I'm not sure, but perhaps it is in the menu on your computer.
Be sure that the fan chart is centered on the monitor before selecting print.
I zoomed the fan chart. Dragged it as far left as possible then did a cntl P in chrome and changed to landscape more and it all fit on one 8 /1/2 X 11 page. You could experiment with how much to zoom and how far to drag to get the best display. For 7 generations it is difficult to read the names on one sheet.
