I'm facing the same problem. Did you already manage anything on this subject?

Ax Perez Parra Castro, this is how I did it:

-get the RawPrinterHelper class from here http://support.microsoft.com/kb/322091

-my printer (zebra 2030) doesn't support ZPL, so as far as I know the only way is to send unicode to it

-I made a list of characters I need e.g.

string enq = Convert.ToChar(5).ToString();
string esc = Convert.ToChar(27).ToString();
string nul = Convert.ToChar(0).ToString();
string rs = Convert.ToChar(30).ToString();
string lf = Convert.ToChar(10).ToString();
string cr = Convert.ToChar(13).ToString();

(get those int values from en.wikipedia.org/wiki/ASCII)

-compose the command - e.g. sb.Append(esc + enq + Convert.ToChar(7).ToString()); (from the printer manual, the command < ESC>< ENQ><7> should get the firmware version)

-send the command RawPrinterHelper.SendStringToPrinter(printerName, sb.ToString()); (printerName in my case is "Zebra TTP 2030")
