>>>2. Must have blue tooth connectivity.

>>I've never heard of a dot matrix printer that has native Bluetooth connectivity. If it has to be dot matrix maybe you could use a Bluetooth to parallel adapter e.g. http://mobileoffice.about.com/od/mobileprinters/tp/bluetoothprint.htm

>>As for battery power, is there any chance you could run the printer from the van's power via an inverter e.g. plugged into a cigarette lighter socket? That would widen your list of candidate printers.
