From BeamBerry Solutions:
BeamBerry is much more than a document viewer though. You can also print your documents directly from your BlackBerry to any Bluetooth enabled printer. Simply pair your BlackBerry device with the printer and print your documents. If your printer is not Bluetooth enabled, you can still print your documents to it by connecting a Bluetooth printer adapter to your printer that connects to the printers USB port. A key differentiator of our solution is that it allows you to easily and transparently print to over 1500 compatible printers from virtually any BlackBerry device, not just the latest and the most powerful BlackBerry. This version is the first release on CNET Download.com.
