In windows Vista and Windows 7 when you add a network printer you get a dialogue box that looks like you should be able to select the printer from the list but the list says that there are no printers available. After much hunting I finally found some group policy settings that change how things are listed.
This how to shows where to go to change the settings
Open Group Policy Management Console
There are many ways to do this so use your favorite way.
Create a new Policy
Create a group policy in in the Organizational Unit where your computers are stored.
Browse to the relevent section
So this is what you all are waiting for:
Computer Configuration>Policies>Administrative Templates>Printers> Add Printer wizard – Network Scan Page (managed network)
This GP setting allows you to determine how many of the following printer types show up.
Other things to look at since you are here anyways
Some other settings that may be of interest to you as well are
Point and Print Restrictions (allows you to allow your users to add printers from set print servers without having a UAC prompt)
Printer Browsing (I am not sure if you need to configure this but I did just in case)
I hope this helps some one else figure out how to add information to the the “Add Printer Wizard” dialogue box
I wish I still had the references for how I figured this out. I think I got the hint somewhere in the Spiceworks Community but I am not sure where it was anymore.
