Have you ever tried to print a List in SharePoint. Well first you have to export it to Excel then print it. Yuck! Well there is a better way. Check out the link below.

This is basically a feature that installs a Print List link in the Action menu. The List then opens in a print preview mode. I do wish the author would have packaged it up as a wsp but the steps are pretty clear. In fact I've been doing some developer training on deployment lately and I might use this article to show what a wsp actually does when installing a feature.
