Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printing control method, apparatus, and medium in a system including information processing such as a personal computer and a printer.
[0002]
[Prior art]
2. Description of the Related Art In recent years, job accounting systems that count the number of used sheets for each user who uses a printer connected to a network and charge based on the data have been commercialized.
[0003]
In the job accounting system, billing information such as the number of printed sheets is managed for each user. For this reason, when a user uses a printer belonging to a job accounting system, a mechanism in which the user can use the printer only after being authenticated by the system is normal. The user inputs authentication information such as an ID and a password to the system before executing the print job and receives authentication. Authentication is requested in units of print jobs.
[0004]
[Problems to be solved by the invention]
However, in such a system where authentication is performed in units of print jobs, even in a terminal occupied by a single user, authentication information is required to be confirmed each time a print job is issued by issuing a print request. It was very annoying and the operability was bad. On the other hand, when printing in an environment where multiple authentication information is used, such as a terminal shared by multiple users, accurate accounting information is obtained unless confirmation of authentication information for each print job is required. Can not do it.
[0005]
The present invention has been made in view of the above-described conventional example. The print control apparatus can flexibly change the authentication information confirmation procedure according to the operating environment and can allow the user to confirm the authentication information according to the operating environment. And a method and printing system.
[0006]
Further, when the authentication information is not confirmed for each print job, the authentication process is performed without confirming the authentication information every time printing is performed. In such a case, there is a problem that it is necessary to confirm that the authentication information is correct before printing.
[0007]
The present invention has been made in view of the above conventional example, and it is another object of the present invention to provide a printing control apparatus and method, and a printing system that can determine the correctness of authentication information in advance before printing.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention comprises the following arrangement.
[0009]
A print control method that performs user authentication processing during print processing and is input via the user interface of the printer driver. The Authentication information Information indicating whether or not to enable the job accounting function that counts the print amount of jobs The For holding means Holding step to hold and said holding means Held by When the information indicating whether or not to enable the job accounting function for counting the print amount of the job indicates that the job accounting function is enabled, the information is held by the holding unit Send authentication information to the authentication server, It is a program that counts the amount of printing An authentication request process for requesting authentication for the job accounting program and the holding means When the authentication information held by is sent to the authentication server and the authentication is successful When the information indicating whether to enable the job accounting function for counting the print amount of the job held by the holding unit indicates that the job accounting function is enabled, While sending print data to the printing device Counting Authentication information for the server Indicates the print amount printed using Send job accounting information On the other hand, if the information indicating whether or not to enable the job accounting function for counting the print amount of the job held by the holding means indicates that the job accounting function is not enabled, Without sending job accounting information indicating the print amount printed using the authentication information. If authentication is not successful, print data is sent to the printer. Against And an output step for controlling the output processing so as not to transmit.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
Hereinafter, a job accounting system suitable for applying the present invention will be described.
[0017]
<Outline of job accounting system components>
FIG. 1 is a diagram illustrating an example of a job accounting system. This system includes computers 101 and 102 serving as clients, a computer 1001 serving as a job accounting server, a conventional printer 103, and a printer 104 having a job accounting function. Various application programs are executed on the computers 101 and 102, and output by the application programs is printed by the printer 103 or the printer 104.
[0018]
Before explaining the entire system, the hardware or software components, such as a job accounting server application, a job accounting client application, and a printer with a job accounting function, will be described.
[0019]
(Printer with job accounting function)
The printer with job accounting function stores and manages the number of printed pages, paper size, duplex / single-sided printing, color / monochrome printing, etc. for each user in addition to the normal (conventional) printer function. A job accounting function and an authentication function for authenticating a user. User authentication is a function that checks whether authentication information sent from a job accounting client application (to be described later) is compared with user-specific information stored in advance, and whether or not to authenticate that the user is an authorized user. is there.
[0020]
(Conventional printer)
A conventional printer does not have a job accounting function, and performs printing based on received print data.
[0021]
(Job accounting server application)
The job accounting server application provides a function similar to the job accounting function of a printer with a job accounting function to a conventional printer that does not have a job accounting function. The job accounting server application is executed on a server computer that functions as a job accounting server, and the function corresponds to a printer with a job accounting function that is obtained by removing the printing function.
[0022]
This function can be roughly divided into two. The first is a user authentication function, and the second is a job accounting function. The user authentication function is the same as that of a printer with a job accounting function. However, since the job accounting server application does not have a printing function, it cannot be generated while printing the job accounting information. Therefore, the job accounting function stores and manages job accounting information transmitted from the job accounting client application.
[0023]
(Job accounting client application)
The job accounting client application roughly has two functions. The first is a user authentication function. When authentication is requested from the printer driver, the job accounting client application transmits the authentication information received together with the request to the job accounting server application or the printer with the job accounting function, receives the authentication result, and returns it to the printer driver.
[0024]
The second is a function for generating job accounting information. This function is performed only when the printer to be used is a conventional printer that is not a printer with a job accounting function. The job accounting client application acquires information related to printing as described later, and generates job accounting information such as the number of printed pages and the size from the information. Then, the generated job accounting information is transmitted to the job accounting server application. This second function functions only when a computer having a job accounting server application exists on the network.
