I cannot get my IPAD to connect to my printer using Blutooth. I have an HP Photosmart D7160 printer that has Bluetooth. I bought a BT adaptor (HP BT500), plugged it into the printer, kept the defaults, cranked up BT on the IPAD, nothing. Called HP and they said I needed the BT450 printer adaptor. Bought one of those plugged it in the printer and this time the adaptor went searching (blinking light on adaptor) but still no connectivity. I have been through all the settings numerous times. I can't attempt to "pair" the devices because IPAD just sits there cranking in search mode. Help anyone?
