Question

    I have a Zebra ?MZ - 320 thermal printer.

    I? print with?my ?C# .net?CF? application and a WM5 device using bluetooth and serial port.

    I use the following code:

    ?
    Code Snippet

    ?

    using

    ?

    System.IO.Ports;

    ?

    SerialPort comPort1 = new SerialPort("COM8", 57600, Parity.None, 8, StopBits.One);

    comPort1.Open();

    ?

    StringBuilder DataString = new StringBuilder();

    DataString.Append(

    "! 0 200 200 240 1\r\n");

    DataString.Append(

    "LABEL\r\n");

    DataString.Append(

    "T ARI10PT.CPF 0 130 90 Καλημ?ρα\r\n");? // Printing ????? instead of Καλημ?ρα (Greek characters)

    DataString.Append("T 0 0 250 100 Goodmorning\r\n");???? // WORKS FINE

    DataString.Append(

    "FORM\r\n");

    DataString.Append(

    "PRINT");

    comPort1.WriteLine(DataString.ToString());

    comPort1.Close();

    ?

    ?

    ?

    ?

    I have created with Zebra Label Vista a font (Arial,Regular,size 10,script Greek,character range 32-255)

    and save it as ARI10PT.CPF.

    I then sent it to the printer.

    When I print from my desktop computer and Label Vista everything is fine.

    When I run the code from my device it prints ???? as many as the length of the string? and in size 10.

    Does anybody knows why the printer understands the length and size of created font,but not the greek character set.

    I repeat from my desktop computer everything works fine.

    ?

    Thanks in advance

    Sorry for my english.

? Hi,

? I had the same problem with -hebrew- fonts.
?
? and i solve it by convert the string to array of bytes.

?
? try this :

SerialPort comPort1 = new SerialPort("COM2", 57600, Parity.None, 8, StopBits.One);

comPort1.Open();

//here replace the hebrew text with greek/XXXX text
string sToPrint=Reverse("????? ") ;??

?
sToPrint=sToPrint+ "\r\n";

//here replace the Encoding "windows-1255" to greek/xxxx encoding
byte []arrByte1255= Encoding.GetEncoding("windows-1255").GetBytes(sToPrint);

comPort1.Write(arrByte1255,0,arrByte1255.Length );

comPort1.Close();
