How you would do this?
I'm trying to stylized a Prestashop Invoice. And it's tedious to complete for me, since I don't have a chance to preview it without printing it first to a PDF.
Is there any way to preview it without having to print it? I'm thinking of a way just like when debugging html pages with Chrome Dev or Firefox Developer tools.
This is on Prestashop 1.6.0.14
You can view the invoice pdf from backoffice. Orders->invoices->generate pdf by date.
