At one time, I used to tile the printing which means that it would print on multiple pages when margins were exceeded and you could cut and paste the pages to get a full ring. I got a lot of grief from because this meant that each row would print four pages of color and printer cartridges are expensive. I first switched to scaling the ring to fit the printed page but that brought an equal number of complaints because customers used the full size printout to double-check their saw cuts.
If you are making painted segment projects, you should consider using Segment PRO. I added the Ring View to provide exactly what you are looking for. Segment PRO is also far superior for painting vessels. There isn’t a way to transfer plans from one software to the other because there is almost no commonality in how the data is stored or used in the two programs. The two programs were developed for two very different purposes - Segment PRO makes it fast and easy to make standard segmented vessels and Woodturner PRO allows you to do anything you can imagine, including staves, compound segments, wheel configurations, etc. You can make the same painted segments vessels you can make in Segment PRO, it will just take you a lot longer and you will not have access to some pretty cool tools.
