Plummiegirl,
I've been using rootsmagic for years and you can adapt and fiddle with the tree print format very easily. I took copies over to Ireland last may and had several people in the archives and GRO ask me how I printed them.
I agree with F&F though, the older programs are better than the newer versions. Don't know what the developers do with them but their fiddling is annoying and no real improvement.
A "cheap" printer to print continuous sheets would be wonderful, I had a very old printer that would do it once - before I started FH and had no need for that facility

even if I still had it, I doubt if there are current drivers for it.
