  Other objects, configurations and effects of the present invention will become apparent from the following description.

  FIG. 1 is a schematic configuration diagram of a trail management system according to the first embodiment of the present invention.

  The certificate server 10 is disposed at the head office of an insurance company, for example, and is coupled to the Internet 12 via a router 11A. On the other hand, a branch office of this company has a LAN configured by connecting clients 131 to 13n as n trail management apparatuses, m network printers 141 to 14m, and a log server 15 through a communication medium. It is coupled to the Internet 12 via a router 11B. In FIG. 1, only one branch office is shown for simplicity.

  FIG. 2 is a functional block diagram showing the clients 131 to 13n and the network printers 141 to 14m as representatives of one client 131 and one network printer 141 in the trail management system of FIG.

  In the certificate server 10, a form collection 101 and a certificate database 102 are stored in a hard disk drive (HDD) 100. The form collection 101 stores form data of various certificates. On the other hand, the certificate database 102 stores data of each insurance subscriber and management data related thereto. A part of this management data is used as print job log data, which will be described later, and includes a handler code in charge of insurance, a certificate type, a certificate serial number, and a trail management necessity code.

  This certificate serial number need not be unique for all certificates. Also, the trail management necessity code is for collecting only the logs of certificates that need to be managed.

  The certificate file creation unit 103 searches the certificate database 102 via the DBMS (database management system) 104 based on the certificate selection condition requested by the client, and forms collection 101 according to the type of certificate requested by the client. The form is called, and the certificate file is created by entering the search result data, the certificate file creation date and time, and the certificate ID. The search result data includes certificate print target data and non-print target data, and the non-print target data includes the print job log data. The certificate file creation date / time and certificate ID are also part of the print job log data.

  For example, the certificate ID is expressed as “PC012000700709000023XRT1”, the first four characters “PC01” are the terminal code of the client 131, and the next 16 characters “2002070709010823” are the date when the certificate file was created (July 07, 2002) and This is the time (09:01:08 second 23 milliseconds), and the next four characters “XRT1” are the identification code of the certificate form. The terminal code of the client 131 is acquired from the verification data 105 at the time of terminal authentication.

  On the other hand, in the collation data 105, the IDs and passwords of the terminals permitted to access and the users permitted to access among the clients (terminals) 131 to 13 m are registered. The Web server 106 supplies a request from the client to the authentication unit 107, and in response to this, the authentication unit 107 refers to the collation data 105 if it is an authentication request, and whether the client and the user are registered. Determine whether. If the web server 106 makes an affirmative determination, it temporarily registers the IP address of the packet, and then passes a certificate file creation request supplied from the user to the certificate file creation unit 103. The certificate file creation unit 103 creates a certificate file as described above and transmits it to the user via the Web server 106.

  In the client 131, the user operates the input device of the console 1311 to start a Web browser, and requests an authentication page from the certificate server 10. When the page is displayed on the Web browser, the user operates the console 1311 to input the user ID and password, and presses the send button. As a result, the user ID, password, and data of the terminal code 1312 are transmitted to the certificate server 10. If the authentication unit 107 performs authentication as described above and determines that the user is a legitimate user and terminal, the authentication unit 107 returns a search page for the certificate database 102 to the control unit 1310 via the Web server 106. The user inputs selection conditions on the screen of this page and presses the send button.

  As a result, the conditions are supplied to the certificate file creation unit 103 via the Web server 106 and the authentication unit 107. As described above, the certificate file creation unit 103 extracts certificate data that satisfies the conditions and fills the form to create a certificate file, and supplies this file to the control unit 1310 via the Web server 106. This certificate file is described in, for example, an XML format, and in order to print it, it is necessary to convert it into data that can be interpreted by the printer driver 1317.

  Here, the network printer 141 is provided with an SNMP agent 1411a for monitoring states such as out of paper, out of toner, and power off. On the other hand, the client 131 is provided with an SNMP manager 1313.

  When receiving the certificate file, the control unit 1310 supplies the certificate file to the print file creation unit 1315 and the print job log extraction unit 1316. In response to this, the print file creation unit 1315 issues a check request to the printer status check unit 1314. In response to this, the printer status check unit 1314 inquires of the SNMP agent 1411a about the printer status via the SNMP manager 1313. In response to this, the SNMP agent 1411a supplies the above status to the printer status check unit 1314 via the SNMP manager 1313. The printer status check unit 1314 reports this status to the print file creation unit 1315.

