Hi Rdub.
Welcome to the forums
Most piano Realtracks have notation. Piano MIDI tracks also have notation. If you load one of these Realtracks or MIDI tracks and generate the song, it is possible printout the notation using "Leadsheet". How easy the piano part is will depend on the Realtrack (or MIDI track). Some Realtracks have a "Simple" option when they're being generated. This creates a performance that is less embellished.
After you have entered the chords for your song, what I suggest is...
1) Open Multipicker Library (#1 on the image below) and select the "Realtrack" tab.
2) Click on the "Filter String" (#2) and type in "Piano" so that BIAB shows only those tracks that have 'piano' in their name.
3) Select a suitable piano track (#3).
4) Click on the "Settings" button (#4) and select "Simpler" or "Held" (#5, #6)... these two options may or may not be available. It depends on the Realtrack you've chosen.
5) Exit Multipicker Library.
6) Generate the song.
After the song is generated...
7) Go to the Leadsheet mode.
8) Make sure the 'Piano' track is selected (#1 on the image below).
9) Select the "Opt" button (#2).
10) Make sure that "Autoset clefs" is active.
If the song has been generated, you will now see a piano part that can be printed out.
I hope this helps.
