Use this tab to display the access control list (ACL) on the HP Jetdirect print server. An ACL (or host access list) specifies individual host systems, or networks of host systems, that are allowed to access the print server and the attached network device. You can add up to 10 entries. If the list is empty (no hosts are listed), any supported system can access the print server.
Not all print servers or devices support ACL, and support is limited to IPv4 networks. For improved security and performance, use the IPsec/Firewall feature (if available) instead of ACL.
By default, hosts with HTTP connections (such as, the embedded Web server or IPP) can access the print server regardless of access control list entries. To disable HTTP host access, clear the Allow Web Server (HTTP) access check box at the bottom of the list.
You can lose communication with the HP Jetdirect print server if your system is not properly specified in the list, or access via HTTP is disabled.
To use the access control list as a security feature, see Security features (V.38.xx).
Specify host systems by their IPv4 address or network number. If the network contains subnets, you can use an address mask to identify whether the IP address entry designates an individual host system or a group of host systems.
