The XML file itself does not do anything. The QlikView NPrinting server service looks in the Source Folder for XML files with the .request file extension. If it finds one, it executes the task or report specified in the request XML file and then renames it to have a .processed file extension. It also creates a file with the same name but with a .result file extension which contains details on the success or failure of the report or task. So:
1. Check that your NPrinting Server Service is running
2. Make sure you have the Enable external requests check-box checked
3. Copy your XML file with the .request file extension to the folder specified in Source Folder
Could you use a UNC path ("\\<server>\<share>\..etc\Wealth Daily Report.nsq") or drive letter if it is on a local drive on the NPrinting server ("C:\<path>\Wealth Daily Report.nsq")? - do not use mapped drives.
