You should be more detailed what you want to do: there are (cheap) thermal pos printers and you find many messages how to print to them. Normaly this type of printer is programmable with Esc/p, a printer language originaly definded by epson.
Than there exists high level thermal business label printer, many of them use their own printing language. For serial or usb printing are many examples, how to transmit date to them.
