We are currently supporting Piezography2 ink sets in the P400 printer. Piezography Pro software is optional. It allows you to make your own media profiles and to do other cool things. We already supply a ton of free Piezography media profiles. And we highly recommend that you PiezoFlush your printer prior to installing Piezography inks in order to flush out the color pigment stain as well as to clean the ink stems so that they do not put unwanted color pigment stain into your Piezography filled ink carts!
