How printing works: the Overview tree (Nick & Mary through grandchildren) always prints as-is. On a grandchild's tab, only the branches currently expanded on screen get printed — collapse anything you don't want first. Printed sheets tile across as many 11×8.5in landscape pages as needed; each sheet break falls in the gap between boxes, so no box is ever split — a sheet may have a little blank margin on the right or bottom instead. Corner tick marks help you line sheets up when trimming and taping. Pages print edge-to-edge with no page margin. Use “Print all trees” to print every tab in one go (each in its current expand/collapse state) — a dashed divider page is inserted between trees so their sheets never get mixed up while trimming, while sheets within the same tree stay flush for taping. Green dashed lines on screen show exactly where a page break will fall — drag one to force the break somewhere else (it snaps to the nearest gap between boxes and never shrinks a page past 11×8.5in or a box/font size). Use “Reset page breaks” to go back to the automatic layout for the current tab.
