Thermal Printer POS-5890C with arduino

Hello, I want to print things with thermal printer POS-5890C. Can someone guide me to do this? I have a Mega ADK via which I can connect it with the printer


First of all you need the data sheet of your printer, telling how to connect it and how to send data to it. Eventually you should look for another printer, coming with a data sheet and Arduino library and example code.
