so i moved to a different country and they have 220V...stupid me forgot the hp a616 portable printer was only specified up to 110 so needless to say i burned the adapter/charger that plugs into the walls. I can't get it fixed and i dont know where to buy a new adapter. BUT, on the back of the unit, right above where the adapter connects to is a usb port (B). Now, can i use that to provide power to the unit? Say a A to B usb cable? here's a link for reference http://www.superwarehouse.com/HP_Photosmart_A616_Printer/Q7112AABA/p/1488034 you can click on more images then check out the back panel of the unit. thanks in advance.
