I struggled with this problem as the tree got bigger. I was unhappy having to print several pages and then taping them all together
Staples has a great service that allows you to save as a PDF and then print it at their store...they have 81/2 x 11 11x17 and in the printers...there were about $1 for a color copy
These were too small to see the names and dates well so I had them print it on a poster size..The tech at the counter was most helpful in helong me scale it up so I got maximum chart and minimum blank space. This was about $4 for a color copy.
