IB4138,
Hola! Que tal? I must disagree with what you've written about inkjet printers. I've used injet printed boarding passes to depart UK airports thirty five times in the last twelve months alone and not once has the scanner refused to recognise what my printer had produced. Of course, if a passenger is idiotic enough to fold the A4 sheet a dozen times, then put it into his/her back pocket for good measure, well.... Hasta!
