How to print direct to zebra printer without setting it as a default printer using C#?

Question

I'm new to programming.

I want to print direct to the Zebra Printer without setting the printer as a DEFAULT because I'm using one computer that is connected to many printers, and also bear in mind i'm getting the records/DATA from a web browser when PRINT Button is clicked

How can i achieve this ? Thanks in advance.

The following code works fine if the printer is set to DEFAULTS

<%@ Page Language="C#" AutoEventWireup="true"%>
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ Import Namespace="System.IO" %>

    System.Web.Script.Serialization.JavaScriptSerializer jsoner = new System.Web.Script.Serialization.JavaScriptSerializer();

    string UtiWayBillNumber =Request.QueryString["UtiWayBillNumber"];
    string labelSerials = Request.QueryString["labelSerials"] ?? null; 
    string[] serialNumbers = labelSerials.Split('$');


    using (SqlConnection dbConnection = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["HestoProductionControl"].ConnectionString))
    {
        dbConnection.Open();

        SqlCommand cmd = dbConnection.CreateCommand();
        cmd.CommandType = System.Data.CommandType.StoredProcedure;
        cmd.CommandText = "GM_GetShipmentDetailInformation";
        cmd.Parameters.AddWithValue("@utiWaybillNumber", UtiWayBillNumber);
        SqlDataReader reader = cmd.ExecuteReader();
        System.Collections.Generic.List<object> labelList = new List<object>();

        string appPath = Request.PhysicalApplicationPath;
        string IPAddress = HttpContext.Current.Request.UserHostAddress;

            StringBuilder fileContents = new StringBuilder();

        while (reader.Read())
            {

             if (labelSerials.StartsWith(" "))
                {

                        quantity = quantity.Remove(2,7);


                        fileContents.Append(reader["HestoBarcodeSerial"]);

Is the printer listed in the list of printers on your system? If so, you can use

PrintDocument pd = new PrintDocument();
pd.PrinterSettings.PrinterName = "Zebra Printer";

// Do stuff formatting your document, like drawing strings and images (possibly a zebra?)

if(pd.PrinterSettings.IsValid) pd.Print();
else MessageBox.Show("Printer is invalid.");

Note: I got this off of this thread on another forum, but I'm using a similar method to print to a specific printer when I don't know if it's the default printer.

I just noticed that you're probably using a web site. The above method is only usable if you were to use it server side in order to select the default printer.

I don't know if this can be done client side but I doubt it. It would give your website access to your client's computer which is a huge security breach. I think you'd have to show a print dialog in which users can select the printer to use.
