I am developing a web-application (.net, c#) that needs to print png files using Zebra ZT410 printer. I am trying to use code from zebra examples (connect to printer with TCP/IP, port 9100 and print a sample text) - Zebra Technologies - Send ZPL Commands via TCP/IP in C#
I don't get any errors, but nothing is printing. I tried port 6101 too, no luck.
Any suggestions why it is not working?
 
            string ZPLString =
             "^XA" +
             "^FO50,50" +
             "^A0N50,50" +
             "^FDHello, World!^FS" +
             "^XZ";
 
 
            try
            {
                // Open connection
                System.Net.Sockets.TcpClient client = new System.Net.Sockets.TcpClient();
                client.Connect(ipAddress, port);
 
 
                // Write ZPL String to connection
                System.IO.StreamWriter writer =
                new System.IO.StreamWriter(client.GetStream());
                writer.Write(ZPLString);
                writer.Flush();
 
 
                // Close Connection
                writer.Close();
                client.Close();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
            }
            Console.Read();
