Seperate packing slip styling

Hi support,

I am running a two language webshop (German and Dutch), so I want to make packing slips for German and Dutch orders. But we, as a company, have different a4 papers for these two languages. (the slogan under the logo and the contact information is different)

Is it possible to have the German a4 paper as background for German order packing slips and the Dutch a4 paper as a background for our Dutch order packing slips?

I already do have the following css code to add a4 paper as background: <div style=”position:fixed; z-index:-999; top: -1cm; left: -2cm; height: 297mm; width: 210mm; padding:0;”></div>
But this code is now also on German packing slips.

I am using WooCommerce PDF Invoices & Packing Slips, WooCommerce PDF Invoices & Packing Slips Premium Templates and WooCommerce PDF Invoices & Packing Slips Professional.

Thanks in advance!
