斑马打印机俄文字符

Question

我有一台 zebra zt410 打印机。我找到了 class 可以用它打印条形码。

RawPrinterHelper.cs

public class RawPrinterHelper
{
    // Structure and API declarions:
    [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);

    // SendBytesToPrinter()
    // When the function is given a printer name and an unmanaged array
    // of bytes, the function sends those bytes to the print queue.
    // Returns true on success, false on failure.
    public static bool SendBytesToPrinter(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 you did not succeed, GetLastError may give more information
        // about why not.
        if (bSuccess == false)
        {
            dwError = Marshal.GetLastWin32Error();
        }
        return bSuccess;
    }

    {
        // Open the file.
        FileStream fs = new FileStream(szFileName, FileMode.Open);
        // Create a BinaryReader on the file.
        BinaryReader br = new BinaryReader(fs);
        // Dim an array of bytes big enough to hold the file's contents.
        Byte[] bytes = new Byte[fs.Length];
        bool bSuccess = false;
        // Your unmanaged pointer.
        IntPtr pUnmanagedBytes = new IntPtr(0);
        int nLength;

        nLength = Convert.ToInt32(fs.Length);
        // Read the contents of the file into the array.
        bytes = br.ReadBytes(nLength);
        // Allocate some unmanaged memory for those bytes.
        pUnmanagedBytes = Marshal.AllocCoTaskMem(nLength);
        // Copy the managed byte array into the unmanaged array.
        Marshal.Copy(bytes, 0, pUnmanagedBytes, nLength);
        // Send the unmanaged bytes to the printer.
        bSuccess = SendBytesToPrinter(szPrinterName, pUnmanagedBytes, nLength);
        // Free the unmanaged memory that you allocated earlier.
        Marshal.FreeCoTaskMem(pUnmanagedBytes);
        return bSuccess;
    }

    /// <summary>
    /// 
    /// </summary>
    /// <param name="szPrinterName"></param>
    /// <param name="szString"></param>
    /// <returns></returns>
    public static bool SendStringToPrinter(string szPrinterName, string szString)
    {
        IntPtr pBytes;
        Int32 dwCount;
        // How many characters are in the string?
        dwCount = szString.Length;
        // Assume that the printer is expecting ANSI text, and then convert
        // the string to ANSI text.
        pBytes = Marshal.StringToCoTaskMemAnsi(szString);

        // Send the converted ANSI string to the printer.
        SendBytesToPrinter(szPrinterName, pBytes, dwCount);
        Marshal.FreeCoTaskMem(pBytes);
        return true;
    }

我正在向打印机发送数据，如下所示：

StringBuilder strBldr = new StringBuilder();
strBldr.AppendLine("^XA");
strBldr.AppendLine("^FO40,100");
strBldr.AppendLine("^AQ,50,30");

strBldr.AppendLine(string.Format(CultureInfo.InvariantCulture, "^FO220,50^A0,30,30^FD{0}^FS", m.No));

strBldr.AppendLine(string.Format(CultureInfo.GetCultureInfoByIetfLanguageTag("en-EN"), "^FO220,90^A0,30,30^FD{0}^FS", m.DescriptionENG));

strBldr.AppendLine(string.Format(CultureInfo.GetCultureInfoByIetfLanguageTag("ru-RU"), "^FO220,130^A0,30,30^FD{0}^FS", m.DescriptionRUS));

strBldr.AppendLine("^FO100,300^BY2");

strBldr.AppendLine("^BCN,60,Y,N,Y,N");
strBldr.AppendLine(string.Format(CultureInfo.InvariantCulture, "^FD{0}^FS", m.No));
strBldr.AppendLine("^XZ");

RawPrinterHelper.SendStringToPrinter("ZDesigner ZT410-203dpi ZPL", strBldr.ToString());

英文字符打印正常，但俄文字符打印不正常。我在 RawPrinterHelper.cs

中更改了这一行

pBytes = Marshal.StringToCoTaskMemAnsi(szString);

到

pBytes = Marshal.StringToCoTaskMemUni(szString);

但没有效果。

有什么帮助吗？

此致。

这个link给了我一个想法：Unicode characters on ZPL printer

我还没有通过发送字符串完成它，但我在每次打印作业之前创建一个 uft-8 文件并将该文件发送到打印机。解决了我的问题。

如果有人需要：

StreamWriter sw11 = new StreamWriter(fileName, false, Encoding.UTF8);
sw11.WriteLine("^XA");
sw11.WriteLine("^FO40,100");
sw11.WriteLine("^AQ,50,30");
sw11.WriteLine(string.Format(CultureInfo.InvariantCulture, "^FO200,50^A0,40,40^FD{0}^FS", m.No));
sw11.WriteLine(string.Format(CultureInfo.GetCultureInfo("tr-TR"), "^FO200,100^A0,30,25^FD{0}^FS", m.DescriptionTR));
sw11.WriteLine(string.Format(CultureInfo.GetCultureInfo("en-US"), "^FO200,135^A0,30,25^FD{0}^FS", m.DescriptionENG));
sw11.WriteLine(string.Format(CultureInfo.GetCultureInfo("ru-RU"), "^FO200,170^A0,30,25^FD{0}^FS", m.DescriptionRUS));
sw11.WriteLine(string.Format(CultureInfo.GetCultureInfo("en-US"), "^FO200,205^A0,30,25^FD{0}^FS", m.Model));
sw11.WriteLine("^FO100,300^BY2");
sw11.WriteLine("^BCN,60,Y,N,Y,N");
sw11.WriteLine(string.Format(CultureInfo.InvariantCulture, "^FD{0}^FS", m.No));
sw11.WriteLine("^XZ");
sw11.Close();
RawPrinterHelper.SendFileToPrinter(printerName, fileName);