[0025]
In the present embodiment, these authentication function and job accounting function are realized in a single module, but a function-specific module may be used.
[0026]
(Printer driver)
Printer drivers can be classified into two types in this embodiment.
[0027]
The first is a printer driver corresponding to the job accounting function. This printer driver has an authentication function for realizing a user authentication request UI on a computer screen prior to printing and issuing an authentication request to a job accounting client application. In addition, based on print data generated in response to a print request received from an application, the job accounting client application has a function of passing information that is the basis of job accounting information such as the number of print pages and the size to the job accounting client application. However, printers used include a printer with a job accounting function and a conventional printer without the function. When using a printer with a job accounting function, it is not necessary to pass job accounting information or information on the basis thereof to the job accounting client application. In this case, the latter function may not be provided.
[0028]
The second is a printer driver of a conventional printer that does not support the job accounting function. This does not have the two functions described above.
[0029]
<Details of job accounting system>
Next, the operation of each part in the configuration of FIG. 1 will be described. In particular, the operation of the job accounting client application 101 will be described with reference to the flowchart of FIG.
[0030]
A computer 1001 connected on the print network has a job accounting server application 100. The server computer 1001, the client computer 101, and the client computer 102 operate with an operation system (OS), and the OSs operating on the client computers 101 and 102 are referred to as OS1 and OS2, respectively.
[0031]
In the client computer 101, the application 101a calls an API (application programming interface) to the OS GDI 101b (graphic device interface: a system that performs graphic drawing in the OS 1).
[0032]
The job accounting client application 101e monitors (hooks) the API (step S1301 in FIG. 13). As a result, the number of times the API for instructing the page break and paper discharge is called is counted, and the number of discharged paper and the number of pages of the job issued by the application are acquired. However, the information obtained by the API hook is used when the printer driver 101c does not have a function of notifying the print job information. Since this function is provided when the printer driver supports the job accounting function, the job accounting client application 101e determines whether or not the printer driver 101c has the job accounting function (step S1302).
[0033]
If the printer driver 101c has a job accounting function and print information can be notified to the job accounting client application 101e, the information acquired by hooking is discarded (step S1304), and the information acquired by the printer driver 101c is deleted. The job accounting server application 100 is notified (step S1305). On the other hand, if the printer driver 101c does not support the job accounting function, the information obtained by the API hook is transmitted to the job accounting server application 100.
[0034]
The GDI 101b transfers the print data generated based on the print request from the application to the spooler 101d and stores it. The spooler 101 d transmits print data to the printer 103 while monitoring the status of the printer 103.
[0035]
In the client computer 102, when the application 102a calls an API to the GDI 102b and issues a print job, the printer driver 102c converts the API called by the application into print data, and transfers the print data to the system spooler 102d. To accumulate. The system spooler 102d monitors the status of the printer 103, and transmits print data to the printer 103 if the printer 103 is ready.
[0036]
The job accounting client application 102e monitors the system spooler 102d based on the API notification from the printer driver 102c, manages the print data and the job accounting information in association with each other, and outputs the number of pages or the number of pages of the print job. Get such information. The information acquisition method will be described later. Similar to the job accounting client application 101e, the job accounting client application 102e notifies the job accounting server application 100 of information obtained by hooking the API or job accounting information acquired from the printer driver 102c.
As described above, in this embodiment, the job accounting server application 100 exists in a computer connected to the network, and job accounting information acquired by the job accounting client application 102 is stored and managed by the job accounting server application 100. However, functions such as counting and managing print job information are realized by the printer 104 with the job accounting function itself when sending print data to the printer 104 with the job accounting function. As for user authentication, the authentication operation itself is performed by the printer 104, and the user interface (UI) at that time is realized by the printer driver of the printer 104 with a job accounting function.
[0037]
That is, when the user prints using the printer 104, as in the case of using a conventional printer, when the application passes data to the GDI, the printer driver of the printer 104 generates print data based on the data. To do. The print data is temporarily stored in the system spooler and then transmitted to the printer 104. The printer 104 performs printing based on the received data, and generates, stores, and manages job accounting information for each user according to the print type such as the number of pages, paper size, duplex printing, or color printing.
[0038]
In the system shown in FIG. 1, a printer 104 with a job accounting function and a conventional printer 103 without a job accounting function coexist. In such a system, even when printing is performed from the client computer using the printer 104 with the job accounting function, the job accounting client application 102e hooks the API call from the application or the data from the printer driver. By providing the job accounting information such as the number of ejected sheets or pages of the print job and sending it to the job accounting server application, the job accounting information is centrally managed by the job accounting server application It is possible. In this case, management of job accounting information in the printer 104 may be executed. That is, a plurality of job accounting systems may exist on the network.
[0039]
<Computer configuration>
Here, the hardware configurations of the client computers 101 and 101 and the server computer 1001 in FIG. 1 will be briefly described with reference to FIG.
