c# - 通过 Zebra 打印机 RZ400 验证编码标签

Question

下面是一个通过串口发送 ZPL 命令的 C# 函数。ZPL 命令以 ~RVE 开头（告诉打印机发送 RFID 编码成功或失败结果）。

如何在我的代码上下文中接收编码结果并检查编码过程是否成功？

    private void Print()
    {
        // Command to be sent to the printer
        string command = "~RVE^XA^RFw,H^FD033B2E3C9FD0803CE8000001^FS ^XZ";

        // Create a buffer with the command
        Byte[] buffer = new byte[command.Length];
        buffer = System.Text.Encoding.ASCII.GetBytes(command);
        // Use the CreateFile external func to connect to the LPT1 port
        SafeFileHandle printer = CreateFile("LPT1:", FileAccess.ReadWrite,
        0, IntPtr.Zero, FileMode.Open, 0, IntPtr.Zero);
        // Aqui verifico se a impressora é válida
        if (printer.IsInvalid == true)
        {
            return;
        }

        // Open the filestream to the lpt1 port and send the command
        FileStream lpt1 = new FileStream(printer, FileAccess.ReadWrite);

        Byte[] ResultBuffer = new byte[255];
        lpt1.Write(buffer, 0, buffer.Length);

        // Close the FileStream connection
        lpt1.Close();

    }
