operate and stay on the page - asp.net-mvc-3

Question

I'm building an ASP.NET MVC3 application in which I print some files. Here's the code part I do the printing:
public ActionResult Barcode(string DocumentID)
{
barkod = new Barcode(DocumentID);
MemoryStream ms = new MemoryStream();
barkod.image.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
Print(barkod);
return Redirect("Home/Index");
}
This could be silly, but how can I only do the printing and do nothing else here, no redirection or anything else?
I tried EmptyResult and returned null, but it gave me blank page.

Since it seems you do not want to return a view then why not call it via ajax:
$.post('#Url.Action("Barcode")', { DocumentID : docId }, function(result) {
});
you can also include the controller name (e.g. SomeController):
$.post('#Url.Action("Barcode","Some")', { DocumentID : docId }, function(result) {
});
If the print action will not take long or if you just want to return a status whether it takes too long or not:
public ActionResult Barcode(string DocumentID)
{
// do your thing here
return Json(the_status_a_boolean_or_some_other_type);
}
and on your js:
$.post('#Url.Action("Barcode","Some")', { DocumentID : docId }, function(result) {
if (result) {
console.log("it's a success!");
}
else {
console.log("something wrong went bad");
}
}).error(function() {
console.log('post action cannot be completed');
});
