Description

  The present invention relates to a printing technique.

  In recent years, there have been frequent incidents of leakage of confidential information such as corporate customer information. Once the information leakage incident becomes public, the trust of the company that caused the information leakage is lost, as well as enormous expenditures for damages and responses. Therefore, an appropriate information leakage countermeasure is required from the information management side.

  In this background, with the progress of digitization, networking, and mobile of information, it became possible to access a large amount of information at a time, and the portability of information was dramatically improved. It is inevitable that these trends will accelerate in the future.

  Conventionally, as a technique widely used as an information leakage countermeasure, there is a method of limiting who can access confidential information by setting an access right to confidential information or a storage server for storing the confidential information.

  However, in recent years, information leakage incidents tend to have an overwhelmingly large number of intentional internal crimes by persons authorized to access confidential information, and it is no longer enough to prevent information leakage by setting access rights. It cannot be said that it is a measure against leakage.

  On the other hand, as information to be protected from information leakage, it is necessary to take into account not only a large amount of information typified by customer information of large corporations but also a small amount of information but qualitatively important information. Such information can be easily taken out as printed matter, and there is a demand for measures that are conscious of preventing information leakage in printing.

  Conventionally, a technique for preventing information leakage has been proposed for a network printing system.

  For example, print permission information is set in a document or print data to be printed, the print permission information is referred to when printing is performed (see Patent Document 1), and the user is required to use a device connected to the network. There is a method for performing authentication (see Patent Document 2).

  In addition, the print data is stored in a reprintable state by the print server, and information such as the job name, client name, and user name is acquired to add a time stamp, and a bitmap is generated from the print data. For example, there is a method of storing the print log (see Patent Document 3).

  In addition to the above, there is also a method of acquiring a print log on the printer side and storing it in a server (see Patent Document 4).

Similarly, the print server receives the print data from the client and at the same time receives information that can uniquely identify the user, and generates a print log based on the print data and the user information so that it can be searched, viewed, and reprinted. There is also a method (see Patent Document 5).
Japanese Laid-Open Patent Publication No. 2004-252784 JP 2003-288327 A JP 2002-149371 A JP 2003-330677 PR Japanese Laid-Open Patent Publication No. 2004-118243

  However, the above-described conventional example in which print user information is embedded (Patent Document 1) and the one that performs user authentication (Patent Document 2) require a special application, a network device such as a special printer, and the like. It must be used for the intended use. In other words, when operating in offices that handle highly confidential information such as personal information in daily work, the environment that can be applied is reduced by introducing special printing applications and network devices such as special printers. There is a problem.

  In contrast, the methods disclosed in Patent Documents 3 to 5 do not have such a restriction, and there is no major problem in operation in a general office. If the method is limited to printing via a print server, the print content information is not limited. Can be collected, stored and tracked.

However, in the methods disclosed in these Patent Documents 3 to 5, the print data is stored in the PDL format as the print content information or in the intermediate file format when the print data is spooled on the server. When saving all the print data that is printed from the data size will be quite large,
-The load on the network becomes large.-To store for a long period of time, a large-capacity disk is required for the print server that is the storage destination, which is costly.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique for creating a searchable print log without requiring a special device.

In order to achieve the object of the present invention, for example, an information processing apparatus of the present invention comprises the following arrangement.

That is, will receive the print log information indicating the print log through the network are communicably connected to the print server to be transmitted to the log management server print log information received said, it is printed by the printing apparatus An information processing apparatus that stores a printer driver and an add-in module that generate print data, and transmits the print log information from the printer driver and the add-in module .
Upon receiving an instruction to print text information from the application software, the printer driver and the add-in module are operated to create document information including a user name, a printing time, and a job name. First creation means for creating page information that is information;
When the first creation means creates the document information, the printer driver is operated to create print data for causing the printing apparatus to perform printing based on the text information from the text information. Creating means;
First transmission means for transmitting the document information and page information created by the first creation means to the print management server as the print log information;
Determining means for determining whether or not the page information has been normally transmitted to the print management server by the first transmitting means;
If it is not determined that the transmission is normally performed by the determination unit, the print data generated by the second generation unit is not transmitted, and if it is determined that the transmission is normally transmitted by the determination unit, And a second transmission unit configured to transmit the print data created by the second creation unit to the printing apparatus.

  With the configuration of the present invention, a searchable print log can be created without requiring a special device.

  Hereinafter, the present invention will be described in detail according to preferred embodiments with reference to the accompanying drawings.

[First Embodiment]
<System configuration>
FIG. 1 is a block diagram illustrating a schematic configuration of a printing system according to the present embodiment. As shown in the figure, the printing system according to the present embodiment includes an archive server 14, a management client PC 15, a client PC 13, a print server 12, and a printer 11, each connected to a network 10 such as a LAN or the Internet. ing. Therefore, each can communicate data with each other via this network. The network 10 may be wired or wireless.

