How to get Network Printers in ASP.NET

I need to show printers installed in network. I used the below code to show printers but locally it shows network printers, but when hosted in IIS it doesn't show network printer.(shows only local printers).

code -1:

     ApplicationPrinter printer = new ApplicationPrinter();
     ddlPrinters.DataSource = printer.InstalledPrinters();
     ddlPrinters.DataBind();
     ddlPrinters.SelectedItem.Text = printer.DefaultZebraPrinter();

code -2:

    ddlPrinters.Items.Clear();

        try
        {
            // Use the ObjectQuery to get the list of configured printers
            ObjectQuery oquery =
                new ObjectQuery("SELECT * FROM Win32_Printer");

            ManagementObjectSearcher mosearcher =
                new ManagementObjectSearcher(oquery);

            ManagementObjectCollection moc = mosearcher.Get();

            foreach (ManagementObject mo in moc)
            {
                PropertyDataCollection pdc = mo.Properties;
                foreach (PropertyData pd in pdc)
                {
                    if ((bool)mo["Network"])
                    {
                        ddlPrinters.Items.Add(mo["Name"].ToString());
                        break;
                    }

                }
            }
        }
        catch (Management开发者_JAVA百科Exception ex)
        {
            string msgDesc = string.Empty;
            string script = string.Empty;
            msgDesc = ex.Message;
            script = "<script language=\"javascript\">alert('" + msgDesc + "'); </script>";
            ScriptManager.RegisterStartupScript(this.Page, typeof(Page), "UserMessage", script, false);
        }

Here if ((bool)mo["Network"]) is used to show only Network printers.

Is there any way to get network printers in ASP.NET?

Adding this line to the section of the web.config does the trick. The userid provided needs to have the network printers mapped.

<identity impersonate="true" userName="domain\user" password="password" />

Have you tried installing the network printer on the workstation first, and then do a win32_printer query?

P.s. you can install it by \\printername
