Beginner question regarding thermal printer to Arduino

Projects Networking, Protocols, and Devices

Hi experts, I found an interesting site(http://tronixstuff.wordpress.com/2011/07/08/tutorial-arduino-and-a-thermal-printer/) to control a thermal printer with arduino..but I'm not really sure how to connect the printer to the arduino. Do I need to use Rs232 to ttl converter(hope I'm correct) or I can directly connect it to arduino? Please see attached file(picture of my thermal printer).

Thanks in advance,
mbox

I thinks its made in China, and I don't have any idea of its Brand/model. I got this from a friend without a box and manual.

Yes, you do.
