    doc.Add(paragraph);

    doc.Add(pharse);

    doc.Add(chunk);
    doc.Close(); //Close document

Your button click is simply creating a document in memory, writing to it and closing it.

You need to output the document to the Response.Output stream.

This works for me:

protected void PrintButton_Click(object sender, EventArgs e)
{
    if (!Page.IsValid) return;
    Response.ContentType = "application/pdf";
    using (var document = new Document())
    {
        PdfWriter.GetInstance(document, Response.OutputStream);
        document.Open();
        document.Add(new Paragraph("Hello PDF!"));
        document.Close();
    }
}

The main thing that you were missing was the PdfWriter which writes the document to the Response.OutputStream
