This post look at some Printing and Active Directory concepts and troubleshooting. To start with, what we’re going to do is look at the output from LDIFDE for one of our printer objects. The command that we run is: LDIFDE –s <DC for the domain> -r objectclass=printqueue -f <path\filename>. I’m running this on one of my Windows 200x Server machines and pointing it at my domain controller. Printers that are published in Active Directory are published as a child object of the Computer object for the printer. The –s switch points to the Domain Controller for the domain. Printers that are published manually can exist anywhere in the AD as they are not connected to a computer object.
