Print preview with description of the group

[n-houdini]

Is your feature request related to a problem? Please describe.
I think the printout of a group or event could contain more information than the names of team members.
Sometimes we give to the leader a sheet with the elements and it is necessary to add more information about an event. That information is on description of the team or on description of the event of the group.

Describe the solution you'd like
I would like a group description or Events/Meetings description to be able to appear in the print preview in the header, along with the list of members