[0040]
In FIG. 3, a computer 3000 includes a CPU 1 that executes document processing in which graphics, images, characters, tables (including spreadsheets), and the like are mixed based on a document processing program stored in a program ROM of the ROM 3. The CPU 1 comprehensively controls each device connected to the system bus 4. The CPU 1 also executes programs such as an OS including an application and GDI, a printer driver program including a procedure of a flowchart to be described later, a system spooler, and a job accounting client application, thereby realizing the above-described functions.
[0041]
The RAM 2 functions as a main memory and work area for the CPU 1. A keyboard controller (KBC) 5 controls key input from a keyboard 9 or a pointing device (not shown). A CRT controller (CRTC) 6 controls display on the CRT display 10. A disk controller (DKC) 7 controls access to an external memory 11 such as a hard disk (HD) or floppy disk (FD) that stores a boot program, various applications, font data, user files, edit files, and the like. A LAN interface (LAN I / F) 8 is connected to a local area network and executes communication control processing with devices on the network such as the printer 103, the printer 104, and other computers. The CPU 1 executes an outline font development (rasterization) process on the display information RAM set on the RAM 2, for example, and enables WYSIWYG (a function for matching display contents and print contents) on the CRT 10. . The CPU 1 opens various windows registered based on commands instructed by a mouse cursor (not shown) on the CRT 10 and executes various data processing.
[0042]
In FIG. 1, since all the printers are network printers, the computer is connected to the printer via the LAN interface 8. However, the printer has an interface such as a parallel interface or USB and is connected to the printer locally. Even if it exists, this invention is applicable.
[0043]
<Job accounting process flow>
FIG. 2 is a diagram for explaining the flow of print data transmission from the host computer in FIG. 1 to the printer 104 with a job accounting function. In FIG. 2, a computer 200 corresponds to the computer 101 or 102 in FIG. 1, and may be connected to the printer 104 via a network or directly. Here, it is assumed that the job accounting server application 100 does not exist. The printer driver corresponds to the job accounting function. Here, since Windows of Microsoft Corporation is used as an OS, a graphic device interface (GDI) is used as a graphic engine. However, if another OS is used, a graphic engine prepared for the OS is used. do it.
[0044]
The application 201, the graphic engine (GDI) 202, the printer driver 203, and the system spooler 204 exist as files stored in the external memory 11 on the host computer and the modules that use the OS and its modules when executed. Are loaded into the internal memory 2 in the host computer and executed.
[0045]
The graphic engine (GDI) 202 loads the printer driver 203 prepared for each printing apparatus into the internal memory of the computer, and sets the output of the application 201 in the printer driver 203. Print data received from the application 201 is converted into a format that can be read by the printer driver, and is output to the printer driver 203.
[0046]
The printer driver 203 issues an authentication request to the job accounting client application 205 at the start of printing. The job accounting client application 205 queries the printer 104 with the job accounting function for authentication, acquires the result, and notifies the printer driver 203 of the result. If the authentication is successful, based on the drawing data received from the graphic engine (GDI) 202, it is converted into a control command that can be recognized by the printer, for example, PDL (Page Description Language). The converted printer control command is output as print data via the system spooler 204 by the OS. When print data is sent to the printer 104 with a job accounting function, authentication information (to be described later) is added to the print data and sent. As will be described later, this authentication request destination may be a job accounting server application.
[0047]
FIGS. 4 and 5 are diagrams showing examples of information passed from the printer driver 203 to the job accounting client application 205. The information of FIG. 4 is passed for an authentication request at the start of printing. The information shown in FIG. 5 is passed as job accounting information when printing is completed. Using the notification as a trigger, the job accounting client application 102e periodically monitors the system spooler 102d as described above, and manages print data and job accounting information in association with each other.
[0048]
In FIG. 4, job information 401 includes information for identifying whether this job is sent to a printer with a job accounting function or a printer without a job accounting function, and a user ID and password to be described later. Such authentication information is included. The same applies to FIG.
[0049]
The job identifier 402 includes an identifier for associating the job accounting client application 205 with a print job submitted to the spooler.
[0050]
In FIG. 5, an API return value 403 indicates an argument passed from the job accounting client application 205 when the printer driver notifies the job accounting client application 205 of the information shown in FIG. Including.
[0051]
The total number of sheets 404 includes the total number of sheets to be discharged from the job. Based on this information, it is possible to realize job accounting that represents accounting and the like.
[0052]
Blocking information 405 changes any of the items of detailed information 406 such as designation of paper size, paper type, or N-up printing (function to print N pages in one sheet) within one print job. In this case, the information includes information indicating blocks divided for each sheet in which the items are common. If the above items do not change in one job, one job becomes one block.
[0053]
The detailed information 406 includes detailed information for each block such as double-sided / single-sided, paper type, paper size, color information, the number of pages per sheet, the number of copies, and the total number of sheets in the block.
[0054]
With this information, a more detailed job accounting function can be provided.
[0055]
As described above, the job accounting information shown in FIGS. 4 and 5 is passed from the printer driver to the job accounting client application 205, but is not used in the printer 104 with the job accounting function.
[0056]
<Job accounting user interface>
After FIG. 6, the flow of processing in the job accounting system in the printer driver 203 will be described. Here, it is assumed that the printer driver 203 is the printer 104 with a job accounting function corresponding to the job accounting function. However, the printer itself may be the conventional printer 103 as long as the printer driver supports the job accounting function.
