I have read everywhere about the option of silent printing (printing a PDF
document in client side )… I have implemented a silent printing servlet as
follow:
[code]
public class EitPdfPrintServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException{
System.out.println("ProductionView.EitPdfPrintServlet: In print file
Servlet processing print");
System.out.println();
String
vDocFullPath=(String)(request.getSession().getAttribute("docFullPath"));
response.setContentType("application/pdf");
PdfReader reader = new PdfReader(vDocFullPath);
try {
PdfStamper stamper = new
PdfStamper(reader,response.getOutputStream());
PdfWriter writer = stamper.getWriter();
writer.addJavaScript("this.print({bUI: true, bSilent: true,
bShrinkToFit:
true});",false);
writer.addJavaScript("this.closeDoc(true);");
stamper.close();
} catch (DocumentException de) {
de.printStackTrace();
System.err.println("document: " + de.getMessage());
}
}
}
[/code]
The issue is I need to print few PDF'S files at once, when a user clicks a
button in the server side I am merging all the pdf files into one file (I
prefer to merge the files so the user won't need to approve printing for
each PDF document), and then invoking the servlet form inside java code:
[code]
FacesContext context = FacesContext.getCurrentInstance();
EITServletUtils.mAddSessionParameter("docFullPath", vTargetFileToPrint);
String javaScriptText = "window.open('./PrintPdfServlet','_blank');";
JavascriptContext.addJavascriptCall(context,javaScriptText);
[/code]
The problem is I can't figure out how to close the document in the browser
after the document finish printing? It seems like the row
writer.addJavaScript("this.closeDoc(true);");
Is useless! Off course I will be more satisfied if I can some how avoid from
the user to view the pdf document!
Hope to get some ideas, Thanks, Natalie
