I see that you have changed "Share This" for "Print Recipe", so maybe that's what you meant (to rename the button). Nice website btw! The brown sugar toffee cake looks delicious :-)
In regards to your question about printing only the recipe and not the post too, I can think of two solutions:
a) your visitors could highlight the recipe and then press Ctrl+P (or go to File, Print) and select to print the "selection" instead of "all"
b) replace the print option with something like PrintFriendly.com, where users can remove items, like pictures or entire paragraphs, before printing. I chose that option for my blog.
