Are there any Bluetooth experts out there?

I’m working on a project where the employee would be in a warehouse, carrying an Android or iPad tablet, a bluetooth barcode reader (to read the item barcodes), and a small bluetooth printer. In that way, the person could, in one action: (a) scan and grab the item, (b) have the tablet upload the revised inventory status, and© print out a packing/routing slip for the item.

Does Bluetooth support more than one active connection at a time?

[I know that the Bluetooth standard says that a device should, to be compliant, support up to 7 active connections. But… not all standards are implemented fully.]
