        function print() {
            window.print();

In code behind:

    protected void Page_Load(object sender, EventArgs e)
    {
      ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "script", "print()", true);

It should be

ScriptManager.RegisterStartupScript(this,this.GetType(), "Javascript", "javascript:print();", true);

I created a sample and code flow reaches the javascript function on page load event.

C#

protected void Page_Load(object sender, EventArgs e)
       {
           ClientScript.RegisterStartupScript(GetType(), "Javascript", "javascript:print(); ", true);
       }

<html xmlns="http://www.w3.org/1999/xhtml">

    <title></title>

    <script lang="javascript" type="text/javascript">

        function print() {
            // window.print();
            alert('hello');
        }
    </script>
