That looks like a Victoria Arduino machine from Nuova Simonelli; I don't know a lot about how they operate because I've never worked on one, but it's a volumetric machine, and each of those buttons save one should be programmed for a dosed shot; one will be "manual" and pull shots until you press it again.