  The client PC 13 creates data to be printed and a print log of this data, and outputs print data and print log based on the created data to the print server 12. The print log will be described later. In the present embodiment, the data to be printed is text data.

  The print server 12 functions as a print server and includes a driver agent described later. The operation of the driver agent will be described later. The driver agent may be configured with a predetermined resident program.

  The printer 11 performs printing based on print data received from the client PC 13 via the print server 12.

  The archive server 14 receives and manages the print log created by reconstructing the print log received by the print server 12 from the client PC 13.

  The management client PC 15 searches the print log managed by the archive server 14 and performs a search such as when a specific print was performed by whom.

  Here, the print server 12 will be described. In addition to the driver agent described above, the print server 12 is installed with a printer driver for the printer 11 and an add-in module for acquiring a print log before reconfiguration from the client PC 13, so-called point-and-print. Depending on the function, the equivalent printer driver and Add-in module are also installed in the client PC 13. Accordingly, the print data is sent from the client PC 13 to the printer 11 via the print server 12.

  The print log is sent in XML format from the client PC 13 to the driver agent of the print server 12 through a named pipe. Then, the driver agent performs a reconfiguration process to be described later to improve the searchability for the text portion (text to be printed) in the print log, and uses the reconfigured print log as an XML file as an archive server having a Web service function. 14 through SOAP (Simple Object Access Protocol). The named pipe is a named pipe that is a shared memory area that allows two-way data exchange between a plurality of processes. You can use it as if you were writing to or reading from a file. SOAP is a protocol for calling data and services in other computers based on XML and HTTP.

  The archive server 14 combines the print logs divided into a plurality of XML files per job so as to be easily handled.

  FIG. 2 is a block diagram showing a hardware configuration of a computer applicable to the archive server 14, the management client PC 15, the client PC 13, and the print server 12. In the present embodiment, each device is assumed to be a computer having the configuration shown in FIG. 2, but the present invention is not limited to this.

  Reference numeral 21 denotes a CPU that controls the entire computer using programs and data stored in the ROM 22 and the RAM 23, and executes processes described later performed by an apparatus to which the computer is applied.

  A ROM 22 stores setting data, a boot program, and the like of a device to which the computer is applied.

  A RAM 23 has an area for temporarily storing programs and data loaded from the hard disk (HD) 24 and a work area used when the CPU 21 executes each process.

  Reference numeral 24 denotes a hard disk, in which an OS (Operating System) and programs, data, and the like for causing the CPU 21 to execute processes to be described later performed by a device to which the present computer is applied are stored. Is loaded into the RAM 23 in accordance with the control by the CPU 21 and is processed by the CPU 21. For example, when this computer is applied to the client PC 13, a driver of the printer 11 and an Add-in module program are stored in the hard disk 24, and when this computer is applied to the print server 12, this hard disk is stored. A driver 24 and an Add-in module program, as well as the driver agent program, are stored in 24.

  Reference numeral 25 denotes an input device, which includes a keyboard, a mouse, and the like. Various instructions can be input to the CPU 21 by an operator of the computer.

  Reference numeral 26 denotes a monitor, which is composed of a CRT, a liquid crystal screen, and the like, and displays the processing results by the CPU 21 with images and characters.

  An I / F (interface) 27 functions as an interface for connecting a device to which the present computer is applied to the network 10.

<System operation>
Next, the operation of the system according to this embodiment will be described. When printing a text file, the system according to the present embodiment creates and manages a log related to the printing. Hereinafter, processing performed by the system according to the present embodiment until the print log is created and managed will be described.

  First, processing performed by the client PC 13 will be described. Here, it is assumed that a text file to be printed is stored in the RAM 23 of the client PC 13. When the operator of the client PC 13 operates the input device 25 to input a print instruction for this text file, the client PC 13 executes the printer driver and Add-in module programs installed on the hard disk 24 to print the print target. A process of creating a print log including the print contents of the text file and outputting it to the driver agent of the print server 12 will be described in detail with reference to FIG. 3 showing a flowchart of the process.

  Note that programs and data for causing the CPU 21 of the client PC 13 to execute the processing according to the flowchart of FIG. 10 are stored in the hard disk 24 of the client PC 13 and are appropriately stored in the RAM 23 of the client PC 13 according to the control by the CPU 21 of the client PC 13. When the CPU 21 of the client PC 13 loads and performs processing using this, the client PC 13 executes each processing described below.

  First, the CPU 21 determines whether or not the operator has operated the application software using the input device 25 and has input a print instruction to the text file to be printed (step S301). At this time, the printer driver and Add-in module programs are loaded in advance from the hard disk 24 into the RAM 23 of the client PC 13, and these are in a print waiting state under the control of the CPU 21.

