I get plenty of hits for a USB powered portable scanner but not a printer/scanner. My guess is you'll need one of each but that's not so bad. Also, I suspect portable laser printers you can use within an automobile will be scarce if they even exist. This will be because laser printers need much more current than inkjets. Portable inkjets are plentiful. Canon makes portable injet printers and portable scanners but I don't see dual capability in these. Try google.
