     FIELD OF THE INVENTION 
     The present invention relates generally to the field of mail piece and/or parcel weighing and processing in a network; and, more specifically, to the field of printing an indicia for mailing or shipping through the use of an internet or intranet data processing environment. 
     BACKGROUND OF THE INVENTION 
     Systems that allow the user to process parcels for delivery by a carrier are known as shipping systems; or, if the intent of the system is to allow the user to choose from among the services of more than one carrier, the system may be known as a carrier management system. By whatever name, these systems (hereinafter referred to as “shipping systems”) are designed to prepare parcels in accordance with the regulations of the carrier that will be picking up the parcels for later delivery. 
     Traditional configurations of shipping systems include low-end embedded systems, mid-range personal computer (PC) based systems, and upper end mid and main frame based systems. 
     Embedded systems, where the shipping application is embedded within a shipping scale, generally include PROM-based rating tables and their associated functionality. Data entries to the application are made via an operator keypad on the front of the scale or by scanning bar codes or similar symbology directly to certain fields within the application. Table data and certain rating functionality is generally added through the use of PROMs. The embedded systems are generally capable of producing a manifest for use by the carrier, as well as producing barcode or address labels for application to the parcel. These systems might also interface to a postage meter for producing proof of payment for a carrier such as the United States Postal Service. 
     PC-based systems are more flexible then embedded systems because they allow a greater range of peripherals, greater memory capacity, networking capabilities (both internet and intranet) and the ability to store records and address lists while accepting data download in a variety of ways. Rating and services functionality are also directed from the application, while the system shops for an appropriate rate from a database within a memory contained within the PC or from a rating table directed by a server. Address lists can be stored or forwarded as well. The ability of the PC-based system to provide a communications link to a network, while allowing integration with a client&#39;s information systems, is perhaps the greatest strength of these systems. Network links via the internet provide the system with an interface to a great number and variety of carrier web sites, increased functionality, and parcel tracking. Additionally, data relevant to shipping history for a particular location, or historical manifest data can be downloaded or uploaded in a quick and efficient manner as necessary. These systems too can also be interfaced to postage, meters for proof of payment. 
     The PC-based systems offer much the same functionality as the upper end mid and main frame systems. The upper systems, however, offer the advantage of exceptional processing speed while handling large volumes of. transaction data or performing multi-tasking of application services, as well as application level integration with client systems. 
     Parcel shipping, in general, has benefitted from efficiencies associated with PC-based systems. Labels can be printed at the desktop, weighing scales are interconnected to PCs for inputting weight to parcel shipping applications, and manifests for recording the details of parcel pickup and delivery are printed at the desktop as well. Peripherals such as postage meters for payment evidencing, scanners, and other input devices can also be added for increased data delivery. 
     In a PC-based environment that is serving as a stand alone system only, or that is part of a local area network (LAN), or even a wide area network (WAN), the use of a postage meter to create a proof of payment becomes an important aspect. However, in an internet-based environment, there is currently no way to show proof of payment while using an internet browser for internet-based applications being directed from a server. Traditionally, the method for producing a postage indicia while using the browser has involved the use of manual meter tripping. Therefore, a method and system are required that allows the system user to control the postage meter directly from the internet-based application while utilizing a browser. 
     Based on the aforementioned needs in the art, it is an object of the present invention to trip a postage meter or execute a print indicia command that is resident on, or dependent upon, an internet link (or similar network-based link) utilizing a browser. 
     SUMMARY OF THE INVENTION 
     According to the invention, the object is achieved and the disadvantages of the prior art are overcome by a method and system for tripping a postage meter from a browser under control of a carrier management application in a data processing system. The data processing system comprises a client node in communication with a provider server, wherein the tripping of the postage meter causes an indicia to be printed by the postage meter. The client node can be one of a plurality of client nodes that are linked to the data processing system and wherein any one or more of such nodes has a postage meter for printing an indicia onto a label or a mailpiece. The indicia being indicative of the cost for shipping the parcel or mailpiece. 
     The method begins with a system user logging onto a carrier manager application web site, through a web browser. The system user requests that the web site download a set of programs from the web site to the client node. The programs are installable on a personal computer located at the client node and are for establishing control of the postage meter by the client node under direction of the carrier management application; they include an automation server and a postage meter driver. The programs are then installed on the personal computer at the client node and used in configuring the postage meter. 
