Sometimes you just need information paper. In my case, I'm formatting wiki pages and research notes for a test of our infrared curriculum.
The default browser print mode produces a mess by displaying all the links:
You want to switch to "web style" and then select the rectangle shown, by clicking in the upper right corner of that area. That rectangle represents the main stream of content.
Once selected, press "Delete Except" and select "unrestricted" this will delete everything except the content of the note or wiki page.
That's it! Hit "preview" and then "print" to get a PDF.
Print Edit works on any web page too!
