Yeah, well some modern printers even have Bluetooth built into them.
But it is better to use a Wifi print server imho, although it does come at a cost as with everything.
When bluetooth was originally conceieved, the idea was that by 2005, every printer and other peripheral would be using it, we would be in a truely wireless world... but thanks to the unexpected high cost of bluetooth chips (licensing) as well as the lacklustre below par performance of the technology, it never really hit on.
Shame really.
