RSS2PDF is a free web utility that lets you convert OPML or RSS feed to a PDF file. It’s very quick and created PDFs are nicely formatted for your offline reading pleasure.
To get an idea you may check out the converted MakeUseOf feed here. The link prompts you directly with a download option of MakeUseOf Directory feed in PDF format.
There is also an option to get the PDFs delivered to you via email.
