Go to Tools > Export from inside your account, then choose the Printable HTML Table option under the What Type of Format Would You Like To Export? section. On the screen that follows, click the Open the printable list link. This will open a new browser window that you may print as you would any other web page on the Internet. Close this window when you're finished printing.
If you need help with the rest of the options on the Export page, please see this article.
