Hmmm... It doesn't appear that there is a Bluetooth scanner which is compatible with an Android device. They all seem to work via USB, or an adaptor. Here is a link to supported hardware for Android. Down at the bottom, there is a list of compatible scanners that you can use.
I use Dymo thermal printers for barcode labels. ( Get your labels from Discount Thermal Labels... Best price ever). I use the Dymo Twin Turbo (because it can house 2 label sizes, so I don't have to change rolls every other print). Dymo also makes a print server that will connect the printer to your network so you can print wirelessly. There are a ton of other print servers out there that will probably work, but I got the Dymo brand because of the reviews, and simplicity. With a network printer, you can get clever and host your barcode labels somewhere online, or on your device, and just email them to your printer. Depending on your setup and workflow, a print server might be unnecessary.
