The only solution that I can think of is to convert the Greek Chars to
Hexadecimal.
Some more information that I have found and that could help you understand the
issue I am facing.
I have changed the document.jzebra.setEncoding("cp737");
This is supposed to be the right code page for Greek Language.
http://www.ascii-codes.com/cp737.html
The applet, recognized the new encoding and in the console.log it printed
INFO: Current applet charset encoding: x-IBM737
http://www.fileformat.info/info/charset/x-IBM737/list.htm
BUT, when I tried to print some Greek Hex chars from the table above, it just
display a questionmark ? in its place. Both in the console.log of java platform
and at the printer.
So my new question is why doesn't it print the Greek Hex chars?
For example: \xA0\xA1\xA2\x87 etc
Hope someone can help me on this.
Thank you!

Can you try this:
applet.setEncoding("UTF-8");
applet.append("\u0394"); // Unicode greek letter "Delta"
applet.append("\u03A3"); // Unicode greek letter "Sigma"
applet.append("\u03A9"); // Unicode greek letter "Omega"
applet.setEncoding("cp737"); // Convert string to x-IBM737 just before printing
applet.print();
For some reason with this approach, the file opens with a hex editor and
reflects the CP737 values. My guess would be that it's either a bug with
jzebra or java.
Switching back to cp737 may not be needed if your printer supports unicode.
As far as the output in the Java Console, don't trust that, since cp1252 on
Windows doesn't know how to display them.
I debugged this in Windows 8 by creating a Generic Text printer that printed to
FILE: and then opened the PRN output file with XVI32.exe hex editor.

Hello all, I am facing the same issue and you put me in the right direction
here, by setting encoding to cp737 just before printing. In my case I set cp737
to printer but not to applet, so I had to comment out line 1726 of
PrintApplet.java in method setEncoding(String charset) //this.charset =
Charset.forName(charset);
So when inside javascript I call qz.setEncoding("cp737"); it sets the
printer's character set but leaves applet's character set being the default
(UTF-8 in my system). Doing that, I call qz.append("ΔΣΩ\r\n"); and it prints
correctly.
I shall make more tests on this...