[0057]
FIG. 6 is a graphic user interface (GUI) screen for setting the functions of the printer driver 203 in the job accounting system. This is also simply called printer setting.
[0058]
When the check box 601 in the drawing is checked ON, the printer driver 203 operates as a part of the job accounting system. On the other hand, when the check box 601 is not checked, the printer driver 203 transmits only print data regardless of the job accounting system.
[0059]
The left icon 602 is displayed in conjunction with the check box 601. This icon is displayed on all sheets (various screens displayed as GUI) owned by the printer driver, and is designed so that the user can know the setting status of job accounting at a glance.
[0060]
The check box 603 is displayed when a user having administrator authority who is permitted to set the environment of the computer performs printer setting in the OS that allows different login users to have different authority. Whether or not password information necessary for job accounting can be held for a user who uses this printer driver is determined based on ON / OFF of this check box.
[0061]
Specifically, the dialog displayed when the authentication information input button 604 is pressed differs depending on whether the check box 603 is checked ON or OFF. If the check is ON, the dialog shown in FIG. 7 is displayed. In this case, the user can input an ID 701 for specifying a department or a user as authentication information and a password 702 for the ID 701.
[0062]
On the other hand, when the check box 603 is OFF, the dialog shown in FIG. 8 is displayed. That is, the user can input only the ID 701 that specifies the department or the user as the authentication information.
[0063]
As described above, in an OS in which different authority can be set for each user, it is possible to provide a variation of security management by an administrator.
[0064]
A button 703 on the authentication information input screen in FIG. 7 is a button for inquiring whether the input ID 701 and password 702 are correct as job accounting information. When the ID 701 and the password 702 are input, it can be pressed. When the button 703 is pressed, the printer driver 203 requests the job accounting client application 205 to verify authentication information. The job accounting client application 205 sends authentication information to the job accounting server application 100 or the printer 104 with the job accounting function to request authentication.
[0065]
(Case 1) When the job accounting server application 100 exists in the system, authentication information is transmitted to the job accounting server application 100 to request authentication.
[0066]
(Case 2) When the printer driver 203 is a printer driver for the printer 104 with the job accounting function, authentication information is transmitted to the printer 104 to request authentication.
[0067]
(Case 3) When the printer driver 203 is a printer driver for the printer 104 with the job accounting function and the job accounting server application 100 exists in the system, that is, two job accounting systems exist in one printing system. In this case, the authentication information is transmitted to the printer 104 to request authentication, and the authentication information is transmitted to the job accounting server application 100 to request authentication.
[0068]
Here, it is also possible to store (cache) authentication information input according to settings to be described later, and send the stored authentication information to make an authentication request. In this way, by caching the authentication information, the authentication information inquiry time can be shortened.
[0069]
When it is determined by the inquiry that the authentication information is correct, a message shown in FIG. 9 is displayed. On the other hand, if it is determined that there is an error, the message shown in FIG. 10 is displayed.
[0070]
A check box 704 is a button that makes it possible to select whether or not to confirm authentication information during printing. When the check box 704 is checked ON, a print command is issued from the application, printing by the printer driver 203 is started, and a dialog 1101 shown in FIG. 11 is displayed immediately before print data is sent. On the other hand, when the check box 704 is OFF, the dialog 1101 is not displayed and printing is performed using the stored authentication information.
[0071]
However, even when the check box 704 is not checked, if the authentication information is not stored, the password 702 is displayed in a blank state as shown in FIG. Then, the dialog 1101 is displayed.
[0072]
In this manner, authentication information input by specifying the check box 603 can be held, and input time can be saved and authentication time can be shortened.
[0073]
In addition, by pressing the button 703, it is possible to confirm in advance whether the authentication information to be stored is correct, and it is possible to provide a method for storing correct authentication information for the user.
[0074]
As a supplementary explanation, if the password information necessary for job accounting is not retained in the check box 603, the password 702 is not retained, so the check box 704 has no meaning to be displayed, and the dialog box is not displayed. 1101 is always displayed.
[0075]
In this embodiment, authentication information that can specify whether to save or not is limited to a password, and the ID is stored unconditionally. However, it may be possible to specify whether or not to save both the password and the ID.
[0076]
If the check box 704 in FIG. 7 is turned on, the dialog 1101 is displayed for each print job, so that the user can edit the authentication information and can print using a different ID for each print. For example, when the printer driver 203 is used in an environment in which printing is performed using a plurality of IDs, authentication information is confirmed at the start of print job processing, and authentication is reliably performed for each ID. It becomes possible to make it. On the other hand, when the printer driver 203 is used in an environment where only single authentication information is used, it is possible to reduce the number of operation steps by omitting confirmation of the authentication information at the start of printing.
[0077]
In this way, by providing the check box 704, it is possible to set whether or not to confirm authentication information at the time of printing, and the number of operation steps in job accounting can be reduced. Further, it becomes easy to change the authentication information for each print job, and convenience is improved.
