Auto Generating and Printing PDF Files From Markdown?

I'm looking for a way to automatically have my computer generate and print PDF files from a folder full of markdown files.

So, every morning at 5AM I'd want my computer look at my /markdown-files folder, create a bunch of PDFs to go into a /PDF-folder and also run the printer so the pages are waiting for me.

There are a couple of requirements that might make this a bit tricky:

1) The PDFs should have the file title at the top of each page

2) The lines should be double spaced at least.

I used to use WKPDF to accomplish this, but it no longer works on Yosemite.