     Downloading of the automation server and the postage meter driver further comprises the steps of installing and configuring the automation server and the postage meter driver at the client node. The installation and configuration preclude the necessity for repeating the download for future transactions utilizing the postage meter in conjunction with the web site. The postage meter is configured through the web site by identifying a set of characteristics of the postage meter; and, downloading the postage meter driver from the web site to the client node in accordance with the set of characteristics. Each of the above installation and configuration steps is saved as an initiation set to a memory resident in;either the provider server or the client node so that the initiation set may be called by the client node to establish the initiation set. 
     After installation, the system user tests the communication link between the postage meter and the client node prior to logging onto the carrier management application at the web site. 
     Once the postage meter is configured, the system user logs onto the carrier management application and enters a set of application parameters representative of the parcel or a mailpiece to be shipped. The set of application parameters further comprises a destination, a class or type of service by which the parcel or mailpiece will be shipped, and a desired period of time for a delivery of the parcel or mailpiece. Additionally, the parameters include a weight measurement which is entered into the carrier management application for the purpose of obtaining a cost of shipping the parcel or the mailpiece; the cost is determined as a function of the weight and the set of application parameters. Once the carrier has been identified, a trip signal or print indicia command (in the case of IBIP based indicia printing) is sent to the postage meter, through the web browser, automation server, and meter driver, wherein the trip signal or print indicia command is representative of the transaction cost. 
     The system of the present invention includes a web site for the provider server. The web site further comprises provider web pages and JAVA script functionality resident in the provider web pages for linking with a postage meter driver resident at the client node. The script functionality further comprises a set of instructions for performing one or more activities; display functionality for displaying the cost in a particular format; a “carrier selection” function for directing the cost to be transmitted to the carrier management application; and, a setup function for storing a set of steps to be used for activating: the script functionality, postage meter driver interface functionality, and the postage meter server. 
     The postage meter at the client node further comprises: the postage meter itself; a postage meter server resident at the client node and callable under control of the script functionality; and, script activation capability for allowing the script at the client node to link with the postage meter by utilizing the postage meter driver. 
     The system also has a communications link for linking the web site and the postage meter at the client node. The communications link further comprises: a browser for accessing the web site by the client node; a network interface routine for allowing access to the network where the web site resides; and, communications means for physically interfacing the postage meter with the client node and allowing tripping of the postage meter, or acceptance of the print indicia command. The system further includes selection means for selecting the cost for shipping of the mailpiece; this selection causes the postage meter to trip, thereby causing the indicia to be printed.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Beginning with FIG. 1A, there is shown a block diagram of the system of the present invention showing the flow between each of the high-level components of the system. A system user, who has a parcel, a mailpiece, or an article to be shipped via a carrier, accesses the overall system through subsystem  20 . 
     Subsystem  20  is shown as a node which includes a personal computer for processing data and running certain software applications, a monitor for providing a human interface with the personal computer so as to view screens established by the application, and a keyboard for data entry. A network or modem link is also included that will allow access to interface  15 . Interface  15 , in the preferred embodiment, is an internet link; but, it is contemplated that the link could be any intranet or hardwired communication solution requiring a browser entry. Additional peripherals that are anticipated include a scanner for scanning barcodes and similar data, a weighing scale  30  for inputting weight to the server-based shipping application, and a postage meter  40  for printing an indicia to a label or directly to a mail piece surface. The weighing scale  30  is linked to subsystem  20  via communication link  25  which is preferably a hardwire, serial communication link. The postage meter  40 , such as those available from Pitney Bowes Inc. of Stamford, Conn. is linked to subsystem  20  via communication link  35  which is preferably a hardwire, serial communication link. 
     Interface  15  links subsystem  10  with subsystem  20 . Subsystem  10  is a remote server which hosts the web site for determining a rate for shipping a parcel or mailpiece in accordance with parameters established in the carrier management application hosted by subsystem  10 ; a weight parameter is returned from weighing scale  30  through communication link  25  to subsystem  20  before entry into the shipping application. 
     Turning to FIG. 1B, there is shown a network consisting of multiple client nodes  60 ,  70 ,  80 , and  90  wherein each node is linked to a common server  50 . Each of client nodes  60 ,  70 ,  80 , and  90  is shown as a node which includes a personal computer ( 61 ,  71 ,  81 ,  91 ) for processing data and running certain software applications, a monitor ( 63 ,  73 ,  83 ,  93 ) for providing a human interface with the personal computer so as to view screens established by the application, and a keyboard ( 62 ,  72 ,  82 ,  92 ) for data entry. A network or modem link is also included (though not shown) that will allow access, through a communications link ( 66 ,  76 ,  86 ,  96 ), to the corresponding modem of server  50 . The communications link, in the preferred embodiment, is an internet link; but, it is contemplated that the link could be any intranet or hardwired communication solution requiring a browser entry. Additional peripherals that are anticipated for each of client nodes  60 ,  70 ,  80 , and  90  include a scanner for scanning barcodes and similar data, a weighing scale ( 64 ,  74 ,  84 ,  94 ) for inputting weight to the server-based carrier management application, and a postage meter ( 65 ,  75 ,  85 ,  95 ) for printing a postage indicia to a mail piece or to a tape. 
