If like us, you have a cluster as printer server, you have noticed that you can't dump printer info from wmi. This is referenced at Microsoft.
Else, you can dump them if they are published in Active Directory.
The following script works great on a W2K3 AD (with a W2K3 cluster):
Const ADS_SCOPE_SUBTREE = 2
Set objConnection = CreateObject("ADODB.Connection")
Set objCommand = CreateObject("ADODB.Command")
objConnection.Provider = "ADsDSOObject"
objConnection.Open "Active Directory Provider"
Set objCommand.ActiveConnection = objConnection
objCommand.CommandText = "Select printerName, serverName from " _
& " 'LDAP://DC=mydomain,DC=com' where objectClass='printQueue'"
objCommand.Properties("Page Size") = 1000
objCommand.Properties("Timeout") = 30
objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE
objCommand.Properties("Cache Results") = False
Set objRecordSet = objCommand.Execute
objRecordSet.MoveFirst
Do Until objRecordSet.EOF
Wscript.Echo "Printer Name: " & objRecordSet.Fields("printerName").Value
Wscript.Echo "Server Name: " & objRecordSet.Fields("serverName").Value
objRecordSet.MoveNext
Loop
