I know when I have been to a blog and have seen a piece of information that I wanted to keep for future reference, or as a guide, but when you go to print it or save it as a PDF, it just spits out pages of gibberish, the photos are all crammed into one corner. It is just a waste of paper.
To stop this happening here, I have installed a new tool, called PrintFriendly. So if you open a post you are interested (as a separate post, not in the blog feed), then you will have a couple icons come up, giving you the option to print the post, or save it as a PDF. All free, and free of ads too. I hope it saves some hassles as well as saving some trees.