     In FIG. 2, there is shown a relationship diagram that illustrates the relationship of the system elements. 
     Subsystem  100  is representative of the client node functionalities that together interface with a provider server  104  through the use of JAVA script  108 . Through a client node, the system user utilizes a web browser, at element  102 , to connect with a provider  104  web page  106  having certain downloadable elements. The provider web page  106  is a Hypertext Markup Language (HTML) page that contains JAVA script. These elements include active server pages that can be downloaded to the client node as required. HTML is known in the art and a detailed description of its architecture and implementation is not required for an understanding of the present invention. 
     The provider web site  104  comprises a carrier management application (similar in functionality to the none-web-based ASCENT™ carrier management system which is commercially available from Pitney Bowes Inc. of Stamford, Conn.) for preparing parcels or mailpieces to be shipped. The application further comprises either rating functionality or means of accessing remote rating functionality or related services; in addition, the application might have carrier selection functionality for selecting a carrier from among two or more carriers. The selection is based upon factors that include rates, class of services, time of pickup or delivery, tracking capabilities, etc. Parcel preparation might include production of labels, production of a carrier manifest representative of the transactions that the system user has with a particular carrier, printing of postage if the selected carrier is the United States Postal Service (USPS), and determination of the shipping parameters required or desired for the shipping of the parcel or mailpiece. The parameters include destination zone or location, desired time and/or date of delivery, and whether or not any special services are connected with the 
     The client node can be one of a plurality of client nodes as is shown in FIG. 1B, or simply a single node as is shown in FIG.  1 A. The client node includes a personal computer for processing data and running certain software applications, a monitor for providing a human interface with: the personal computer so as to view screens established by the application, and a keyboard for data entry. A network or modem link is also included that will allow access to the internet. The link, however, could be any intranet or hardwired communication solution requiring a browser entry. Additional peripherals include a postage meter for evidencing payment, a scanner for scanning barcodes and similar data, as well as a weighing scale for inputting weight to the application. The weighing scale and/or postage meter is linked to the subsystem via a communication link which is preferably a hardwire, serial communication link. 
     The internet link connects the system user&#39;s entry to the internet at step  102  with provider web pages  106  that are being posted by the provider server at  104 . JAVA script  108  is contained within the web page and is used to connect the meter server  110  on the client side and to make the meter server  110  available for client use in conjunction with the meter driver  112  and communication with the postage meter  114 . The method by which this relationship is further defined is shown in the flowcharts of FIG.  3  and FIG.  4 . 
     Turning to FIG. 3, there is shown the flowchart of the method of the present invention from client initiation to preparation for logging onto the carrier management application presented by the provider server. 
     The method flow begins at step  120  where the client logs onto the provider&#39;s carrier management application web site by utilizing a browser for internet entry. Browsers are known in the art and a detailed discussion of them is not necessary for an understanding of the present invention. From step  120 , the method advances to step  122  where the system user selects several programs to be downloaded from the web site; these include an automation server, the meter driver that corresponds to the postage meter being employed at the client node, and any “plug-ins” that might be required for communication patching by the web browser. The programs are downloaded to the client node where they are saved for continued future use. 
     Plug-ins are Dynamic Link Libraries (DLL) that meet specifications defined by the web browser. DLLs are used to extend the functionality of the web browser beyond the capabilities built into their architecture by the browser developer. JAVA script will run, start its activation procedure, and then connect with the meter server on the client side to make the meter available for client use and as an output from the carrier management application. The JAVA script can communicate with the Active-X automation server directly when using INTERNET EXPLORER™ as the browser for entry to the internet; however, when using a browser, such as NETSCAPE™, a NETSCAPE “plug-in” is needed on the client side so that the JAVA script can communicate with the automation server through the plug-in. The plug-in serves as a communication patch through which the automation server “talks” to the JAVA script. Once the connection to the postage meter has been completed, the data from the postage meter can be either automatically or manually transferred back to the carrier management application to update the required logs or postage tracking routines. The information is then saved as an initiation set to a memory resident in the provider server or a client node, wherein the initiation set may be called by the client node to establish the initiation set. 
