This is something missing in both Apple’s text edit and DT.
The insert page break command.
I have to print what I write in DevonThink and it would be far easier to get things formatted if I could insert page breaks like you can in MS word.
Page breaks are already on our to-do list (and targeted for v1.9) but it’s not yet clear if there’s a way to add this to Apple’s text engine. If this should be a major effort or require an own engine, this feature would be dropped.
