Query: In concept, a great feature to add

The 460 is a great little printer, I bring it on business trips all the time, and people are always excited to see it (to print boarding passes, contracts, etc.)I was interested in going completely wireless using the battery and this BT card, but it is SLOW. It's directly next to my laptop right now and it took about 5 minutes to print a page that took no more than 20 seconds over USB. The file was not that large either.It is quicker to fly back home, pick up a USB cable, fly back, and use that cable than it is to print off a few documents over Bluetooth using this card.But, in concept it would have been a great feature to add to an otherwise amazing and functional portable printer. (Now, if this printer could scan and fax over VoIP/IP as well, that would be orgasmic!)
