How To Get Printout Of Text Messages? (iPhone 4)

I was just curious is it possible to get a printout of text messages? I don't really have a reason for them other than just to have them. Like if I call my provider (bell) would they do it? Or is it not possible? I am the owner of the phone though and do pay the bill.

Thanks! (Sorry if this is in the wrong area I haven't posted much on here)
