When a TCP connection (or any type of connection, for that matter) is forcibly closed by the remote host, you have one of two possible causes:
- A firewall or router is denying the connection using the application's TCP socket. In this case, that application is LPR and the socket is TCP port 515. So check between the server and the printer, and ensure that each router is allowing TCP 515 traffic. Also check, if the profiles are enabled, your Windows Firewall settings on the Uniprint print server.
- The printer is not configured to support the LPD application. Consult your printer's documentation to determine where to find the LPD function and determine its configuration. The LPD function on the printer must be enabled.
I hope that this helps,
Thank you Scott that was helpful~ problem solved and system is working as per expectations.
Appreciate your help and support.
You're welcome! Which one of the two was the issue?
