Description

The present invention relates to a form printing web service system that prints data of a computer terminal connected to a network, and more particularly to a form printing web service system that shortens a printing start time.

  Printing data of business management software (business management software is business software necessary for business execution of a company and refers to sales management software, financial management software, salary management software, asset management software, labor management software, etc.) For example, a large amount of data of 100 pages or more may be printed. In a standard web application printing process, all pages are generated in the server process, and then the generated data is transmitted to the client terminal. Therefore, when printing such a large amount of data, it takes time to print. Therefore, as a technique for shortening the printing time, an invention of a printing control apparatus that reduces the amount of data to be transmitted by transmitting only a portion (difference) different from the previous page when printing, and shortens the printing time itself has been made. Is disclosed in Patent Document 1 below.

JP-A-7-172022

  However, even if the technical idea as described above is used, it does not change that all pages are first generated as print data and then transmitted to the client terminal. Therefore, until the print start time for the first page is reduced. I can't. In addition, since a larger amount of data is transmitted at a time, the network traffic increases significantly during this time, and the response of the entire network is delayed.

  Therefore, the present inventors have invented a form printing web service system that realizes further shortening the printing start time than before.

The invention of claim 1 is capable of transmitting and receiving data via a network with a client terminal used for a user to use business management software as a web application and a database server storing a database used in the business management software. The form printing web service system, wherein the form printing web service system receives, as a print data acquisition request, a print condition indicating which data is to be printed upon receiving a print selection notification to execute printing from the client terminal. A print data acquisition unit that transmits to the database server, acquires print data corresponding to the printing conditions from the database server , and stores the print data in the storage unit; and the first of the print data stored in the storage unit print data of the specific unit After transmitting to the client terminal after the generation of the print data of a form format extracted from the storage means is the next request to print data of the specific unit that is transmitted to the client terminal from the client terminal when receiving the print request transmission, among the print data stored in the storage means, to the client terminal the next print data for a specific unit in the After generated as print data of a form format extracted from the storage means a print data sequentially transferring means, and have a, the client terminal performs a printing process of print data of a document format of a predetermined unit received from said form printing web service system, printing of a form format this received If the data is not the last print data, the print request is sent to the form print web service system. Having a print requesting unit for a form printing web service system.

  According to the present invention, instead of starting the printing process after all the data to be printed is transmitted to the client terminal as in the prior art, the data to be printed is sent every predetermined unit (for example, every page, every 10 pages). In parallel with the transmission to the client terminal and the printing process being performed at the client terminal, it is possible to send the next predetermined unit of print data. As a result, it is possible to shorten the time until the start of printing.

In addition , print data that is not in the form format stored in the storage unit can be sent to the client terminal after being converted into the form format.

  Data to be printed may be acquired from a database server.

Further, by sending a print request from the client terminal, the form print web service system can send print data in the form of the next predetermined unit using that as a trigger.

According to each of the above-described inventions, the printing start time can be further shortened than before, and the data to be printed can be distributed, so that it is possible to prevent a decrease in network response.

  An example of the system configuration of the form printing web service system 1 of the present invention is shown in the system configuration diagram of FIG. The form printing web service system 1 includes a print data acquisition unit 6, a storage unit 7, and a print data sequential transfer unit 8. Further, data can be transmitted / received to / from the client terminal 2 and the database server 4 via the network 5. The network 5 may be any of an open network such as the Internet, a closed network such as a LAN, an intranet that is a combination thereof, and may be either wired or wireless.

  When the print data acquisition unit 6 receives a print selection notification to execute printing from the client terminal 2, which data (which page, which part, which column / item, etc. of the business management software) is to be printed The print condition is transmitted to the database server 4 as a print data acquisition request. Data corresponding to the printing conditions (print data) is received from the database server 4 and stored in the storage unit 7.

  The storage means 7 is means for storing the print data received from the database server 4 by the print data acquisition means 6 in a memory, a hard disk, other internal or external storage device, and the like.

  After receiving the print request from the client terminal 2, the print data sequential transfer unit 8 receives print data of a predetermined number of pages (for example, a small number of pages such as one page, two pages, etc.) from the storage unit 7. This is a means for extracting, generating so as to be printable in a form format, and transmitting it to the client terminal 2. If the print data acquired by the print data acquisition unit 6 is already in the form format and can be printed as it is, the print data sequential transfer unit 8 does not generate the form format and transmits it to the client terminal 2 as it is. May be.

