There are several ways to connect to a BT printer; one is a "hard cable replacement profile" which in essence just replaces the printer cable with Bluetooth, the other is the basic printing profile. The major difference is that one needs the same drivers as on the PC (printer driver) while the other (BPP) has a printing protocol integrated meaning the PDA or phone can access any printer that supports BPP. I'm pretty sure that most HP printers support both, my photosmart will accept prints in BPP as well as with the regular printer driver connecting to it.
