A different song prints than the one I wanted

The error lies in the fact that you have the a different song (usually the 1st song in the list) selected.

Go to the Songlist Page view.

The selected song is indicated at the far left border by a black highlight box.

Make sure you have the desired song selected before you try to print.

Another method would be for you to first do a find for just the song and transposition that you are after.

That way there are no other songs to interfere with the printing process.
