Hi jjjensen, you’re welcome 🙂
my idea is progressively adding more filters for adjusting that kind of things via functions.php in themes, but right now this is only possible doing a plugin template customization, more info here:
http://wp.dinamiko.com/demos/dkpdf/doc/how-to-use-dk-pdf-templates-in-your-theme/
In your case, once you have dkpdf-footer.php copied in your theme, you can add font-size to the main container for example:
<div style="width:100%;float:left;padding-top:10px;font-size:10px;">
Cheers.
This is working. Great, dinamiko, thank you!
