"No-Label" Label printer

Label printers are still used in almost every office all over the word. What if you could skip the label and print directly to the object? This should work with any surface where a permanent marker would work.
It programs just like any other label maker. Say you want to label the kid's pencil box. You type in "PENCILS" into the ETI No-Label Maker. Then you start rolling the coated rubber wheel along the surface of the box. The internal printer puts the ink to a film that wraps around the wheel. As you roll the ink gets transferred to your pencil box.
I think this is a great idea. Definitely the whole million dollars. It could be used in every industry. There is a refill option with the film and the ink. It takes a concept that everyone knows like label printing and reintroduces it to the world.
Till next time - keep inventing