[0078]
When a dialog 1101 is displayed at the start of printing, authentication information is sent immediately before print data is sent by pressing an OK button 1102. As a result, if the authentication information is correct, it is determined that printing is possible, and print data is transmitted. If the authentication information is not correct, the message shown in FIG. 10 is displayed, and a dialog 1101 is displayed when the OK button 1001 is pressed. The user inputs the authentication information again, and sends the authentication information by pressing an OK button 1102.
[0079]
On the other hand, when transmitting the stored authentication information, the dialog 1101 is not displayed. If the authentication information is not correct, the message shown in FIG. 10 is displayed, and a dialog 1101 is displayed when the OK button 1001 is pressed. The user inputs the authentication information again, and transmits the authentication information by pressing the OK button 1102 again. Printing can be canceled by pressing a cancel button 1103. In this case, the printer driver application is notified of the printing failure by the printer driver 203, and does not send subsequent print data.
[0080]
<Printer setting process>
FIG. 17 is a flowchart of a processing procedure when the UI screen of FIG. 6 is displayed and setting is performed. This screen is displayed by performing an operation for a predetermined printer setting, and is executed by the printer driver here.
[0081]
First, in step S1701, the UI screen of FIG. 6 is displayed on a display monitor, for example, the CRT 10 of FIG. In step S1702, it is determined whether the user performing the operation is an administrator user who is permitted to set the print environment. If the user is not permitted to set the environment, in step S1703, the check box 603 (setting for storing authentication information) in FIG. 6 is deleted or grayed out, and the check box cannot be input. To do. Of course, on the contrary, if it is an administrator user, the check box 603 may be displayed.
[0082]
If the UI screen is displayed in this way, input by the user is awaited in step S1704, and if there is an input, the content is determined in step S1705. If the input is “OK”, the print setting input in step S1706 is saved, and the process ends. Here, the setting for saving the authentication information is made, and if the authentication information is inputted, the information is also saved. If the input is a cancel button, the input print settings are discarded and the process is terminated.
[0083]
If the pressed button is the “verify” button 703 in the screen of FIG. 7 that is opened when the setting button 604 of the printer setting screen is pressed, the button is input in the same manner as in step S1408 of FIG. Authentication information is passed to the job accounting client application and authentication is requested. If the authentication result is returned from the job accounting client application, the result is judged, and if successful, the screen of FIG. 9 is displayed as described above, and if it is unsuccessful, the screen of FIG. Tell whether or not it has been.
[0084]
If the input is other, the display screen is updated according to the input, and the input is waited for in step S1704.
[0085]
In this way, only the administrator can change the setting for storing authentication information, and the authentication information can be confirmed prior to printing.
[0086]
<Job accounting process by printer driver>
FIG. 14 is a flowchart showing the flow of job accounting processing by the printer driver described above.
[0087]
In step S1401, a print command is received from the application.
[0088]
In step S1402, it is determined whether job accounting (check button 601 in FIG. 7) is ON. If ON, the process proceeds to step S1403, and if OFF, the process proceeds to step S1411.
[0089]
In step S1403, the check button 704 determines whether to display the authentication information confirmation dialog shown in FIG. 11 at the time of printing. If so, the process proceeds to step S1405. If not, the process proceeds to step S1404.
[0090]
In step S1404, it is determined whether the authentication information is held. If the authentication information is held, the process proceeds to step S1413. If not, the process proceeds to step S1405. In step S1404, for example, the check button 603 in FIG. 5 is checked. If the check button 603 is on, it is determined that the authentication information is retained. Further, the storage area of the authentication information is further examined, and if data other than specific data such as null data is stored, it may be determined that the authentication information is held.
[0091]
In step S1405, the authentication information is set to be checked before printing is started, or the authentication information is not saved. Therefore, the authentication information confirmation dialog 1101 is displayed and the input from the user is waited for.
[0092]
In step S1406, if the user event input is a print execution request (OK button 1102 is pressed), the process proceeds to step S1407; otherwise, the process proceeds to step S1410.
[0093]
In step S1407, printing is started using the held authentication information. At this time, if the authentication information is set to be stored, the information is stored in a predetermined area of the nonvolatile medium.
[0094]
In step S1408, authentication processing is executed. Specifically, the job accounting client application 205 is notified of the information shown in FIG. The job accounting client application 205 transmits the acquired information to the job accounting server application 100 or the printer 104 with the job accounting function, and obtains an authentication result.
[0095]
The printer driver receives the authentication result from the job accounting client application. If the authentication is successful, the process proceeds to step S1411. If the authentication is unsuccessful, the process proceeds to step S1409.
[0096]
In step S1409, an authentication failure message is displayed, the user input is awaited, and the OK button 1001 is pressed to return to step S1405.
[0097]
In step S1410, it is determined whether the user event input is a print cancel request (cancel button 1103 pressed). If so, the process proceeds to step S1412. Otherwise, the next event is waited.
[0098]
In step S1411, data transmission to the system spooler is started. When the transmission is completed, it is determined in step S1414 whether or not job accounting is ON. If job accounting is ON, the information shown in FIG. 5 is notified to the job accounting client application 205 in step S1415 when printing is completed. . The job accounting server application 100 receives this information from the job accounting client application 205, and performs job accounting based on this information. If the job accounting server application does not exist in the network system, this information need not be transmitted.
