Print Individual Email Message in Gmail Thread
Gmail's threaded messages are cool. But the link provided to print a message prints all the messages in the thread. There is a link to print an individual mail, which is somewhat hidden. So here's how to do it -
1. Expand the message you want to print by clicking on the subject.
2. Click the small drop-down (near Reply link) in the top-right of the message.
3. This opens a menu which contains a Print link. This will print the selected mail only.
