If you're speaking of the thermal printing process, no.
The thermal part of the process works a bit like a laser printer.
The "ink" is a roll of thin black plastic. It is thermally "welded" to the plastic tag or label.
If you look at the "ink" roll after it does a transfer you will see all of the plastic "ink" missing from the roll.

I believe you are thinking of the old thermal paper used in 80s TI calculator printers.

Edit to add a few details.

Nice to know. Learned something new. Thanks. Are you taking orders? 😁

Not sure, but does the label turn black when the engine warms up?

Not sure whom your asking.

This process is called "thermal transfer." Easily confused with "thermal" printing which uses heat to change the color of the paper. Thermal transfer is much more durable and is not subject to fading or darkening due to heat.
