[otrs] Editing the PDF templates

Hello all, When printing an article or ticket, I have the PDF feature enabled, and it works well. I would like to edit the PDF templates beyond changing just the logo image. I've searched through source files and Google with no luck, how can I edit the low level formatting/templates of these output PDFs?