  Upon receiving a printer normality report, the print file creation unit 1315 converts the contents of the certificate file into a data file that can be interpreted by the printer driver 1317 and supplies the data file to the printer driver 1317. The printer driver 1317 converts this data file into a print data file described in PDL (page description language), and supplies it to the network printer 141 via the spooler 1318. This print data file includes data indicating the certificate ID and the paper type. The print data file further includes the number data of one certificate, which is supplied to the print log extraction unit 1316 as one of the print job log data. The paper type is determined by the form type, and the form type is included in the certificate ID, so the paper type is determined based on this.

  The print job log extraction unit 1316 extracts the above-mentioned print job log data from the certificate file, adds the certificate ID and the number of sheets as a part of the print job log data, and sends these print job log data via the DBMS 1319. The print job log table 1321 in the HDD 1320 is stored. FIG. 3A is an explanatory diagram of the print job log table 1321.

  FIG. 4 is a schematic block diagram of a printer related to the present embodiment. FIG. 5 is an explanatory diagram of a memory management list stored in the memory of FIG. FIG. 6 is a schematic time chart showing processing in the printer of FIG.

  In the network printer 141, a print engine 1430 is connected to the controller board 1410 via the print engine board 1420.

  In the controller board 1410, the control unit 1411 includes a processor and a program ROM coupled thereto. The program ROM stores an OS, a control program, and the SNMP agent 1411a program shown in FIG. The control unit 1411 performs the following control according to this control program.

  The control unit 1411 adds a management block to the memory management list as shown in FIG. 5 and allocates memory to the OS before storing the following print data and bitmap data for one page in the memory 1414. Request. In the management block, after the value to be entered is determined, the value is entered. This management block includes a pointer (NADR1) indicating the head address of the next management block, a certificate ID (PC01200070709000023XRT1), the page number (Page1), and the identification of the paper feed stage on which the paper to be used is placed. It consists of a code (Tray 1), the type of paper to be used (Plane), the storage start address (SADR1) of the data of this page, and the storage end address (EADR1) of the data of this page. When the pointer value is 0, it indicates that the management block is the last block in the list. This memory management is the same for the print engine board 1420.

  The control unit 1411 stores the print data supplied from the network interface (NIC) 1412 in the DRAM of the memory 1414, and transmits job start status data together with the certificate ID to the client 131 (FIG. 6A). FIG. 6 shows a case where each of the prints JOB1 to JOB4 prints one receipt.

  In parallel with the print data storage in the memory 1414, the control unit 1411 causes the RIP 1413 to develop the image data included in the print data into a bitmap and temporarily store the result in the memory 1414 (FIG. 6B). ).

  Here, the network printer 141 includes a plurality of paper feed stages 1440 to 1442, the user can set the paper type and paper size for each paper feed stage, and the data is stored in the NVRAM of the memory 1414. . This data includes data indicating which paper type is used when the designated paper type does not exist in the network printer 141. When the paper feed stage selection is in the automatic mode, the control unit 1411 determines the paper feed stage based on the paper type and paper size included in the print data.

  When the bitmap development for one page is completed, the control unit 1411 refers to the list of FIG. 5 and uses the NIC 1412 as a part of the discharge log data together with the paper ID (tray) number and paper type along with the certificate ID. To the client 131.

  The control unit 1411 includes a direct memory access controller (DMAC), thereby supplying the bitmap data temporarily stored in the memory 1414 to the print engine board 1420 together with the data of the control block, and the memory management block thereof. Are deleted, and the OS is requested to release the corresponding area.

  The print engine board 1420 includes a control unit 1421 and a memory 1422. The control unit 1421 includes a processor and a program ROM coupled to the processor. The ROM stores an OS and a control program. The processor stores the control program. The following control is performed according to

  The control unit 1421 adds the memory management block received from the control unit 1411 to the memory management list as shown in FIG. 5 when the bitmap data is stored in the memory 1422 for one page. Request memory allocation.

  The control unit 1421 reads the DMA-transferred bitmap data from the memory 1422 by FIFO, generates a video signal by adding a synchronization signal thereto, and supplies the video signal to the print engine 1430. In the print engine 1430, the photosensitive drum is exposed by this video signal to form an electrostatic latent image, which is developed with charged toner.

  On the other hand, the front stage 1443 of the paper transport mechanism is controlled by the control unit 1411 so that the paper is taken out from the paper feed stage selected as described above, transported and fed to the transfer section of the print engine 1430, and the toner. The image is transferred to the paper. This sheet passes through the transfer unit of the print engine 1430 and is further conveyed by the rear stage 1414 of the sheet conveying mechanism. The image formation in FIG. 6D shows these exposure, development, and transfer.

