# Configuring NPrinting

This topic pertains to the setup of NPrinting to allow for NodeGraph calls.

For production, a separate postgres user should be setup for NodeGraph use.

## Open POSTGRES for External Connections

If NodeGraph and NPrinting servers are installed on different machines, the NPrinting PostgreSQL instance needs to open for external connections.

The configuration files are located on the NPrinting server under:

%ProgramData%\NPrinting\data\

In the file postgresql.conf: uncomment or add listen\_address with a \* value:

Listen\_address on postgresql.conf

Listen\_address on postgresql.conf

Listen\_address on postgresql.conf ![The Listen addresses, found below the Connection and Authentication label.](https://help.qlik.com/en-US/nodegraph/Content/Resources/Images/NodeGraph/ui-NodeGraphTD-115.png)

In the pg\_hba.conf file, add a host entry to allowlist the NodeGraph server IP:

Allowlisting NodeGraph server IP

Allowlisting NodeGraph server IP

Allowlisting NodeGraph server IP ![The host entry, with fields for the database, user, address, and method.](https://help.qlik.com/en-US/nodegraph/Content/Resources/Images/NodeGraph/ui-NodeGraphTD-116.png)
