CentOS 7.x Configure cups printing server

To configure cups print server on CentOS 7.x use following steps:

yum -y install cups ghostscript hplip-common
In case there is no real printer for testing and you want to use a virtual printer for practising cups then also do:
yum -y install cups-pdf

Start, enable and check status of cups services

systemctl start cups
systemctl enable cups
systemctl status cups

Configure cups to be accessible on LAN by editing '/etc/cups/cupsd.conf as follows:
1. Prepend following at begining of configuration file
```
DefaultEncryption Never
```
2. Add additional 'Listen <lan-ip>:631' directive along with other 'Listen' directives to listen on additional IPs (non-loopback)
3. Edit access configuration for <Location /> to give access to others to cups print server
4. Edit access configuration for <Location /admin> to give admin access to admin station IPs
5. Restart cups for changes to take effect
```
systemctl restart cups
```
Now cups can be accessed at https://<lan-ip-or-fqdn>:631/ from IPs whitelisted in the access configuration
To add the printer on any other Linux machine over IPP use printer URL such as:
```
ipp://<lan-ip-or-fqdn>/printers/<printer-name>
```
For example, 'ipp://192.168.123.91/printers/cups-pdf' can be used to access cups-pdf printer setup on 192.168.123.91 machine.
