Hi all,

If you have a printer connected to a PC and share that printer to others, if you then go to another PC and install the printer, it treats it like a network share and only installs it for the user you are currently logged in as...

I needed to install one such printer and then I wanted the printer to be installed and available for whoever logged in...

With this in mind I recently found a rather nifty trick to install the shared printer globally on the machine by doing this from the command line..

rundll32 printui.dll,PrintUIEntry /ga /c\\%COMPUTERNAME% /n\\Name of target PC\Printer Share Name

The /ga switch installs the printer globally to the system and is not available on the GUI...

This all got me wondering... how does Windows actually use rundll32.exe in the GUI... or does it not (Sorry if thats a very vague question)
