c# webBrowser Print to Pdf

Question

My default printer is set to "nuance pdf" which saves files to pdf. I have console application that uses webBrowser.Print(). This command by-passes print pop up and brings up "Save As" page:

I want to pro-grammatically enter filename and save the file, without seeing this pop up. How do I achieve this? Any suggestions/pointers?

This is the code which I took from: C# : "How to use WebBrowser and print the html to the console. "

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            PrintHelpPage();
            Console.ReadKey();
        }

        public static void PrintHelpPage()
        {
            var th = new Thread(() => {
                var br = new WebBrowser();
                br.DocumentCompleted += PrintDocument;
                br.Navigate("http://google.com");
                Application.Run();
            });
            th.SetApartmentState(ApartmentState.STA);
            th.Start();
        }
    public static void PrintDocument(object sender,
        WebBrowserDocumentCompletedEventArgs e)
    {
        var browser = sender as WebBrowser;
        // Print the document now that it is fully loaded.
        browser.Print();

        // Dispose the WebBrowser now that the task is complete. 
        browser.Dispose();
    }
}

}
