Wireless printer, how many Dongles do I need???

http://www.newegg.com/Product/Prod [...] 6833242001
USB 2.0 Micro Bluetooth Dongle, using this Dongle as an example if I needed 2 Dongles to make a wireless printer work.


My HP PhotoSmart C5580 All-in-one Printer came with ONE bluetooth dongle. If I connect the dongle to the computer OR the printer neither can communicate with each other.

Am I required to have 2 bluetooth dongles in order to have the ability to use wireless printing?

ALSO, If I only need ONE Bluetooth Dongle for wireless printing do I connect it to the Printer or the Computer to make it work?
I've tried both already.

It's a few simple questions that even HP technical support couldn't or wouldn't answer.

Please help me, Please...

thanks
