I am using Commerce Invoice and Entity Print to generate .pdf-files of invoices. In Entity Print settings, I set the paper size to A4 and selected TCPDF as printing engine.
Then, I customized commerce-invoice.html.twig to my needs, which works fine.
But I cannot get rid of the two black borders that seperate the document header and footer I think.
Would be nice if anyone could give me a hint where these come from. I alread also tried to override entity-print.html.twig and remove the styles from there. Also I unchecked the checkbox in the entity-print settings.
But these borders still appear on every .pdf-generation.
Thank you very much in advance!
