What's this button doing? Print/View options

Playing around with the View Options button (hoping to change the zoom setting of the print example, but that doesn’t seem to be possible), but except a flash on the screen, I can’t see what it is for:

I have not tried this yet, but it might produce extras, that appear on the paper printout (like cropmarks etc…)

This option surprisingly makes your View options appear in the print :laughing: These include signposts and voice colors.

Wasn’t obvious at all to me :stuck_out_tongue:
