Manage Pdf Rep in order to go, once done, back to same form

I have a report that works and when it finishes download a pdf document. It starts clicking a button that redir to pdf_report application.
I would like to close the pdf page (that one of PDF report) once it has finished to download the pdf document and return back to form with the button.
Within button I can do “Target” --> Other windows but it is not the same I want to do. I means that user see a blank page and it’s not obvious that he has to close the page to see back the form.

Within the PDF Report application On Footer is possible to write something that close the page once the document has been downloaded ?