  The form format is a form output by business management software including sales, finance, and salary management, and is a format in which input data is arranged according to items and positions designated in advance. For example, the sales performance table shown in FIG. 3 (FIG. 3A is an example of a customer-specific sales performance table, FIG. 3B is an example of a product-based sales performance table), and the total balance shown in FIG. Data that displays data in a list format, such as a trial calculation table, a salary statement (a document that describes details of salary paid to employees, etc.) shown in FIG.

  Other examples of forms include sales slips used for sales paperwork, billing statements that are detailed documents of billing details for the other party, a payment list that is a table summarizing payment details for the payee, Purchase list, which is a table summarizing the contents of purchase, payment details, which is a document detailing the purchased goods, inventory list, which is a table summarizing the stock status of goods, and monthly salary payments for employees Withholding slip, which is a document indicating that tax is deducted from it, general ledger, which is a book document for posting data entered in journals by account, and manufacturing cost, which is a schedule attached to the income statement There is a description, etc.

  The client terminal 2 is a client terminal 2 in which an employee or the like actually uses business management software, and is connected to a printer 3 that prints data (the connection with the printer 3 is a network connection instead of a direct connection). It is a terminal that can print data with the printer 3, and has a print selection notification means 9, a print request means 10, and a print processing means 11.

  The print selection notification means 9 prints a predetermined page (for example, from 1 page to 100 pages) from the job management software on the client terminal 2 side, and is a notification that prints the first predetermined number of pages. Is transmitted to the form printing web service system.

  The print request unit 10 receives the first print data from the form print web service system 1, performs the print process in the print processing unit 11, and then prints the request to transmit the next print data to the client terminal 2. This is means for transmitting a request to the form printing web service system 1.

  The print processing means 11 is means for transferring the print data received from the form printing web service system 1 to the printer 3 and executing printing.

  The database server 4 is a server that stores a database used in the business management software. The data is sent to the client terminal 2 via the form printing web service system 1 equipped with the server-side function of the business management software. Send to. For example, when the business management software is salary management software, data relating to employee salaries is stored, and in the case of work management software, data relating to work such as employee turnover and holidays are stored.

  Next, an example of the process flow of the present invention will be described in detail with reference to the flowchart of FIG. 2 and the system configuration diagram of FIG.

  A user who uses the business management software on the client terminal 2 selects which range of the business management software is to be printed on the client terminal 2. In this case, for example, printing from page 1 to page 100 is selected by the business management software. When this selection is made, the print selection notification means 9 of the client terminal 2 transmits a print selection notification indicating which range is to be printed to the form printing web service system 1 (S100).

  The form printing web service system 1 that has received the print selection notification from the client terminal 2 uses the print data acquisition unit 6 as a print data acquisition request with the print condition of which data (for example, data from page 1 to page 100) is to be printed. The data is transmitted to the database server 4 (S110).

  Upon receiving the print data acquisition request, the database server 4 extracts data that matches the condition (S120) and transmits it to the form printing web service system 1.

  When the print data is acquired from the database server 4, it is temporarily stored in the memory, hard disk, external storage device or the like of the storage means 7 (S130). Then, among the stored print data, print data of a predetermined unit number (for example, the first page, the first 10 pages, etc.) is transferred from the form print web service system 1 to the client terminal 2 as a print data sequential transfer means 8. Is transmitted (S140).

  If the print data received from the database server 4 is only data and is not formed as a form to be printed, it may be generated as a form in a predetermined form and then sent as print data in S140. .

  The print processing means 11 of the client terminal 2 that has received the print data from the form print web service system 1 issues a print execution command for printing the print data with the printer 3 (S150). Printing processing of the first unit of print data received from the system 1 is started (S160).

  If the print data transmitted in S140 is not the last print data (S170), the print request unit 10 sends the next print data to the client terminal 2 in parallel with the print processing in the printer 3 in S160. A print request is transmitted so as to be transmitted (S180).

  For example, if the predetermined number of units in S140 is one page, only the first page of print data selected by the client terminal 2 in S100 is transmitted first in S140. In parallel with the start of the first print processing in S160, the print request means 10 transmits the next unit number, that is, the print data of the second page as a print request so as to transmit to the client terminal 2. It becomes.

  The print data sequential transfer means 8 of the form printing web service system 1 that has received the print request from the client terminal 2 extracts the print data of the next unit number (second page in the above example) from the storage means 7, and again the client It transmits to the terminal 2 (S190).

