PREPARING FOR EX PRINT SERVER SETUP 20
Additional security features
In addition to the traditional security features such as passwords, you can use these features to
keep the EX Print Server secure:
•E-mail access
• IP addresses, ports, and MAC addresses
• Secure Printing
• LDAP authentication
Controlling E-mail access to the EX Print Server
Because you can allow users to print file attachments in e-mail messages sent to the EX Print
Server, the EX Print Server accepts only valid attachments (for example, PostScript or PDF
files). Typically, viruses transmitted via e-mail require execution by the receiver. Attachments
that are not valid files are discarded by the EX Print Server. Because file types such as .BAT,
.VBS, and .EXE could launch harmful virus activity, the EX Print Server does not process
these file types. The EX Print Server also ignores e-mails in RTF (Rich Text Format) or
HTML (Hypertext Markup Language) format, and any included JavaScript code.
You can define lists of authorized e-mail addresses on the EX Print Server. Any e-mail that the
EX Print Server receives from an e-mail address not in the authorized list is deleted. For more
information, see page 42.
Restricting IP addresses, ports, and MAC addresses
To restrict unauthorized connections to the EX Print Server, you can permit only users whose
IP addresses or MAC addresses are within a defined range. You can also close unnecessary
ports to reject inbound access from the network. Commands or jobs sent from unauthorized
IP addresses or ports are ignored by the EX Print Server.
Secure Printing
This option allows the printing of highly sensitive or confidential files with user
authentication. A user printing a file with the printer driver assigns a password to the job. The
user must then enter the password at the press to print the job. You assign passwords in
Configure using Users and Groups. For more information about assigning passwords to users
and groups, see Configure Help. For more information about how to print a secure job with a
password, see Printer Driver Help.
LDAP authentication
When you enable LDAP communication to retrieve names and other information for people
at your organization, you can specify the type of authentication. For more information, see
Configure Help.
