This papercraft model has plenty of parts, but most of them are white, so it won't use a lot of ink (you don't have to use any coloured ink at all ;o)
The legs are optional; the early LEGO Ghosts used a 1x2 brick and plate to make it appear as if they were floating.
For a real ghostly effect, you can print the Ghost shroud on glow-in-the-dark / Nachtleuchtpapier, but that's optional as well.