  The sheet is further conveyed by the rear stage 1414 of the sheet conveying mechanism and discharged onto a tray (not shown). At this time, the sheet discharge sensor 1445 detects the trailing edge of the sheet (FIG. 6E).

  When the control unit 1421 supplies data for one page to the print engine 1430 and the sheet trailing edge detection signal (discharge completion signal) from the sheet discharge sensor 1440 becomes active, the certificate ID and page number data of this page. Is sent from the memory management list to the control unit 1411, and the OS is requested to release the corresponding memory area, and the memory management block is deleted. In response to the transmission, the control unit 1411 transmits the certificate ID and the page number as part of the discharge log data to the client 131 via the NIC 1412 (FIG. 6F). Since one job is printing one page in FIG. 6, the job end status is also transmitted at the time of transmission. In FIG. 2, since the print file creation unit 1315 knows the number of prints, the print log job extraction unit 107 determines that the job has ended when the page number received from the printer 141 matches this number. May be. In this case, transmission of the job end status is not necessary.

  FIG. 7 shows the discharge log data supplied from the network printer 141 to the discharge log collection unit 1323 and the discharge added by the discharge log collection unit 1323 when two receipts are normally output from the network printer 141. Indicates log data. In this figure, “20020707090010” on the left end indicates that the network printer 141 received a job start status from the controller board 1410 at 9:00:10 on July 7, 2002. “PC012000700709000023XRT1” is a certificate ID. “Input = Tray 1” supplied during job execution indicates that the paper in the first paper feed tray is used, and “Media = Plane” indicates that the paper type is plain paper. The third date and time “2002077090015” from the top is the date and time received by the discharge log collection unit 1323 from the control unit 1421 via the control unit 1411 in response to the completion of the discharge.

  FIG. 8 shows a discharge log when the network printer 141 is turned off and then turned on while print data is being transmitted from the client 131 to the network printer 141. In this case, there is JOB END START instead of the JOB END NAME line for the first print page, indicating that retransmission from the client 131 to the network printer 141 has occurred.

  FIG. 9 shows a discharge log when the network printer 141 is turned off after the print data is completely transmitted from the client 131 to the network printer 141 and before the final page is discharged from the network printer 141. In this case, the print data is lost without being discharged to the last page. Since the print data has been transmitted from the printer driver 1317 to the network printer 141 via the spooler 1318, retransmission from the spooler 1318 does not occur.

  Returning to FIG. 2, the discharge log collection unit 1323 stores the received discharge log data in the discharge log table 1322 of the HDD 1320 via the DBMS 1319. FIG. 3B is an explanatory diagram of a discharge log table (discharge completion log table) 1322. The discharge log includes a transmission source IP address (static IP address of the printer) included in the received packet, a time when the discharge log collection unit 1323 receives discharge completion from the network printer 141, a certificate ID, a discharge page number, and a paper feed tray number. And paper type.

  The print job log table 1321 and the discharge log table 1322 constitute a relational database with the certificate ID as a common column. When the user operates the console 1311 to give a selection condition to the search unit 1324 and supply a search command, the search unit 1324 receives corresponding data from the print job log table 1321 and the discharge log table 1322 via the DBMS 1319 based on this. Is read. This data is displayed on the display device of the console 1311 via the DBMS 1319 and the search unit 1324.

  On the other hand, the log collection client 1325 collects print job log data from the print job log extraction unit 1316, collects discharge log data from the discharge log collection unit 1323, and transmits these to the log server 15. The log collection client 1325 may wait for a predetermined number of records of log data to accumulate and transmit them to the log server 15.

  In the log server 15, these data are supplied to the log collection unit 151 via the Web server 150, and the log collection unit 151 sends these data to the print job log table 154 and the discharge log table 155 of the HDD 153 via the DBMS 152. To add. When the user operates the console 156 to give a selection condition to the search unit 157 and supply a search command, the search unit 157 responds to this from the print job log table 154 and the discharge log table 155 via the DBMS 152. Read data. This data is displayed on the display device of the console 156 via the DBMS 152 and the search unit 157.

  FIG. 10A shows search conditions displayed on the screen of the console 156. In this example, the handler code and the printing date are selection conditions. When the execution button on the screen is pressed, a search result as shown in FIG. 10B is displayed, for example. A circle in the discharge column in the figure indicates that the printed certificate has been discharged, and a cross indicates that the printed certificate has not been discharged.

  When the number of days set by the console 156 elapses, the log management unit 158 deletes past data exceeding the number of days stored in the print job log table 154 and the discharge log table 155 via the DBMS 152.

