DO NOT BUY AN HP PRINTER! This junky printer has been a thorn in my side since we bought it. Half the time it says the printer is offline when it clearly isn't. So they tell you to power cycle it, then for 15 minutes(I'm not exaggerating) it buzzes and clacks. As for the HP Smart app, it does not support double sided scanning. Even if your printer can do double sided scanning, for some reason the HP Smart app doesn't support it(?????). It even says so on their support website that this is true.