[0099]
On the other hand, the printer 104 with the job accounting function performs counting inside the printer as the printing process is performed.
[0100]
In step S1412, the application is notified of print cancellation.
[0101]
If it is determined in step S1404 that the authentication information is held, the authentication information stored in step S1413 is read from the storage area into the authentication information area on the RAM, and the process proceeds to step S1408. The authentication process is performed using.
[0102]
FIG. 15 is a flowchart showing in more detail the printing process in step S1411.
[0103]
In step S1501, graphic data (data such as an image or document to be printed) passed from the graphic engine is taken in, and it is determined in step S1502 whether a new block needs to be provided. Here, when the generation of new print data is started, or the conditions included in the detailed information 406 of FIG. 5 are the double-sided / single-sided, paper type, paper size, color information, the number of pages per sheet, and the number of copies. When any one of them is changed, a new block is generated.
[0104]
In step S1503, a new block is generated. When the newly generated block is the head of a new print job, first, an area from the printer name to the blocked information 405 in FIG. 5 is secured in the memory, and the information determined at that time is the corresponding area. Write to.
[0105]
In step S1504, an area for the detailed information of the new block is secured in the format shown in FIG. 5, and the double-sided / single-sided type, paper type, paper size, color information, number of pages per sheet, number of copies, etc. Write the information defined at the time.
[0106]
In step S1505, a PDL command to be transmitted from the graphic data to the printer is generated. It is determined whether the command generated in step S1506 is a paper discharge command. If it is a paper discharge command, the number of sheets in the detailed information of the corresponding block is counted in step S1507.
[0107]
In step S1508, it is determined whether the print job is finished. If finished, the print data is transmitted to the printer by the OS, and the process is finished.
[0108]
As described above, the printer driver generates detailed job accounting information while generating print data.
[0109]
<Authentication processing by printer with job accounting function>
FIG. 16 shows an authentication processing procedure by a printer with a job accounting function. Job accounting server application
The authentication process by means of the same procedure.
[0110]
When authentication information is sent from the printer driver to the job accounting client application in step S1408, the authentication information is sent from the job accounting client application to the printer with the job accounting function. FIG. 15 starts from that point. In step S1601, the received authentication information is collated with a database of correct authentication information stored in advance. In step S1602, the result is determined. If the verification is successful, authentication success is returned to the job accounting client application in step S1603. If the verification is unsuccessful, authentication failure is returned to the job accounting client application in step S1604. Thus, the following characteristic functions are realized in the job accounting system of the present embodiment.
[0111]
(1) Since user authentication can be performed prior to printing, it is possible to prevent a situation where authentication information is found to be incorrect when authentication is performed during printing.
[0112]
(2) The administrator user can set whether to save the authentication information. For this reason, the administrator can change this setting according to the use status of the printer and the status of the entire network system to which the printer is connected. For example, for color printers with relatively high printing unit prices, authentication information must be entered every time it is used for strict management, and for monochrome printers that are relatively inexpensive and frequently used, the authentication information is stored and operated. Can be made easier. For printers shared by a plurality of departments with different account management units, authentication information can be input every time printing is performed in order to accurately grasp the account information for each department.
[0113]
(3) When saving of authentication information is set, using the saved authentication information saves the user the trouble of inputting authentication information and shortens the time required for printing.
[0114]
(4) Since the setting for inputting authentication information for each print job can be selected, the authentication information is input for each print job at a terminal used by a plurality of users regardless of whether or not the authentication information is stored. If the authentication information is set to be stored in the terminal occupied by, printing can be performed using the stored authentication information. For this reason, efficient processing can be performed for a terminal of a single user, and accurate account management can be performed for a terminal shared by a plurality of users.
[0115]
(5) Since the printer driver can generate job accounting information not only for the number of sheets, but also for double-sided / single-sided, paper type, paper size, color information, number of pages per sheet, etc., an accurate account Management is possible.
[0116]
[Second Embodiment]
In addition to the printing system including the printer and the host computer shown in FIG. 2, the printing system of the present embodiment may take a configuration in which print data from an application is temporarily spooled with intermediate code data as shown in FIG.
[0117]
FIG. 18 is an extension of the system shown in FIG. 2, and has a configuration in which a spool file 303 composed of an intermediate code is temporarily generated when a print command is sent from the graphic engine 202 to the printer driver 203. In the system shown in FIG. 2, the application 201 is released from the printing process when the printer driver 203 has converted all print commands from the graphic engine 202 into printer control commands. On the other hand, in the system of FIG. 18, the application 201 is released from the printing process because the spooler (hereinafter referred to as “spooler”) 302 in the printer driver converts all the print commands into intermediate code data and stores it in the spool file 303. It is the time of output. The latter usually requires less time. In the system shown in FIG. 18, the contents of the spool file 303 can be processed. As a result, various page handling functions such as enlargement / reduction or printing by reducing a plurality of pages into one page can be realized with respect to print data from the application. As will be described later, job combination, editing such as page switching, and data preview are also possible. Furthermore, by analyzing the data and determining color / monochrome, it is possible to achieve resource-saving printing and performance improvements that take into account printer functions.
