FPDF error when trying to create PDF or print

I’m trying to use this plugin to print entire product pages, but whenever I click on PDF or Print or Doc, it errors to a page that says:

FPDF error: Unsupported image type: com/chart

I’m not sure what this means, from my search it’s perhaps the image format so I’ve made sure the product image was a .jpg (still errored), then removed all images (still errored). The only thing left is the png logo in the top left of the site, and even then I tried to remove it through Inspect Element before clicking PDF.

Any support on this issue would be great; none of the other PDF/print plugins have been successful in showing the whole product page.
