The plugin does not affect the language.

But the ‘edit public profile’ (still) has a similar appearance to the old look, but it is not possible to set/choose a language for the public page.
Therefore, if you were to use that page as the basis for making it printable I would not be able to get it in danish (or any other language than english).

The current profile page is however IMO a mess and almost nothing is visible without expanding something.
But I supposed the profile page would be the one to use for the plugin, if people are to be able to choose a language.
