How do you change the ink for a thermal wax printer? -

I am doing a school project and I have looked all over the net. Help Me!

I have seen Tektronix printers like that and you don t replace the wax, you just add it What brand and model is your printer?

I thought that thermal printers used special paper that didn t require ink. I have never heard of a quot;thermal wax printerquot;. I have heard of a quot;thermal fax printerquot;. Okay, I looked it up. The quot;inkquot; comes on a roll of what appears to be carbon paper. When the roll is empty, you just have to buy another one.
