Are stickers normally waterproof?

How do you make a machine that prints waterproof thermal stickers?

• I want to make a machine that can print waterproof thermal stickers about 12mm wide. I have Arduino Uno and Arduino Leonardo. And I want to use Arudino to control a thermal printer to printer waterproof label to stick on my own bottle, etc. I can buy Brother Laminated Black On White Tape 2Pack on Amazon. But I wonder that is there any part for thermal printer can print this type of tape and can be controlled by Arduino?

• Answer:

  As you have perhaps surmised the waterproof nature of the label is in the label materials (adhesive, media, and top covering). The p-touch printers are fairly inexpensive.  The print head is controlled to print letters and symbols of varying size and font.  There is likely not a convenient port to access the internal electronics but if you are building your own controller it seems you might be able to work out the electronics to bypass the p-touch internals and use the device as a printer.  Alternatively, the user group for Arudino may have some experience advice.
