When you save the Pharos Server Settings, If the settings is correct and the Pharos Server (Edi) can be connected correctly, the Pharos Server is automatically allowed to access the printer (since the printer server is most likely on the same Edi server).

When you view the Status -> Network status page, the Pharos server should listed in the "Computers allowed to access the printer"text box.

The current release requires a reboot to take effect! Without a reboot, the Pharos server is not listed the text box and is not allowed to print to the printer.
