Mobile Printers

Can anyone give me assistance for a mobile printer?

I'm looking for a thermal, mobile printer which can be used to print a 5x7" invoice from paper rolls. Perhaps a USB interface, Windows Vista compatible and has a cigarette lighter DC pwr-supply. My internet searches for this had terrible results, new to these types of printers. Can anyone help?

1. I'd go to the source and HP.com get customer service find make and Model #s then go to Ebay or another place for a decent price.
2. I am unaware of any mobile printers that print from paper rolls. I haven't heard of any that do that. Here are the only mobile printers I am aware of; HP H470 (entry level mobile printer, does not include cigarette lighter power supply, although those can be found elsewhere). $250 HP H470b (same as H470, but comes with a battery that will print 480 pages per charge). $300 HP H470wbt (same as H470b, but also has wireless and bluetooth). $350 The Prices on these HP mobile printers are regular retail. HP is currently running a sale on these printers, so the prices on HP's website at the time of my answer were about 10% cheaper than the prices that I listed. Canon ip100 (An entry level mobile printer, similar to the HP H470). $250 These will all print on 5x7 paper, but not from paper rolls.
