I am allowing port 161 UDP traffic between the VLANs.
As a test, I allowed all traffic on all ports between VLANs and the icon still did not show up.
I also tried disabling the Windows Firewall. No change with the Windows Firewall disabled.
This issue occurs on all Windows PCs when a printer is on a separate VLAN. This issue occurs on both domain and non-domain PCs.
This issue only occurs when a printer is on a separate VLAN. This issue does not occur when the printer is on the same VLAN as the server/PCs.
We are using the same print driver throughout all of our testing. We are using the most current print driver supplied by the manufacturer.
The issue occurs on multiple printers from multiple manufacturers (for example, HP and Toshiba) when a printer is on a separate VLAN.
The issue occurs even if we add a printer (printer on separate VLAN) using a direct TCP/IP port on a PC/server on a different VLAN.
Since the issue occurs when firewalls are disabled and all port traffic is allowed between VLANs, I am wondering if we need to enable multicast between the VLANs in order for the printer icon to properly show up. Does this sound like a reasonable avenue to explore?
Thanks again.
