Looking for a digest/post collection plugin

Amongst other things, I use my blog for journalling and every so often I need to submit my journal for scrutiny. Is there a plugin that would allow me to collate particular blog entries and, optionally, their comments and create a pdf or printer-friendly page of everything?
And before anyone else points out the obvious, I’ve already suggested it gets read online, but apparently that’s not an option.
Many thanks,
John
