 11
0, it is checked whether or not the printing is permitted. If the printing is permitted, the print processing unit 214 of the print server Y1 sends the print data file 204 transmitted by the business client X1. Start printing. Further, during the printing process, the amount of resources used for printing is monitored. These inspections and monitoring are the same as in the above-described embodiment.

More specifically, when printing is to be performed exceeding the number of printing papers specified in the print permission file 110 during printing, the print monitoring unit 2
12 requests the print processing unit 214 to stop, and the print processing unit 214 stops printing. Such a series of operations are shown in FIG. 10 as (3), (4), (5),
Each is indicated by (6).

When the printing of the print data file 204 is completed, the print monitoring unit 212 of the print server Y 1 sends the print permission file 11 stored in the accounting server 100.
0 is deleted.

The reason why the print permission file 110 is deleted is to prevent the same print permission file 110 from being used more than once. That is, unless the created print permission file 110 is deleted, the business client X1 can issue the same print request to the print server Y1 any number of times by using the print permission file name twice or more. . On the other hand, the accounting process in the accounting server 100 is performed only once. For this reason, in the present embodiment, the print monitoring unit 212 deletes the print permission file 110 every time one print is completed.

It is preferable that the function of the print server Y1 in the present embodiment is provided in the print server adapter device. In this case, in addition to the above-described functions, the print server adapter device transmits the print data file 204 to the printer device when printing of the print data file 204 is permitted.
A print data file supply unit for supplying the print data file 204 needs to be provided.

Embodiment 6 FIG. In each of the embodiments described above, the charging server that charges the print request for the number of sheets required for the printing has been described. However, it is also preferable that the charging server described above is applied to charging other than charging for print processing. For example, in the case of charging the file transfer processing according to the size of the transfer file, the charging server described above can be applied as it is.

In the sixth embodiment, the second embodiment is directly replaced with a charge for the file transfer process, and FIG. 11 is an explanatory diagram thereof. FIG.
As shown in FIG. 1, this system includes a business client X1 connected to a local area network 200, a billing server 300, and a file transfer server Z1.
It is composed of In the sixth embodiment, the billing target is not the number of printing paper sheets, but the number of bytes of a transfer file, the time required for transfer, and the like. The basic operation principle of the billing server 300 is exactly the same. .

First, the business client X1 transmits the transfer request file 302 and the transfer data file 304 to be transferred to the charging server 300. This transmission operation is indicated by (1) in FIG.

The transfer permission file generation processing unit 306 in the accounting server 300 generates a transfer permission file 410 based on the two transmitted files. The generated transfer permission file 410 is returned to the business client X1. This reply process is indicated by (2) in FIG.

In the charging server 300, a transfer permission file 410 is generated, and charging information for the transfer processing is stored in a charging information log file 308 in a charging log processing unit 310. This storing operation is indicated by (3) in FIG.

Next, the business client X1 transmits the transfer permission file 410 and the transfer data file 304 to be transferred to the file transfer server Z1. The transfer of the transfer permission file 410 is indicated by (4) in FIG. 11, and the transmission of the transfer file 304 is indicated by (5) in FIG.

The operation of the file transfer server Z1 is the same as that of the above-described print server Y1, except that the transferred file is transferred instead of being printed instead of being printed. Transfer processing unit 3
14 transfers the transfer data file 304 to the transfer destination server Z2. Prior to this, the transfer monitoring unit 312 checks whether the file permitted by the transfer permission file 410 matches the transfer data file 304 or not. If they do not match, the transfer is stopped. If the transfer time or the number of transfer bytes permitted by the transfer permission file 410 exceeds during the transfer operation, the transfer monitoring unit 3
In step 12, the transfer is stopped in the same manner as in the second embodiment. In either case where the transfer processing is not performed or the transfer is stopped, the transfer monitoring unit transmits a message to that effect to the business client X1. The process of transmitting this message is indicated by (7) in FIG.

In the sixth embodiment as well, various clients such as a business program requesting file transfer and a predetermined batch process can be used as clients, and the operation in this case is the same as the operation described above. It is exactly the same.

As described above, this embodiment is an example in which the second embodiment is applied to a file transfer process instead of a print operation. In other words, the charging server 300 according to the present invention can be widely applied to various services to be charged. In the above-described second embodiment, the preferable charging server is described in the case where the printing process is charged based on, for example, the number of sheets. In the sixth embodiment, the operation of the accounting server in the case where accounting is performed based on the number of transfer bytes in the file transfer has been described. As described above, the billing server according to the present invention is used for providing services to be widely billed.
