Sorry for the late reply. Ive been very busy lately.
Yes, I can reproduce the problem. I am however not 100% sure how to fix it.
The problem is really a browser bug, and the chords are written outside the print-area in the browser.
I will do some experimenting here with different css setting.
Here is something that MIGHT work in the meantime (have not had time to test):
* Another browser (Firefox)
* Try turning off top-bottom-header in the print dialog
* Set top-bottom-margins to 0
