Stylus Color 760 print greek characters in DOS

Hi all,
I have the following issue: I use a DOS program that needs to print Greek alphabet characters to an Epson Stylus Color 760 printer. It's connected via parallel port and from what I've looked around I somehow need to send an ESC/P command to the printer and tell him to use the Greek character set (pc437 greek). I can't find anyone that shows how to properly syntax this command and how to send it. The following sites have some info on ESC/P but I need to know how to properly syntax it and how I call that specific greek character chart.

If it's of any help, you can look in the Epson ESC/P Reference Manual (saved from Epson's support site)

Any tips would be welcome! Thanks
