> Regardless if annotations are supposed to be printed or not on the PDF, would
> it not be interesting to possess a flag allowing to choose if annotations
> should be printed on top of the document pages?

> Here is a diff of a very rough implementation of it :

> By default, this would be keeping the same behavior as it used to (aka :
> print the annotations) but possess an opt-out feature.
