LP printing problems

[Dave Phillips]

Greetings:

 I've written some music for flute, guitar, and harp, it's on-line at 
http://linux-sound.org/dlp-music-lilypond/gfhtrio4/gfhtrio4.html. The 
score is naturally three staves (the harpist is a novice, her part fits 
in a single clef), and the printout is lovely. Alas, the printout is 
also cutting off the last staff from each page. The printing continues 
at the start of the next page, i.e., the missing staff is simply gone 
(not continued on the next page). My question: How do I solve that 
problem from LP ? Is there a \paper directive I should use ? If so, 
which one ? Or is this a printer problem ?

 The printer is a recently acquired HP 6540, it's fast and its output 
is excellent. I'm hoping the problem isn't with the printer. :(

 Second problem: The printout is a little too small for some of 
students, how can I adjust the size of the printed elements ? Again, is 
there a global LP command that will print everything in a larger font & 
text (and handle the page breaks appropriately) ?

Best regards,