     Active-X is a set of integration technologies that enables software components to inter-operate in a networked environment using any programming language. Active-X controls are individual components that have a specific function (i.e., displaying a list box, displaying a command button, specified time delays, etc.) that when used together can create navigation tools and complete on-line applications. Active-X provides support for a wide-range of tools which include MICROSOFT® VISUAL BASICT™. Active-X is known in the programming arts and a detailed description of Active-X is not required for an understanding of the invention at hand. A detailed discussion of a method and system for establishing a standard peripheral server can be found in U.S. Pat. No. 6,282,590, and its teaching is incorporated herein by reference. 
     JAVA script, on the other hand, is a non-compiled programming language that is included in web pages and are run with a client web browser. JAVA script can perform a number of functions that benefit the ability of the provider server to download a trip signal to the postage meter through the browser. These functions include: the ability to read a rate from the appropriate field of the carrier application and to define it in terms of a selected currency ($ per transaction); the “get rate” instructions; automatic or manual trip of the postage meter; instructions to register the meter trip; communication setup; the ability to look for, and print, multiple indicias; the ability to post error messages to the client and/or the system; and, the parameters for conducting a system test of the communication link between the postage meter and the client node. 
     Returning to step  122 , after download, the programs are installed at the client node and all future calls for the automation server will come from the client node. From step  122 , the method advances to step  124  where the INSTALL routine is run before advancing to step  126  where the postage meter is configured by choosing a postage meter type and a communication port. As a part of configuration, three activities occur essentially simultaneously that prepare the client node for communication with the postage meter; these activities occur at steps  128 , 130 , and  132 . At step  128  the Active-X automation server is activated at the client node, is called under the control of JAVA script at step  130 , and the meter type and communication port are selected at step  132 . The method then advances to step  134  where the client tests the communication link with the postage meter. If the communication test is successful, then the system user logs onto the carrier management application at step  136 . 
     FIG. 4 is a flowchart of the method of the present invention from carrier management application login to reading of the rate from the required fields of the application via the browser before printing the postage in the form of an indicia. 
     At step  150 , the system user, or “client,” logs onto the carrier management application of the provider server. From step  150 , the method advances to step  152  where the client places the parcel or mailpiece to be shipped on the weighing scale to be weighed. The method advances to step  154  where the weight is input to the carrier management application through a manual entry or though a web browser as described in related U.S. Pat. No. 6,356,882. The method then advances from step  154  to step  156  where the system user enters shipping parameters under prompt from the shipping application. These parameters may include: choice of carrier; class of service; parcel dimension (for dimensional weighing requirements); special handling instructions; destination codes and addresses; an addressee; delivery instructions; and, time parameters. The method then advances to step  158 . 
     At step  158  the application runs a rate determination routine within the bounds of the selected parameters. Then, based upon the parameters entered into the application at step  156  and the rate determination of step  158 , a carrier is selected at step  160 . If the carrier is the USPS, it would be desireable to print postage in the form of an indicia based upon a trip command downloaded through the browser. In addition, any carrier that provides for a label or similar indicia having evidence of payment would find the triggering of a meter or similar device though the browser advantageous. 
     The method advances from step  160  to step  162  where the rate is applied to the carrier application before advancing to a query at step  164 . At step  164 , the method queries as to whether a transaction cost in the form of postage, or similar evidence of payment, is to be downloaded to a meter. If the response to the query is “NO,” then the method advances to a further query at step  172  which seeks to determine if the application parameters are to be re-entered, If the response to the query is “YES,” then the method re-enters the method flow at step  156 ; however, if the response to the query at step  172  is “NO,” then the method advances to step  176  where the system user quits the routine. 
     Returning to the query at step  164 , if the response to the query is “YES,” then the method advances to step  166  where the meter is tripped through the browser and an indicia is printed to a label or directly to the mailpiece. Upon tripping the meter and/or printing the indicia, the meter register is decremented or incremented at step  168  as required. Additionally, a successful/not successful response from the meter gives the system user an indication of funds status. An entry, at step  170 , to a log or manifest at the web site is then made which is representative of the printed postage or value expended. From step  170 , the method advances to the query at step  174  which asks whether or not a next parcel or mailpiece is to be processed. If the response to the query is “NO,” then the method advances to step  176  where the system user quits the routine. If, however, the response to the query at step  174  is “YES,” then the method re-enters the method flow at step  152 . 
     While certain embodiments have been described above in terms of the system within which the method may reside, the invention is not limited to such a context. 
     In the foregoing specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative rather than a restrictive sense.
