Hi. It seems that the only way to adjust the font size of the bar based lyrics in printing PDF, is in Print Options: font size (def.) = 24. It effects both to the chord letters and the lyrics so it takes a lot of pages to print a song, because trying to compress them to just like two pages the chords and lyrics go over each other.
It can be adjusted how far away from the ledger the lyrics are "Lyrics Below By", but not the chord symbols.
Or has someone found other solution?
