HP and Samsung are coming together to make a seamless print client between Samsung devices and HP printers. No need for an app. Just “print”. Sure beats all the proprietary apps out there BUT….this is still proprietary and thought built in, it only will work for HP printers (newer ones that that) . It would be nice if there was a standard that the print and mobile folks would follow instead.
