Getting The print servers in a network - powershell

Question

I want to write a PowerShell script to get all the print servers in a network.
I have used the following LDAP query, but it returns only servers with network printers attached to it. But not other print servers that have a remote printer attached to it.
Here's the code I used to get the print servers (But getting only the servers with n/w printers)
Import-Module ActiveDirectory
[array]$testarray = Get-ADObject -LDAPFilter "(&(&(&(uncName=*)(objectCategory=printQueue))))" -properties *|Sort-Object -Unique -Property servername |select servername
$testarray

Answer 1

You could try something like Get-WMIObject win32_printer | select name,local wrapped in a foreach-object loop like this:
$servers | ForEach-Object {
Get-WMIObject Win32_Printer -computername $_ | Where-Object {$_.local -like 'False'} | select Name,local,SystemName | format-table -a
}
The $servers can be what scoped to whatever servers you need to check.
Use Get-WMIObject Win32_Printer | select * to see what properties you want to report back on and include them in the | select Name,local,SystemName section of the script

Answer 2

You could use a combination of Get-ADComputer and Get-Printer to list all shared printer queues on computers joined to your domain:
Get-ADComputer -Filter * | % {
$computer = $_.Name
Get-Printer -Computer $computer | ? { $_.Shared } | select -Expand Name
}
This doesn't cover computers that aren't domain members, though.
