At first glance, the HP Blog Printing plugin for Movable Type and WordPress seemed rather pointless to me. Then I used it. All I can say is wow.
Typically, if you were worried about how your content might look when printed out, you’d create a print stylesheet that would control, to some extent, how things look when they print out. The HP Blog Printing plugin eliminates that problem, by allowing users to create an easy-to-read, printer-friendly PDF of your latest content on the fly. Best of all: it’s free.
For those of you who don’t have a site powered by Movable Type or WordPress, it might be worth looking into Tabblo Print Toolkit (developed by HP). By using a bookmarklet while viewing one of the supported sites, you can generate a PDF of the current page content.
I’ve now incorporated this feature into the website. You can access it via individual posts in the sidebar. Hopefully you’ll find it as useful as I have.
