OrgChart for macOS supports to export organization chart as PDF, CSV, Image and OPML files. We can share the PDF, image file to other users without OrgChart installed, and using CSV file to be updated for other reporting/integration purposes, also export as OPML file to be opened in mindmap app (such as iThoughts) or other outline apps.
As the macOS devices have much stronger hardware resource than iOS device, by default OrgChart exports PDF in one PDF page. As macOS is much more open system, the PDF printing provides more options for printing, such as margin, zoom and etc.
Also we can google other 3rd printing tool to print large PDF file in multiple papers, for example using Adobe Reader (https://helpx.adobe.com/acrobat/how-to/split-pdf-document.html). Also there are many other tools we can use to split large PDF page into multiple pages.
