Bluetooth Printing...

I have an Alltel 8130 and my superintendent has an Alltel 8703e. We both have beamberry and are trying to print to a printer in the vehicle. I bought an Epson Stylus CX7450 and then evidently mistakenly bought an Hp BT450 bluetooth printer adapter. Evidently this only compatible with HP printers. So, I tried getting an EPoX bluetooth adapter as beamberry suggests. They're out of stock or is unavaialable everywhere I look. Help. Any suggestions?

Also, am I correct in my thinking that you cannot print with the USB wire from the blackberry to a printer?

THANKS!
