The wax printer does what looks like printing. It is printing. You put that on, you warm it a little bit, the wax prints through, so it absorbs into the paper, and you end up with the device you want.
La impresora de cera hace algo parecido a imprimir. Es imprimir. La encienden, la calientan un poco. La cera se imprime de forma que se absorbe en el papel. Y terminan con el dispositivo que quieren.
