For the demonstration I printed using a Coffee and printing medium mix. As the coffee isn't a liquid mixing it with the printing medium helps to turn it into a liquid that will easily be pushed through the mesh. The smell of coffee does linger on the paper for a while but it eventually disappears, if you wanted the smell of coffee to remain it would be worth experimenting with a stranger coffee and maybe creating a mix that has more coffee than printing medium.
