Drupal 9 Entity Print Styling the PDF

I have installed already Entity Print in a Drupal 9 website. What I want is simple: style the pdf output in two views:
– One that is showing the details of an order (like a ticket or an invoice) and the other is to style the output of a view so that the fields can match into a certificate. (I already have the pdf´s for the ticket and for the certificate background) – is just to style and match the fields.