[0118]
For these purposes, the system of FIG. 2 has been expanded to spool with intermediate code data as shown in FIG. In order to process the print data, settings are normally made from a window provided by the printer driver 203.
[0119]
Hereinafter, basic processing of the expansion method in FIG. 18 will be described. First, the dispatcher 301 receives a print command from the graphic engine 202. If the print command received by the dispatcher 301 from the graphic engine 202 is a print command issued from the application 201 to the graphic engine 202, the dispatcher 301 loads the spooler 302 stored in the external memory 11, and the printer driver 203. Instead, a print command is sent to the spooler 302.
[0120]
The spooler 302 converts the received print command into an intermediate code and outputs it to the spool file 303. In addition, the spooler 302 acquires the processing settings relating to the print data set for the printer driver 203 from the printer driver 203 and stores them in the spool file 303.
[0121]
The spool file 303 is generated as a file on the external memory, but may be generated in the internal memory. Further, the spooler 302 loads the spool file manager 304 stored in the external memory, and notifies the spool file manager 304 of the generation status of the spool file 303. Thereafter, the spool file manager 304 determines whether printing can be performed in accordance with the contents of the processing settings relating to the print data stored in the spool file 303.
[0122]
When the spool file manager 304 determines that printing can be performed using the graphic engine 202, the despooler 305 stored in the external memory is loaded, and the intermediate code described in the spool file 303 is loaded into the despooler 305. Is instructed to perform the printing process.
[0123]
The despooler 305 processes the intermediate code included in the spool file 303 according to the contents of the processing setting included in the spool file 303 and outputs the processed code again via the graphic engine 202.
[0124]
If the print command received by the dispatcher 301 from the graphic engine 202 is a print command issued from the despooler 305 to the graphic engine 202, the dispatcher 301 sends the print command to the printer driver 203 instead of the spooler 302.
[0125]
The printer driver 203 generates a printer control command and sends it to the system spooler 204.
[0126]
<Print job spooling>
Further, FIG. 18 shows an example in which a previewer 306 and a setting change editor 307 are arranged in addition to the extended system described so far to enable preview, print setting change, and combination of a plurality of jobs.
[0127]
In order to perform print preview, print setting change, and combination of a plurality of jobs, as shown by 1901 in FIG. 19, in the pull-down menu which is a means for performing “designation of output destination” in the printer driver properties, “Edit and Specify “Preview”.
[0128]
In this way, the contents set in the properties of the printer driver are stored in a structure (called DEVMODE in the Windows OS) provided by the OS as a setting file. The structure includes, for example, a setting for whether to store in the spool file manager 304 during processing settings included in the spool file 303. When the spool file manager 304 reads the processing settings via the printer driver and stores are specified, the page drawing file and the job setting file are generated and stored in the spool file 303 as described above. As shown above, the spool file manager window screen pops up, and the jobs spooled in the spool file 303 are displayed in a list. FIG. 20 shows an example in which four jobs are spooled, and a job can be operated by pressing a menu bar or a menu icon immediately below it.
[0129]
The number of operations on the menu bar and menu icon is the same. The operation type is `` Print '' (Print) with the job selected, `` Save and print '' (Proof Print) to leave the intermediate code spool file as it is, and print settings taking into account the print settings "Print Preview" to see the output preview, "Delete" to delete the intermediate code spool file, "Duplicate" to create a copy of the intermediate code spool file, multiple intermediate codes Combine the spool file jobs into a single job (Combine), split the combined job into multiple original jobs (Separate), print settings for single jobs or combined jobs (layout settings) "Change Print Settings" to change the print order of a job, "Move to-Top" to change the print order of a job, "Move to-Previous" to advance the print order by one (Move to-Previous), "Move to-Next" to slow down the print order of a job by one, Print order of a job There are more than 11 “Move to-Last” operations.
[0130]
When a preview of a single job or a combined job is designated on the spool file manager window screen (FIG. 20), the previewer 306 is loaded, and the intermediate code described in the spool file 303 is loaded into the previewer 306. Instructs the user to perform preview processing for the current job.
[0131]
The previewer 306 sequentially reads the page drawing file (PDF) of the intermediate code included in the spool file 303, processes it according to the content of the processing setting information included in the job setting file (SDF) stored in the spool file 303, and generates a graphic. A GDI function is output to the engine 202, and the graphic engine 202 outputs drawing data to its own client area, thereby enabling output on the screen.
[0132]
The graphic engine 202 can perform appropriate rendering according to the designated output destination. From this, the previewer 306 can be realized by processing the intermediate code included in the spool file 303 according to the content of the processing setting included in the spool file 303 and outputting using the graphic engine 202, similarly to the despooler 305. It becomes. In this way, the processing settings set in the printer driver are stored in the spool file 303 as a job setting file, and the data of the page drawing file is processed and output based on the job setting file, so that the actual drawing data is obtained. How to print, and if N-up (N page logical page is reduced and printed on one physical page) is specified, if double-sided printing is specified, bookbinding printing is specified If a stamp is designated, a print preview close to that output by the printer can be provided to the user accordingly. Note that the preview function of application software such as conventional document creation is drawn based on the page settings in the application, so the print settings in the printer driver are not reflected and the actual printout is performed. It was not possible to make the user recognize the preview.
