How to check if the Zebra printer prints correctly using ZPL and C # (or error detection capability)?

Question

Problem

Is there a simple ZPL code or a way to get an error message from a Zebra printer to determine if these labels were not printed successfully or that there was some kind of error?

Progress

Here is a nice feature that I created to send a printer job to a zebra printer:

public static void SendToPrinter(string zplString, string ipAddress = "127.0.0.1", int port = 1337)
        {
            // Open connection
            TcpClient tcpClient = new TcpClient();
            tcpClient.Connect(ipAddress, port);

            // Write ZPL String to connection
            using (System.IO.StreamWriter writer = new System.IO.StreamWriter(tcpClient.GetStream()))
            {
                writer.Write(zplString);
                writer.Flush();
                writer.Close();
            }
            // Close Connection
            tcpClient.Close();
        }

ZplString has a lot of magic, but it’s mostly ZPL code that we all love. The problem with my approach is that it seems to be more like a one-way printer ticket. A lot of work went into the above, and I hope that we can somehow change it to listen to the answer, if I somehow had the appropriate ZPL code to listen to the answer?
