●

Import an HP Jetdirect certificate and private key. When imported, the existing certificate and private key are

overwritten.

The file format must be PKCS#12 encoded (.pfx).

To import a certificate and private key, specify the name and path of the file that contains the certificate and

private key. Or, click Browse to browse your system for the file. Then enter the password that was used to

encrypt the private key.

Click Finish to complete the installation.

Export the HP Jetdirect certificate and private key screen. Export the installed HP Jetdirect certificate and private key

to a file.

●

To export a certificate and private key, enter a password to use to encrypt the private key. Enter the

password again to confirm it. Then click Save As to save the certificate and private key in a file on your

system. The file format is PKCS#12 encoded (.pfx).

Access Control

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.

NOTE: 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 HP 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.

CAUTION: 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.40.xx) on page 121.

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.

Examples:

IP Address Mask Description

192.0.0.0 255.0.0.0 Allow all hosts with network number 192.

192.1.0.0 255.1.0.0 Allow all hosts on network 192, subnet 1.

192.168.1.2 Allow the host with IP address 192.168.1.2. The mask

255.255.255.255 is assumed and is not required.

To add an entry to the access control list, specify a host using the IP Address and Mask fields, select

the Save check box, and then click Apply.
