Translation of pdf invoice

Hi
What file do I have to translate to change the pdf invoice into a different language? ( Oxid 4.4.5)

the dynamic text (shop name, address, name, etc…) are from the Core Settings.

The other text such as “[B]Please always indicate for payments[/B]”, etc…)…try checking
[BOut->]Admin->En[/B] language file.

Search for the partial string… [B]ORDER_OVERVIEW_PDF[/B]
and you’ll find the static text.

I’m not sure how to handle multiple language version. Admin allows for “Create PDF in (language choice)”
