I have found an extremely useful blog for teachers. I think it is my favorite one to follow. Here is the link: http://www.freetech4teachers.com/ You can subscribe to it also. Here is the lastest tool I plan to use and what the author of the blog, Richard Bryne, has to say about it.
PrintFriendly
"If you have ever wanted to print an article from a blog or a website, but wish you could do it without printing all of the ads and widgets in the side columns, you should take a look at PrintFriendly. PrintFriendly strips away all of the ads and side bar content allowing you to print only the article on the page. There are two ways to use PrintFriendly. You can copy and paste an article's url into the PrintFriendly homepage or use the PrintFriendly bookmarklet. I tried it both ways and much prefer using the bookmarklet as it doesn't require any toggling between browser tabs or windows."
