How to print current page with webBrowser control to pdf?

Question

Programming

Hello! I want to print the current page from webBrowser to pdf
In Windows 10 there is “Microsoft Print to PDF”
Standard examples, when graphics are sent to the printer, work .... but how to send the current page of the webBrowser control to print? And without dialog boxes, since I need to programmatically save different pages.

private void button4_Click(object sender, EventArgs e)
        {


            // generate a file name as the current date/time in unix timestamp format
            string file = (string)(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1))).TotalSeconds.ToString();

            // the directory to store the output.
            string directory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

            // initialize PrintDocument object
            PrintDocument doc = new PrintDocument();

            doc.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
            

            doc.PrinterSettings.PrinterName = "Microsoft Print to PDF";
            // tell the object this document will print to file
            doc.PrinterSettings.PrintToFile = true;
            doc.PrinterSettings.PrintFileName = Path.Combine(directory, file + ".pdf");


            doc.Print();

            //webBrowser1.Print();


        }


        private void pd_PrintPage(object o, PrintPageEventArgs e)
        {
            webBrowser1.Navigate("https://stackoverflow.com/questions/40812996/programmatically-provide-a-filepath-as-input-file-for-microsoft-print-to-pdf-p");
        }
