Zebra Printer Russian Character


I have a zebra zt410 printer. I've found a class to print a barcode with it.

RawPrinterHelper.cs

public class RawPrinterHelper

    }

I'm sending data to printer like below:

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());

English characters print normally, but Russian characters don't. I've changed this line in RawPrinterHelper.cs

pBytes = Marshal.StringToCoTaskMemAnsi(szString);

to

pBytes = Marshal.StringToCoTaskMemUni(szString);

but no effect.

Any help?

Regards.


Solution

  • this link has given me an idea: Unicode characters on ZPL printer

    I haven't done it with sending string, but I'm creating a uft-8 file before every printing job and sending this file to printer. It's solved my problem.

    If someone needs:

    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);
