Silently Print a PDF When It Loads (Automatically Print)

Spent a long time searching for this feature... it's called Silent Print. PDFs can have javascript embedded to print. Here's how to do it in a JSP:

Note tha the secret sauce is to get a writer and then add javascript to it like so: writer.addJavaScript("this.print(false);", false);

<%@page import="java.io.ByteArrayOutputStream,
 java.io.IOException,
 java.io.*,
 javax.servlet.ServletException,
 javax.servlet.ServletOutputStream,
 javax.servlet.http.HttpServlet,
 javax.servlet.http.HttpServletRequest,
 javax.servlet.http.HttpServletResponse,
 com.lowagie.text.Chunk,
 com.lowagie.text.Document,
 com.lowagie.text.DocumentException,
 com.lowagie.text.pdf.PdfWriter"%><%
   
 Document document = new Document();
        ByteArrayOutputStream baos = new ByteArrayOutputStream();

        try {
            PdfWriter writer = PdfWriter.getInstance(document, baos);
            document.open();
            writer.addJavaScript("this.print(false);", false);
            document.add(new Chunk("Silent Auto Print"));
            document.close();
         } catch (DocumentException e) {
            e.printStackTrace();
         }

         response.setContentType("application/pdf");
         response.setContentLength(baos.size());
         File f = new File(application.getRealPath("/js.pdf"));
         OutputStream pout = new BufferedOutputStream(new FileOutputStream(f));

         baos.writeTo(pout);
%>
