It all depends on what you’re printing. This is an unfinished visualization of
Diggsey’s Trigonometry Tutorial, I played with a while back. Set the display setting to - Windowed (1024 x 768). Media is attached. The code uses both text and print commands. You can see how using text in place of print, would only add unnecessary code.
