The idea of creating a printer with erasable ink is not new. Development of such a device began to engage in 15 years ago, but it turned out to be implemented only now. A peripheral device called Eco Printer prints text on paper using special inks that are erased by ultraviolet radiation.
As you know, industrial paper production has a negative impact on the environment. First, a person cuts down trees, and then throws out the used paper. A partial solution to the problem was the creation of invisible ink. However, using creased or damaged paper will not work again. The printer also does not allow to erase the inscriptions made with traditional ink and pencil.