  If the CPU 21 detects that a print instruction has been input, the process proceeds to step S302, and information DocInfo1 is created in the XML format (step S302). The information “DocInfo1” includes the user name of the operator (in other words, the user name of the client PC 13), the print time, and the job name. The description regarding is omitted.

  Next, when the creation of the information called DocInfo1 is completed, the CPU 21 transmits the created information called DocInfo1 to the driver agent of the print server 12 via the I / F 27 (step S303). If this transmission is performed normally, the process proceeds to step S305 via step S304. If the transmission is not performed normally, error processing is performed. In the background of the processing in step S303, print data is generated in another thread based on the text file to be printed.

  When the information “DocInfo1” is normally transmitted, the operator of the client PC 13 sets the page header such as the paper size and resolution of the page to be printed before instructing to print the text file to be printed. Obtained from the setting data (step S305).

  Further, since the text to be printed is output from the application software, it is acquired (step S306), and the acquired text and information called PageInfo including the page header are created in the XML format (step S307).

  Here, the processing in step S306 and step S307 corresponds to one page by generating XML format information in units of DDI (device driver interface) commands acquired from the application via GDI, and repeating this processing. Generates PageInfo, which is information in XML format.

  For example, the application software outputs drawing commands and text to a printer driver or the like in the order in which the user created data. This is the same for the program of the Add-in module. For example, if the text is provided from the application software in a predetermined unit such as a character unit, a word unit, or a line feed unit, “identification indicating text” is used in this unit. The process of adding “tag information as information” is performed for all units constituting one page. Then, text information for this page is created by receiving end information of one page after all the units constituting one page are performed. That is, the created text information is obtained by individually managing each unit constituting the text to be printed. The process of creating text information is performed for all pages to be printed. In this way, PageInfo including text information for all pages and the page header is obtained.

  FIG. 4 is a diagram showing an example of text information in a certain page, in which “tag information as identification information indicating text”, that is, <text> and </ text> is added for each word and each character. Yes. If the word or character is the last one in the line, <text> and </ text> are added so as to include a line feed code (in the figure, “information” and “Confidential” are line feed codes “ Tag information is added as a set with “CR + LF”).

  In this way, text information to which tag information is added for each word or character is created, and PageInfo including this text information and the page header is obtained.

  Returning to FIG. 3, the PageInfo created in step S307 is transmitted to the driver agent of the print server 12 via the I / F 27 (step S308). If this transmission is performed normally, the process proceeds to step S310 via step S309. If the transmission is not performed normally, error processing is performed. At this time, if the transmission is successful, the print data of the page is transmitted to the print server 12 via the I / F 27. Since the print server 12 outputs the print data to the printer 11, the printer 11 performs printing on a recording medium such as paper based on the print data.

  Further, if information is secured as a print log, which will be described later, the information can be traced, so that output of print data can be permitted in a confirmed unit. It is also possible to output print data for all pages after acquiring print log information for all pages and confirming output. However, by performing print data output processing in units of pages, it is possible not only to speed up the first print, but also to reduce the total printing time and further to suppress the data temporary storage area in the client PC 13.

  Next, it is determined whether or not PageInfo has been transmitted to the print server 12 for all pages to be printed (step S310). If not transmitted, the process returns to step S305, and the process of step S305 and subsequent steps is performed for the next page. If PageInfo has been transmitted to the print server 12 for all pages, the process proceeds to step S311, and information such as the number of print pages, such as DocInfo2, including information obtained after the print processing is completed. It is created in the XML format (step S311), and is transmitted to the driver agent of the print server 12 via the I / F 27 (step S312). If this transmission is performed normally, the process returns to step S301 via step S313. If the transmission is not performed normally, error processing is performed.

  As described above, when printing one text file, the client PC 13 not only creates print data of this text file and transmits it to the print server 12, but also the DocInfo1, PageInfo, DocInfo2, etc. for this text file. Three types of XML format information are created, and the created three types of information are transmitted as print logs. In other words, the print log is made up of DocInfo1, PageInfo, and DocInfo2.

  Next, processing performed by the print server 12 will be described. As described above, when printing one text file, the print data and print log based on this text file are transmitted from the client PC 13 to the print server 12.

  The print server 12 outputs the received print data to the printer 11 as described above. However, the text information included in the PageInfo in the print log is reconstructed for reasons described later.

  FIG. 5 is a flowchart of text information reconstruction processing. Note that a program (driver agent) and data for causing the CPU 21 of the print server 12 to execute processing according to the flowchart of FIG. 10 are stored in the hard disk 24 of the print server 12 and are controlled by the CPU 21 of the print server 12. Accordingly, the CPU 21 of the print server 12 performs processing using this, and the print server 12 executes each process described below.

