With version 1.7.0 we introduced print templates. You can create for example an easter or christmas banner, set a from and until date and users can create a PDF with this template. Templates can be enabled in general settings > enable templates.
In the menu you can then create templates including a title (template name), description (content for the template) and a from / until date.
The user can then, if date fits select a template in the fronted.
Content then gets added to the PDF. See the eastern banner example.
