I think your method is rather complex and if you use this .NET PDF component: http://www.e-iceblue.com/Introduce/pdf-for-net-introduce.html , it can easily convert webpage to PDF , only three key steps:

using Spire.Pdf;

namespace htmltopdf
{
class Program
{
[STAThread]
static void Main(string[] args)
{
//Create a pdf document.
PdfDocument doc = new PdfDocument();
String url = "http://www.london2012.com/news/articles/paralympic-torch-relay-route-revealed-1258473.html";
doc.LoadFromHTML(url, false, true, true);
//Save pdf file.
doc.SaveToFile("sample.pdf");
doc.Close();
//Launching the Pdf file.
System.Diagnostics.Process.Start("sample.pdf");
}
}
}


Never give up! Smile to the world!
