How to capture the visible page screenshot in one step in Safari or another browser?
So after a bit of playing with various options, I've come up with a pretty efficient solution:

I've found that even though it's older, using Paparazzi is the most efficient solution.  I was able to set some sane defaults for the file naming (using YYYY-MM-DD as a base) and the output resolution (around 1020 (width) x1320 (height) for ~120ppi (kept font size output for my monitor resolution at about the same size) letter (8.5"x11") gives me a nice ordered image output that I can then import into PDFPen or Preview, etc. to generate a nice sequential PDF from the output.

This leads to a simple navigation from page to page and a quick cmd-s + &lt;ENTER&gt; to save the image rapidly.
