How do you print from iPad if your printer is not an "Airprinter"?

Your printer manufacturer may have options. You'd need to look on their site for that. Or there are third party programs to allow printing. I use Print N Share, there's also print central or printopia and i'm sure there are others.

the biggest caveat is that it needs to be a wireless printer.
