There are times when you need to print stuff from a site you visit. However, printing from some sites can be a really painful experience in that the printout tends to come with all the ads and images on the page. PrintWhatYouLike is a nice tool that helps you choose any portion of a webpage for printing.
All you have to do is enter the URL of the page you want to print and select the portion of your choice. You also have the option of saving a page as a PDF or HTML. There is a bookmarklet you can add to your browser to make accessing the tool easier.