[0133]
By performing the preview processing as described above, a large preview of the print processing settings included in the spool file 303 is displayed on the screen by the previewer 306 as shown in FIG. 21, and then the preview is displayed by the user's non-display instruction. The window 306 is closed, and control is transferred to the spool file manager window screen (FIG. 20).
[0134]
If the user performs printing in accordance with the contents displayed by the previewer 306, printing is performed by instructing "Print" (Print) or "Save and Print" (Proof Print) on the spool file manager 304. Issue a request. As described above, the print request is processed by the despooler 305 based on the job setting file to generate a GDI function and is transmitted to the graphic engine 202, and a print command is sent to the printer driver 203 via the dispatcher 301. And printing is performed.
[0135]
As described above, when the spool is designated in the “Edit and Preview” setting, the generated print data is stored in the spooler in units of jobs. When a plurality of spooled print jobs are selected and “combine” is designated for the selected jobs, the spooler combines the selected print jobs into one job.
[0136]
<Job accounting processing for spooled print jobs>
In the case where job accounting is performed in such a spool system, processing after print data is spooled will be described with reference to FIG.
[0137]
In step S2201, the spool file manager 304 receives an event input.
[0138]
If the event is a print command in step S2202, the process proceeds to step S2203, and if not, the process proceeds to step S2204.
[0139]
In step S2203, the spool file manager 304 activates the despooler 305 and issues a print command. In this case, the despooler 305 performs the same function as the application in FIG. Therefore, an inquiry about authentication information at the time of printing is made when a print request is made again to the printer driver 203 via the dispatcher 301. The subsequent steps are the same as those after step S1402 in FIG.
[0140]
In step S2204, if the event is a job combination request, the process proceeds to step S2205; otherwise, the process proceeds to step S2206.
[0141]
In step S2205, the selected jobs are handled as combined jobs. Specifically, a print request (the process of step S2203) is made at once for the spool files 303 of these multiple jobs by a single despooler 305.
[0142]
Note that since the print data from the application is sent to the spooler 204 by the dispatcher 301, the data is not sent to the printer driver 203 at this time.
[0143]
That is, even when a plurality of jobs are combined and printed as shown in FIG. 20, an authentication request is not made for each job before combining, but authentication processing is performed after combining the jobs into one job. It is a mechanism that is performed.
[0144]
Similarly to the operation described in the first embodiment, a processing method of the spool system when the cancel button 1103 is pressed on the authentication information input screen illustrated in FIG. 11 will be described with reference to FIG. Since this processing procedure is almost the same as that shown in FIG. 14, only the parts different from FIG. 14 are shown in FIG.
[0145]
Specifically, the processing after step S1412 in FIG. 14 is different. First, in step S1410, the print cancel command in step S2301 is notified to the despooler 305 instead of the application.
[0146]
In step S1802, the despooler 305 notifies the spool file manager 304 that printing has been canceled, and is unloaded from the internal memory.
[0147]
In step S1803, the spool file manager 304 deletes the spool file 303 generated by the spooler 302 and unloads it from the internal memory. As a result, even when the spool system is expanded in the job accounting system, job accounting is performed without the spool file being held in the external memory.
[0148]
With the above procedure, the following characteristic functions are realized in the job accounting system of the present embodiment.
(6) For a print job in which a plurality of print jobs are combined into one by a combining operation, a single authentication process is performed on the entire combined job as a single print job. Thereby, simplification of operation by the user and speeding up of printing can be realized.
[0149]
Note that the present invention can be applied to a system composed of a plurality of devices (for example, a host computer, an interface device, a league, a printer, etc.), or a device (copier, printer, facsimile device, etc.) composed of a single device. You may apply to.
[0150]
Another object of the present invention is to store a storage medium storing software program codes for realizing the functions of the above-described embodiments and realizing the procedures of FIGS. 13 to 17 or FIGS. Alternatively, it can be achieved by reading and executing the program code stored in the storage medium by the CPU or MPU.
[0151]
In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.
[0152]
As a storage medium for supplying the program code, for example, a floppy disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, a ROM, or the like can be used.
[0153]
Further, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also an OS (operating system) operating on the computer based on the instruction of the program code. A case where part or all of the actual processing is performed and the functions of the above-described embodiments are realized by the processing is also included.
[0154]
Further, after the program code read from the storage medium is written in a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, the function expansion board is based on the instruction of the program code. Also included is a case where the CPU or the like provided in the function expansion unit performs part or all of the actual processing, and the functions of the above-described embodiments are realized by the processing.
[0155]
【The invention's effect】
As described above, according to the present invention, the authentication information confirmation procedure can be flexibly changed according to the operational environment, and the user can confirm the authentication information according to the operational environment.
[0156]
In addition, the correctness of the authentication information can be determined in advance prior to printing. As a result, the operability of the authentication process can be improved.
