5 INSTALLING PRINTER DRIVERS FOR UNIX/Linux
 Installing the CUPS for IPP printing
When you want to set up an IPP print queue in the Linux OS, follow the procedures here.
When IPP SSL is enabled on the equipment
When the IPP SSL is enabled on the equipment, you require the following settings on Linux OS.
 OpenSSL should be installed
 CUPS should be configured with "--enable-ssl" option
 HTTPS symbol should be created in the "/usr/lib/cups/backend" directory.
1. Open the console and login with root privileges.
- Use "su" or "sudo -s" to login with root privileges.
2. Enter the following command:
cd /usr/lib/cups/backend
3. Enter the following command:
ln -s ipp https
4. Restart the CUPS Service in Linux.
 IPP/SSL certificates in the "/etc/cups" directory should be created.
1. Enter the following command:
cd /etc/cups
mkdir ssl
2. Enter the following command:
openssl req -new -x509
-keyout /etc/cups/ssl/server.key
-out /etc/cups/ssl/server.crt -days 365 -nodes
 The above command must be entered as one continuous command with no carriage returns.
 The user will be prompted to enter country/state/province/locality/organization/organizational unit/
common name and e-mail address.
3. Enter the following command:
chmod 600 /etc/cups/ssl/server.*
* The "-nodes" option prevents the certificate and key from being encrypted.
The cupsd process runs in the background, detached from any input source; if you encrypt these files then cupsd will not be
able to load them.
4. Add the following lines in the cupsd.conf file in /etc/cups path.
SSLPort 443
ServerCertificate /etc/cups/ssl/server.crt
ServerKey /etc/cups/ssl/server.key
