Slate takes on printers that lie about toner

As a certified cheap-skate librarian, I was tickled pink to run across the Slate article linked in the title of this post. Click on the title to read about how printers often lie about when their toner is running low. And even better, for links to hacks on the web that will help you (and your library users!) to run the toner cartridges dry before you have to replace those pricey cartridges. Covers a lot of differnt printer types.
