The best printers & scanners to use on the road. Not for car use, but to use at a Starbucks/Panera

Looks like we may have to print / scan while on the road. Does anyone take portable Printer/Scanner on the road for use in Starbucks/Panera locations? Not talking about the Trunk conversions.

I find it easier to plug the printer up outside of a grocery store… park close enough or use an extension cord. You don’t need a socket for the scanner though.

Thanks. What equipment do you use?
