Ever tried to install a printer by just giving users a link? Well here is a small snippet of one way to do this. Please note that since you are interacting with the OS (outside the browser) that you may receive security warnings. This has been tested on Vista SP1 x86 32 bit with IE7.
Set WshNetwork = CreateObject("Wscript.Network")
<a href='#' language="vbscript" onclick="AddP('\\Home-PC\HP Photosmart 3300 series')">Add printer</a>
Please note that above the a href should be ="#" not single quotes.
