Bad layout for PDF invoice

Hello,
the PDF version of the invoice generated and linked in the Registration history is not automatically resizes to the size of a sheet of paper, e.g. DIN A4 size used in Europe. The right part is cut off.
I use a Joomla 3.5.1 site for testing, with only Event booking as component.
I do not find where to set printer layout parameters.

I would appreciate any advice.
Sincerely
Léon

Hi

Could you please upload a sample invoice you downloaded here? Did you change anything or using the default invoice layout?

It works well here for us (and for other customers)
