Check firewall not blocking shared printing

Couple of quick ways to check if the firewall is blocking a shared printer.

From a remote machine open an command prompt and use

Net View \\print-server-name

This should return a list that includes the name of the shared printer generally you can now eliminate the network or firewall as an issue.

or download PortQry from Microsoft and check the required ports are open on the computer sharing the printer.

Use PortQry or PortQueryUI to check TCP ports 445 & 139

If computers are not on the same LAN segment don’t just check the print server firewall ensure their is not another firewall between the computers.
