I use an Anycom Bluetooth adapter to connect the laptop to my Epson printer in another room. Only problem is it doesn't seem to be fully bi-directional as I don't get the ink level feedback from the printer.
Unless it's a switch-pigs on my behalf!
Just for the heck of it, I tried using a wireless mouse, wireless router and Bluetooth printer all at the same time that the Vodafone Mobile Connect card was running - all on the same laptop.....
Much to my surprise, all worked fine! Even with another GSM phone connecting to a DECT next to the laptop!
