Weird issue with PDFs

I've been using the "Print" module to create PDF "print versions" of some pages. It was working fine, and then when I started using Wabi, I started having problems with it. Previously, the PDF that was created would have text that filled up the whole width of the page. But when I use the Print module in Wabi, the PDF displays the text in one skinny column in the middle of the page, so that it takes several pages to display it. I even tried editing the column widths in Wabi's CSS file to see if that made a difference. It made a difference on the site itself, but not on the PDFs that were generated from it. Has anyone else had this issue with this theme?
