I thought portable printers started to die when portable internet started taking off...

I have one for mobile ambulance command, as my vehicle isn't large enough to run a 240v generator, and sometimes I need to generate documents on site such as maps or checklists to give to crews then going away from the vehicles.

I would imagine some sales reps needing to produce A4 documents on headed paper etc for a customer to sign there and then may also do this, again their Mondeo's can only carry so much...
