Suppress about:blank in Print Output of WinForms WebBrowser

Question

I'm updating a WinForms application that uses System.Windows.Forms.WebBrowser to output some HTML content generated by the program. The solution works fine, except that about:blank is printed in the footer of each page.

Is it possible to suppress that output? Alternatively, is there a straightforward alternative for printing HTML from WinForms that does not have that issue?

The client does not want to assume the presence of any third-party software such as Excel or even a PDF reader.

Answer 1

public void ClearBrowserPrintHeaderAndFooter()
{
    string path = "Software\\\\Microsoft\\\\Internet Explorer\\\\PageSetup";
    Microsoft.Win32.RegistryKey key = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(path, true);
    if (key == null) {
        key = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(path, true);
    }
    key.SetValue("header", "");
    key.SetValue("footer", "");
    key.Close();
}

Silly but it's the way.
