iFly is really intended to be used on an electronic device in the cockpit, with the ability to pull up a myriad of information literally at your fingertips. It's not really designed at all to transfer any of that information to paper in the form of printouts.
If you would like to have hard copies of some of your flight information, it's probably better to use a companion tool that is better focused on providing such a feature. For instance, the AOPA flight planner used to do a good job of providing a graphical route printout if you wanted one, though I haven't used that tool in a long time and don't know if it still does (and it requires an AOPA membership to use).
I like to use fltplan.com to print out a nav log before flights. It doesn't have a good graphical route feature...but that's what I use iFly's live display in the cockpit for.
