First check:
How does it look in "print preview". If everything looks fine here, it is a local problem (drivers/cables/ink etc)
If it also is broken in "print preview", do the following:
Send a mail to admin@chordie.com. You MUST include
a) the url to the song you are having problem printing. If it happens on "lots of songs", include the url for ONE song you are having problems with.
It is also great if you include:
b) a note about what browser you are using
c) a screenshot of your print preview (ctrl-shift-prtScr in Windows, and ctrl-v to paste it to your mail)
