Bluetooth printing from iPad? The company I work for had people out in the field doing data entry on their iPads.  We would like them to be able to print from the iPad to a bluetooth printer in their car, but I'm not sure if this can be done.  We tried using the HP Officejet 100 Mobile Printer, but while we can connect using bluetooth we have been unable to print.  

Has anyone done this?  If so, can you point me in the right direction?
@Jason's link to SO is correct - the out-of-the-box iPad will not support Bluetooth printing. However, there are receipt printers like Blue Bamboo or the Star Mobile printer, but these solutions might not be what you're looking for.

There are iBluetooth apps now in the iOS App Store - it's possible that the vendor no longer supports the Cydia version.

Another possible solution is an app like PrintCentral, which allows for printing wirelessly over 3G and WiFi.
