Most of my old printed transcriptions were done in SuperPaint, now a long defunct graphics program for the Mac. Every now and then I want one of those old charts and need SuperPaint to open them. Fortunately, I still have a Mac that can run it. Once open, I can save the file as a TIFF which I can then import into a more modern program to export as PDF. Meanwhile, all the photo copies I made and original laser prints still look fine – technology changes fast, paper not so much. So if you want a document to last, print it!