  First, the CPU 21 refers to the text information and deletes <Text> and </ Text> other than the first <Text> and the last </ Text> (step S51).

  Next, if a line feed code is included in the text information, it is replaced with a space (step S52).

  Next, if the control code (character code of 0x00 to 0xFF) is included in the text information, it is deleted (step S53), and the character code of each character in the text information is converted from Unicode to Shift-JIS. (Step S54).

  FIG. 6 is a diagram showing text information obtained when the text information shown in FIG. 4 is processed according to the flowchart shown in FIG. As described above, in the text information (pre-reconstruction text information) of FIG. 4, each character and word constituting the text to be printed is individually managed, but the text information (post-reconstruction) shown in FIG. In the text information), each character and word is concatenated and managed as a series of text. Thus, for example, even if the text information of FIG. 4 is searched with the word “personal information”, it does not hit, but if it is performed on the text information of FIG. Further, since each character in the text information shown in FIG. 6 is expressed by an SJIS code, this text information is not created depending on the installed OS, and is highly versatile. Through the above processing, the print server 12 can reconstruct the text information.

  By the way, a print log composed of the above three types of information in XML format (DocInfo1, PageInfo, DocInfo2) can be transmitted from the printer driver and Add-in through interprocess communication such as a named pipe. In an actual user environment, it is assumed that print log information is simultaneously sent from a plurality of client PCs to one driver agent. However, print log information for one job is sent in one session of a named pipe. For example, on the driver agent, a folder is divided for each job, and three types of print log information are managed together in the XML file format, and when one job is sent to the archive server 14, one job is stored in one SOAP session. It is possible to handle print log information for each job by sending print log information.

  Further, the archive server 14 combines the above three types of XML format information. As a result, the print log information of one job can be handled with one file. FIG. 7 is a flowchart of processing for managing the above-mentioned three types of XML format information.

  Note that programs and data for causing the CPU 21 of the archive server 14 to execute the processing according to the flowchart of FIG. 10 are stored in the hard disk 24 of the archive server 14 and are appropriately stored in accordance with the control of the CPU 21 of the archive server 14. 14, and the CPU 21 of the archive server 14 performs processing using this, whereby the archive server 14 executes each process described below.

  First, the XML file of DocInfo1 stored in the temporary job storage destination folder is acquired from the print server 12 (step S71). Further, an XML file of PageInfo is acquired (step S72), and an XML file of DocInfo2 is acquired (step S73).

  Then, the acquired three types of XML files are combined (step S74). Here, when there are a plurality of PageInfos, they are combined and further combined with DocInfo1 and DocInfo2.

  Then, the combined XML file is stored in the hard disk 24 owned by itself (step S75). As a result, print log information can be accumulated and managed in units of jobs.

  Further, as an implementation, for example, when the archive server is divided into a front-end Web service and a back-end storage / retrieval server, the web service is combined into one XML file and the storage / retrieval server uses the XML. There is a method in which information such as paper size and resolution in DocInfo1, DocInfo2, and PageInfo is stored in a DB and managed from a file, and text information is combined and managed in association with information in the DB on a job basis.

  Note that the process of registering the three types of XML files in the archive server 14 is not limited to this.

  Then, the operator of the management client PC 15 can search each post-reconstructed text information registered in the hard disk 24 of the archive server 14 for items including a predetermined keyword. This is because the character and word are combined by the reconstruction process and managed by the archive server 14 as a series of text, and the character code of each character in the text information is not dependent on the OS. This is due to something.

  If text information including a predetermined keyword is hit, the user who printed the text including the predetermined keyword can be specified by referring to DocInfo1 managed together with the text information, and the printing time can also be specified. it can.

[Second Embodiment]
In the first embodiment, the process performed by the print server 12 may be performed by the client PC 13. In that case, it is necessary to install the driver agent of the print server 12 in the client PC 13. Therefore, in this case, the print logs (DocInfo1, PageInfo, DocInfo2) generated by the client PC 13 are directly transmitted to the archive server 14.

  Further, the reconfiguration process may be performed on the archive server 14 side. In particular, when the print log storage destination on the archive server 14 side is another DB server, it is better to perform processing dependent on the DB server such as character code conversion on the archive server 14 side.

  Conversely, the XML combination of the above three types of print log information can be performed by a driver agent. This is considered better in order to reduce the load on the archive server 14 for file operations.

  According to each of the above-described embodiments, a special printing application or a network device such as a special printer is not required, and text information is handled as print contents. Therefore, the load on the network and the server can be reduced and the cost can be reduced. it can.

  Also, searchability can be improved by handling and reconfiguring the text information of the print contents.

  Furthermore, by handling the divided print logs in units of jobs, it is possible to collect information reliably in units of jobs when problems occur.
