Firewall

The printer server needs to communicate by the network, using the TCP/IP port number 5444. During installation an automatic Firewall rule is added to Windows configuration (the rule is created with program name “GefranPRNService”).If after some uninstallation or manual movements the program won’t work anymore, please try to uninstall and install again. Please even try to manually delete the firewall rule “GefranPRNService” before a new install.
