Working fine now.
Thanks !! :-)

After Implementing the scripts , it throws an error like

Error: Invalid PDF: startxref not found
at process.<anonymous> (E:\V2\jsReport\node_modules\script-manager\lib\worker-processes.js:55:23)
at process.emit (events.js:200:13)
at emit (internal/child_process.js:876:12)
at processTicksAndRejections (internal/process/task_queues.js:84:9)

And the following is our jsreport.config file

{

"allowLocalFilesAccess": true,
"store": {
    "provider": "fs"
},
"blobStorage": {
    "provider": "fs"
},
"templatingEngines": {
    "timeout": 600000
},
"chrome": {
    "timeout": 600000
},
"extensions": {
    "authentication" : {
        "cookieSession": {
            "secret": "<your strong secret>"
        },
        "admin": {
            "username" : "admin",
            "password": "password"
        },
        "enabled": false
    },
    "sample-template": {
        "createSamples": true
    },
    "scripts": {
	"allowedModules": "*",
     "timeout": 30000
    },
	"express": {
        "inputRequestLimit": "200mb"
    },
	"fs-store": {
   "syncModifications": false
}
}

}

We have settings where user can enter the number of copies to printed in same PDF.
Is it possible in JS Report ?
If so ! please suggest us an idea .
