Change the font on your Kindle without hacking it

That’s the title of an article at Chris Walters’ Booksprung blog.  Here’s a snippet:

I finally updated my installation of Calibre the other day and started playing around with the built-in plugin manager under Preferences, and I found out that the Kindle Collections Manager plugin has a secret power: it can let you add a new font to your Kindle without requiring any sort of hack or jailbreak. If you want a different font but don’t want to mess with all the other risks/delights that come with hacking your Kindle, this is a nice clean alternative.

To use it, you’ll need the most current version of Calibre, and you’ll need to go into Preferences, scroll down to the green puzzle piece icon, and enable the Collection Manager plugin. The plugin you want is called “Kindle Collections”.
