You may remember back in the day of Macintosh SE, System 6,  ImageWriter,  Claris Works  and so on that you could print across several pages on a Macintosh and easily make a banner.  That beautiful feature has been completely missing since OS X was introduced in 2001.
There is a way to print across multiple pages. Save  your document as a PDF file, open it in Acrobat Reader (it’s free), and from there you can print it across multiple pages.
