Looking for the best app for printing from my iPhone 6+

I am a smart phone neophyte, 91 years old, and want to print my appointment calendar from my new IPhone 6+. I usually go to web sites where user reviews are available. At the I tunes site 18 printer apps was displayed. Truthfully, i did not know what to click on without a little knowledge about the capabilities of the app. How to get reviews??

All you really need is a printer capable of Apple AirPrint via wifi... After that, you print from any app capable of printing.
