How can I print using kodak hero 5.1 wifi

Kodak does not make any Airport compatible printers which is why you can't print to it directly from your iPad. A Macbook Air will have not problem printing to it and if you install Printopia you can also then use your iPad.

You can use some of these apps to print to your printer from the iPad (as well as Printopia as deggie suggests).

Look on Kodak's site. They have several options depending on your model. Some use google docs and an online account.

I have a Kodak printer and the app 'print n share' and it works just fine, so a third party app may be your best bet.
