<tr>

        <asp:Button ID="btnprnt" Text="Print" runat="server" 

            Width="86px" onclick="btnprnt_Click1" /></td></tr>

Step2: Create One button(btnprnt_Click)

print.aspx.cs

         Button1:            

protected void btnprnt_Click1(object sender, EventArgs e)

        {

            string htmlcode = "";

            

            htmlcode += "<table width=97% class='mylabel' cellpadding=10 align=center>";

            htmlcode += "<tr><td colspan=2><hr></tr>";

            htmlcode += "<tr><td align=right>Name:</td><td> " + txtnam.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>Phone Number:</td><td>"+txtph.Text+"</td></tr>";

            htmlcode += "<tr><td align=right>Date:</td><td>" + txtdat.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>Time:</td><td>" + txttime.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>No.of passengers:</td><td>" + Txtpass.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>language:</td><td>" + Txtlangue.Text + " </td></tr>";

            htmlcode += "<tr><td align=right>:Vehicle:</td><td>" + Dplist.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>Picup point:</td><td>" + Txtpic.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>pickup landmark:</td><td>" + Txtland.Text + "</td></tr>";

            htmlcode += "<tr><td align=right>Drop point:</td><td>" + Txtpoint.Text + "</td></tr>";

            htmlcode += "</table>";

            Session["htmlcodetoprint"] = htmlcode;

            Response.Write("<script language='javascript'>window.open('print.aspx','prn','toolbar=no,menubar=no,scrollbars=yes,location=no');</script>");

        }

Step3: create one page write in that"Print.aspx"

 protected void Page_Load(object sender, EventArgs e)

        {

            if (Page.IsPostBack == false)

            {

                string htmlcode = Convert.ToString(Session["htmlcodetoprint"]);

                Session["htmlcodetoprint"] = null;

                Response.Write(htmlcode);

                Response.Write("<script language='javascript'>window.print();</script>");

            }
