斑马标签打印机c# SDK

Question

我们刚刚从brother label打印机转移到了zebra，brother sdk的c#版看起来很不错，但它做了我想要做的事情。基本上，它为我提供了在设计器中创建标签并将引用名称附加到文本文件、条形码文件等的选项。然而，看着斑马，我似乎找不到一种方法来做到这一点。我不喜欢的事实是，你必须使用缺乏此功能的设计器来设计标签，或者在c#中100%地设计，这会阻止我们的设计师以后重新设计标签，也就是硬编码标签是行不通的。

我一直在寻找由新动力的热敏标签，但它的成本很高，为这个小东西。

有没有我错过的解决方案？大量的谷歌搜索，甚至试图弄清楚如何通过c#将现有的兄弟标签打印到斑马打印机上。这是可能的，因为p-touch可以做到这一点，但我也认为sdk缺乏这一功能，这使得它无论如何都是不可能的。

在查看了brother sdk的更多选项后，我注意到我可以获得bmp格式的标签，这可以方便地打印到斑马标签打印机上吗？

Answer 1

当我找到源链接时，我会添加它，但这是我现在打印到我们的斑马的方式：

[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
        public class DOCINFOA
        {
            [MarshalAs(UnmanagedType.LPStr)]
            public string pDocName;
            [MarshalAs(UnmanagedType.LPStr)]
            public string pOutputFile;
            [MarshalAs(UnmanagedType.LPStr)]
            public string pDataType;
        }
        [DllImport("winspool.Drv", EntryPoint = "OpenPrinterA", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool OpenPrinter([MarshalAs(UnmanagedType.LPStr)] string szPrinter, out IntPtr hPrinter, IntPtr pd);

        [DllImport("winspool.Drv", EntryPoint = "ClosePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool ClosePrinter(IntPtr hPrinter);

        [DllImport("winspool.Drv", EntryPoint = "StartDocPrinterA", SetLastError = true, CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool StartDocPrinter(IntPtr hPrinter, Int32 level, [In, MarshalAs(UnmanagedType.LPStruct)] DOCINFOA di);

        [DllImport("winspool.Drv", EntryPoint = "EndDocPrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool EndDocPrinter(IntPtr hPrinter);

        [DllImport("winspool.Drv", EntryPoint = "StartPagePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool StartPagePrinter(IntPtr hPrinter);

        [DllImport("winspool.Drv", EntryPoint = "EndPagePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool EndPagePrinter(IntPtr hPrinter);

        [DllImport("winspool.Drv", EntryPoint = "WritePrinter", SetLastError = true, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]
        public static extern bool WritePrinter(IntPtr hPrinter, IntPtr pBytes, Int32 dwCount, out Int32 dwWritten);


public static bool SendStringToPrinter(String printerName, String dataString)
        {
            int dwCount = (dataString.Length + 1) * Marshal.SystemMaxDBCSCharSize;

            // Assume that the printer is expecting ANSI text, and then convert
            // the string to ANSI text.
            IntPtr pBytes = Marshal.StringToCoTaskMemAnsi(dataString);
            // Send the converted ANSI string to the printer.
            SendPBytesToPrinter(printerName, pBytes, dwCount);
            Marshal.FreeCoTaskMem(pBytes);
            return true;
        }


        public static bool SendPBytesToPrinter(String szPrinterName, IntPtr pBytes, Int32 dwCount)
        {
            Int32 dwError = 0, dwWritten = 0;
            IntPtr hPrinter = new IntPtr(0);
            DOCINFOA di = new DOCINFOA();
            bool bSuccess = false; // Assume failure unless you specifically succeed.
            di.pDocName = "My C#.NET RAW Document";
            di.pDataType = "RAW";

            // Open the printer.
            if (OpenPrinter(szPrinterName.Normalize(), out hPrinter, IntPtr.Zero))
            {
                // Start a document.
                if (StartDocPrinter(hPrinter, 1, di))
                {
                    // Start a page.
                    if (StartPagePrinter(hPrinter))
                    {
                        // Write your bytes.
                        bSuccess = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);
                        EndPagePrinter(hPrinter);
                    }
                    EndDocPrinter(hPrinter);
                }
                ClosePrinter(hPrinter);
            }

            if (bSuccess == false)
            {
                dwError = Marshal.GetLastWin32Error();
                //TODO: log error code
            }
            return bSuccess;
        }

其中dataString是打印机解释的ZPL。

Answer 2

您可以将ZPL代码保存到一个简单的文本文件中，然后使用shell命令在LPT1上移动它。

如果您的斑马是通过网络连接的，最简单的方法/解决方法是使用"NET use lpt1：[ip]zebra /persistent:yes

您可以使用Zebra Designer通过“打印到文件功能”轻松地生成ZPL。
