It's more complicated than that. The Bluetooth "driver" isn't really a driver, it's a set of apps that allows the computer to use Bluetooth for various functions, like speech, file transfer, etc. The Microsoft BT stack (that's what software like that is called - a stack) is about as useful as a piece of water in chopping down a tree. (Yes, I said "a piece of water" - that's more real than Microsoft's BT stack.) There are a few good ones (I like the one Toshiba put out), but you only get them bundled with devices and they usually only provide functions that device would use. (IOW, one bundled with a headphone wouldn't do printing.)
It's much easier in the other direction. There are Android apps that allow you to do Bluetooth eveything, from headsets to printing to ... well, just about any device that uses Bluetooth. If what you're trying to do is transfer files between the phone and the computer, try AirDroid or Wifi File Transfer. Both of them are pretty intuitive and simple to set up. If you want to print from your phone, use Cloud Print (the one by Paulo Fernandes). You set your printer to "be on" the cloud (the instructions are in the app - it's trivial) and you can print from the phone. (I've tried a few of them - this one worked on the first try. Some of them were a waste of half an hour.)
