Ports
Qlik NPrinting uses the following Transmission Control Protocol (TCP) port numbers.
Security
-
QlikView ports are not encrypted. They are standard QlikView ports.
-
Database connections are configured to be local connections only. For example, you can only connect to the PostgreSQL instance that is running on the same computer. You should not change the PostgreSQL configuration.
-
Firewall rules require that external access to the webengine is closed.
-
Connection for certificate exchange is in plain text, but the message itself is encrypted.

Changing the default ports
By default, the Qlik NPrinting web console is set to port 4993. The NewsStand is set to port 4994. These can be changed by editing the webengine.config file. This file is typically located under: C:\Program files\NPrintingServer\NPrinting\Webengine\Qlik.NPrinting.Webengine.config.
Do the following:
- Stop the Qlik NPrinting web engine service.
- Open the webengine.config file in a text editor.
- Update these strings with your preferred port values:
- <add key="webconsole-proxy-port" value="4993" />
- <add key="newsstand-proxy-port" value="4994" />
- Save the file.
- Start the Qlik NPrinting web engine service.
