Learn about Windows PowerShell
Summary: Microsoft Scripting Guy, Ed Wilson, shows how to use Windows PowerShell 3.0 to publish printers in Active Directory Domain Services (AD DS).
Microsoft Scripting Guy, Ed Wilson, is here. While I was studying for one of the tests for the new MCSE for server infrastructure, Exam 70-410: Installing and Configuring Windows Server 2012, I ran across the Configure print and document services exam objective, and I began to think about publishing printers to Active Directory.
Note Actually, the cool thing about Windows PowerShell on Windows Server 2012 is that nearly everything that needs to be accomplished is doable via Windows PowerShell. So, this actually becomes a bit of a problem for me, because I am not always familiar with the GUI utilities, or other command-line utilities. This is one of the real reasons that I like to take certification exams on our new products—it helps me to get to know the capabilities of the product, and it also gets me out of my shell (pun intended) when it comes to administration.
Well, anyway, because there was not much Windows PowerShell on the exam, as I would have liked, I thought it would be cool to do a little Windows PowerShell to solve some of the objectives.
To find all of the printers defined on the server, I use the Get-Printer function. The output, appearing here, provides the printer name, computer name, type, and the name of the printer driver.
PS C:\> Get-Printer
Name ComputerName Type DriverName

Unfortunately, the Get-Printer function does not have a –published parameter nor does it have very much filtering capability. To obtain a better idea of the type of information returned by the Get-Printer function, I pipe the output to the Format-List cmdlet, and I choose all properties (fl * is the alias). The command is shown here.
Get-Printer | fl *
The command and its associated output is shown here.
To find printers that are not published to Active Directory Domain Services, I need to use the Where-Object cmdlet to filter out printers that have a value for the published property that is equal to $false. I use the command appearing here.
Get-Printer | ? published -eq $false
When I run the command, I see that there are numerous printers that are not published to AD DS. The command and its associated output is shown here.
Now that I know I can find all non-published printers, I need to figure out a way to publish the printers in AD DS. Fortunately, this is pretty easy. I use the Set-Printer function. Luckily, the Set-Printer function has a –published parameter, and I can assign a value of $true to it. I arrive at the following command.
Get-Printer | ? published -eq $false | Set-Printer -Published:$true
When I run the command, a couple of errors arise. The command and its associated errors are shown here.
When I check to see if there are any AD DS published printers, I now see that there are three published printers.
PS C:\> Get-Printer | ? published -eq $true
Name ComputerName Type DriverName
The printers that generated the errors are the printers (such as the XPS document writer) that don’t make sense to share out across the network.
