Reformat multiple HTML articles for printing

I loved to copy HTML articles and put them into a word document so that I can print them out without Adverts and junk and read them on the train.
I would like to be able to easily reformat the article so that all the text (Headings and Standard Text) are all the same font and proportionally sized.
Does anyone know of a tool that will reformat in the way that I desire.

If you're using Windows, copy and paste them into Notepad. It ignores graphics and formatted text. You can set the font you want and all of the article will appear in that font.
