(That particular language was one I was using over 20 years ago and it 
was an integrated part of a CAD application (and it started off 
pre-Windows).

The app also supported printer/plotter/image destinations including 
PostScript. The same language could take a marked-up text file, convert 
it to a series of drawing elements, then render and print that page on a 
PS printer. Then the same with the next page. I think I did a 350-page 
manual like that. With pictures.

My current language doesn't link its 'print' to graphic displays or images.)