  In this way, each time the printing process for each unit number is performed until all the print data selected in S100 has been printed, the next unit number of print data is extracted from the storage means 7 and is sequentially transferred to the client terminal. 2 to send. If all the print data has been printed (S170), the printing process is terminated (S200).

  Conventionally, when printing is performed at the client terminal, since all the print data is transmitted to the client terminal 2 and the printing process is started, a large amount of data is printed as in the case of printing 100 pages, for example. In some cases, it took time until the first printing. However, as in the present invention, instead of first transmitting all the data to be printed to the client terminal 2, printing processing is performed in a predetermined number of units (each page, every 10 pages, etc.). In parallel with this, the time required for the first printing can be reduced by transmitting the next unit number, that is, performing sequential transmission. Further, by performing sequential transmission, the amount of data transmitted from the form printing web service system 1 to the client terminal 2 can be distributed, so that the load on the network 5 is also distributed and the network is stabilized.

  Next, the process flow of the form printing web service system 1 of the present invention will be described using a specific example.

  It is assumed that the user using the business management software on the client terminal 2 performs printing from the 50th page to the 500th page in the salary statement shown in FIG. In this case, the user using the client terminal 2 selects the client terminal 2 to print pages 50 to 500 of the business management software. When this selection is made, the print selection notification means 9 of the client terminal 2 transmits to the form printing web service system 1 a print selection notification in which printing from the 50th page to the 500th page is selected ( S100).

  Upon receiving the print selection notification from the client terminal 2, the form print web service system 1 transmits the print conditions from the 50th page to the 500th page as a print data acquisition request by the print data acquisition unit 6 to the database server 4 (S110). ).

  Upon receiving the print data acquisition request, the database server 4 extracts data that matches the 50th to 500th pages from the business management software that performs salary management (S120), and sends it to the form printing web service system 1. Send.

  When the print data (data from the 50th page to the 500th page of the salary statement) is acquired from the database server 4, it is temporarily stored in the memory, hard disk, external storage device or the like of the storage means 7 (S130). Of the stored print data, print data of a predetermined number of units (here, 10 pages are a predetermined unit number) from page 50 to 10 pages, that is, from page 50 to page 59. The print data sequential transfer means 8 transmits the print data from the form printing web service system 1 to the client terminal 2 (S140).

  If the print data received from the database server 4 is only data and is not formed as a form to be printed, it may be generated as a form in a predetermined form and then sent as print data in S140. .

  The print processing unit 11 of the client terminal 2 that has received the print data for the first 10 pages (50th page to 59th page) from the form printing web service system 1 executes printing for printing the print data by the printer 3. A command is issued (S150), and the printer 3 starts printing processing of print data for the first 10 pages received from the form printing web service system 1 (S160).

  In addition, since the print data transmitted in S140 is not the last print data (S170), in parallel with the print processing in the printer 3 in S160, the print request means 10 performs the next predetermined unit number of 10 pages. A print request is transmitted so as to transmit the print data to the client terminal 2 (S180).

  In the case of the above example, since the predetermined unit number is 10 pages, the print request unit 10 transmits to the client terminal 2 as a print request so as to transmit the print data for the next 10 pages to the client terminal 2.

  Upon receiving the print request for the next 10 pages from the client terminal 2, the print data sequential transfer means 8 of the form printing web service system 1 receives the next unit number from the storage means 7 (in the above example, the 60th to 69th pages). ) Is extracted and transmitted to the client terminal 2 again (S190).

  In this way, the print data of the next unit number is extracted from the storage unit 7 every time the print processing of each unit number is performed until all the print data selected in S100 (that is, the 500th page) has been printed. , It is sequentially transmitted to the client terminal 2. If all the print data (500th page) has been printed (S170), the printing process is terminated (S200).

  Each means in the present invention is only logically distinguished in function, and may be physically or practically the same area.

  In implementing the present invention, a storage medium storing a software program for realizing the functions of this embodiment is supplied to the system, and the computer of the system reads and executes the program stored in the storage medium. Of course.

  In this case, the program itself read from the storage medium realizes the functions of the above-described embodiments, and the storage medium storing the program naturally constitutes the present invention.

  As a storage medium for supplying the program, for example, a magnetic disk, a hard disk, an optical disk, a magneto-optical disk, a magnetic tape, a nonvolatile memory card, or the like can be used.
