Then get CutePDF or whatever PDF Writer you want.

Then open the file in Snapshot viewer and save as .PDF

Most people have a PDF reader, most people don’t have the snapshot viewer.

As the snapshot is uneditable anyway, putting it into PDF shouldn’t be a problem. And you might even be able to edit the PDF if you have a full PDF package.
