iPad Print HELP??

[Bergie]

I am new to the iPad forum and I am hoping that it can help me with some of the questions that I have. I recently added the iPad print app to my wonderful iPad. However I am having difficulty seeing what benefit the the app gives me if I cannot print some of the documents that I create while I am working on the iPad. Can anyone help me figure out how I can print a spreadsheet that I created in Numbers on my iPad without sending it to myself and then printing it from another computer? Thanks. Any help would be greatly appreciated.
