Which printer for location prints?
The Pro-10 and Pro-100 are large, heavy, bulky printers. I don't think they'll be very happy being moved around.
This isn't something I've done, but I've thought about using a DC-to-AC converter (inverter?) to power a CLI-8 based Canon iP4500 "on location" from my car's auxiliary outlet. The iP4500 can handle letter size (8.5 x 11") prints.
