Money maker illusion

Super Fun effect for the table or a birthday.

You tell your audience that you have received a special device to print your own money.
All you need is a banknote.

Borrow a 10-euro banknote and lay it on the printer. You go there with the roller over and apparently nothing happens, except that there are now some ink on the roller. You give the note back and says the roller now the ink has taken ...
Then pick up a white piece of paper and put it in your printer.
Again you go there with the roller over it, but ... very visibly changed the white paper in a banknote of 10 euros !!!
Get the banknote out and put it in your pocket.

Would someone really taking the mickey ... often tell spectators; do it again? Ask the banknote to borrow again and say that you will try it again. Put the ballot to the printer and ... this has now changed to a white wrappers.
Say something, from oops ... the battery is exhausted. Gives the white paper to your audience and you earn another 10 Euros.

You can also change predictions, or alter a 10 euros in 50, or .... you name it.

This version is, unlike some chinese providers of high quality!
