We found another printing issue from the forum. See details below:
You have a Windows Server 2008 R2 as printer server. You use Windows 7 as a client to remote manage the printers. You opened Printer Management Snap-in and added the printer server. But you found the printers are not showing up, drivers, forms and ports are there but no printers.
You even went ahead and turned the firewall off completely, but no luck.
The possible cause is client system (the system running Printer Management Console) does not have a DNS A record (forward lookup).
To resolve it, add a DNS A record for the system that running Printer Management Console.