  Similarly, when the number of days set by the console 1311 elapses, the log management unit 1326 deletes past data exceeding the number of days stored in the HDD 1320 and the print job log table 1321 via the DBMS 1319.

  According to the first embodiment, in response to a request from the client 131 in the certificate server 10, certificate data that satisfies the condition is extracted from the certificate database 102, and the extracted data (the handler code used as print job log data) is extracted. Certificate type, certificate serial number and certificate necessity management code) and data related to the print job (certificate file creation date and time and certificate ID used as print job log data) are created and transmitted to the client 131. Since the print job log data is extracted by the client 131, the print job log data can be efficiently collected.

  Also, certificate print data is created based on the certificate file (the number of prints of one certificate known at this stage is also used as one of the print job log data) and transmitted to the printer 141. The printer 141 is connected to the controller board 1410. After receiving the print data, the certificate ID is sent to the client 131 as a part of the discharge log data together with the job start status. After the creation of bitmap data for each page, the paper tray number and paper type are discharged together with the certificate ID. After sending the image to the client 131 as part of the log data and forming an image on the paper, it further confirms the completion of paper discharge for each page and sends the discharge page number together with the certificate ID to the client 131 as part of the discharge log data. Since the data is transmitted, the trail in the printer 141 is stepwise, that is, Can to know in detail, thereby an effect that it becomes possible to perform detailed trail management.

  Furthermore, since the client 131 adds the source IP address (static IP address of the printer) and the packet reception date / time of completion of discharge included in the received packet to the discharge log data, more detailed print job log data can be efficiently used. There is an effect that it can be collected.

  Further, the print job log data and the discharge log data are transmitted to the log server 15, and both log data correlated with each other by the certificate ID are stored in the HDD 153 of the log server 15. Therefore, more detailed trail management is efficiently performed. There is an effect that it can be performed.

  In addition, since the print job log data includes the certificate handler code, the relationship between the certificate handler and the trail can be known only by the log, thereby producing an effect that the trail management can be performed more efficiently. .

  In addition, since the print job log data includes the number of pages of one certificate, there is an effect that trail management can be performed in more detail in relation to all pages of one certificate.

  Further, since the print job log data includes the certificate file creation date and time, the trail can be grasped in relation to this date and time, and the trail management can be performed in more detail.

  Furthermore, since the discharge log data includes the discharge log reception date and time as data relating to the discharge of the paper printed by the printer 141, the relationship between the time when the certificate file is created and the time when the print is discharged can be grasped. There is an effect that can be performed in more detail.

  Further, since the discharge log data includes the data of the paper type used for printing by the printer 141, it is possible to grasp the trail in relation to the paper type, thereby producing an effect that the trail management can be performed in more detail. .

  In addition, since the discharge log data includes the paper feed tray number used in the printer 141, the trail can be grasped in relation to the paper feed stage, and thereby the trail management can be performed in more detail.

  Further, since the print job log data and the discharge log data are also stored in the HDD 1320 in the client 131, the trail management can be performed only by the client 131.

  Note that the present invention includes various other modifications.

  For example, as shown in FIG. 10, when the discharge detection signal of the discharge sensor 1445 is supplied to the control unit 1411 and the video signal transmission for one page is completed from the control unit 1421 to the print engine 1430, the control is performed from the control unit 1421. The certificate ID and the page number are transmitted to the unit 1411, and the control unit 1411 outputs the certificate ID and the page number via the NIC 1412 in response to the subsequent activation of the paper discharge detection signal, that is, the previous stage In addition, the certificate ID and the page number at the completion of the discharge may be output to the outside by the control unit at the subsequent stage.

  In the above embodiment, the case where the certificate is a receipt has been described. However, the certificate may be another certificate that proves facts or rights, such as an application, an invoice, an invoice or a slip. . The printer may be a local printer connected to the client without going through a network.

  Further, the form collection 101 may be provided in the client 103 instead of being provided in the trail server 10. The data related to the creation of the certificate file included in the print job log data may be the date and time when the client 103 received the certificate file from the trail server 10. The data related to the discharge of the paper printed by the printer 104 may be the date and time detected by the printer. The paper type or paper feed stage data can be determined according to the form of the certificate, and the data may be stored in the certificate database 102 in which the form type is stored.

  Further, if the certificate serial number is unique, the certificate ID may be expressed by combining this with the certificate file creation date / time or the print file creation date / time.

  Further, data items to be logged may be determined according to a certificate type or a trail management necessity code (a case where management is necessary is further classified according to importance).
