Hi Kathryn,
on my site I’m using Writr version 1.0.8:
organspenden-macht-sinn.de
“Home” content is presented by a page, not a post.
I changed some basic colours (style.css) and commented out the comments template. I first thought the printing error is a result of my changes. So I checked all modified files by file comparison and couldn’t find the fault. Then detected the same issue with the demo version …

where “Home” and pages of “Recent posts” show empty previews, too.
“Parent page” and its childs behave a little bit different from “Home”, at least there is a header and a footer provided by the printer/spooler.
