Inkjet printer would be fine. Anything that uses powdered toner like a laser printer would not work. The initial heatup of the fusing roller draws LOTS of power. I have a Canon printer/copier/scanner/fax in my MH that draws something like 45W. I have run it in a pinch on a 400W MSW inverter with no apparent damage to either.
