Redirect in new browser windows

[eluser]Unknown[/eluser]
Hi.

I have little problem with redirecting in new windows.

I can use target in form or anchor as popup window, but i need make redirecting my content in new browser after some code checking:

Code:

if ($this->form_validation->run('bills') == FALSE) {
//...
Show form errors in some windows
//..
} else {
redirect("invo/bill_print"); //This I need show in new windows.
}

It is possible?
