How can I set up my iPad to print to my Kodak ESP 7250 wifi printer

You will need a 3rd party app from the app store. I use print magic, which works with my Kodak 7250, but there are several other printing apps so check them out to see what suits you.

Kodak has a firmware upgrade to allow a version of air printing via a third party service, google docs I think. You can e-mail documents to your printer, or you can set up a hardwired printer as a local print server and send them to that.

Or you can look into an app. I have that same model of printer and use Print n Share and it works fine...slow but fine. I didn't go for the firmware cloud printing simply because I didn't want yet another online account.
