I've not seen specific instructions for CentOS 7, but when I last did 
this the actual AirPrint script was simple enough that I doubt you'd 
have trouble. Main thing is making use that you can print directly from 
your CentOS machine.

Depends how the network is set up. I had my AirPrint server on a 
different VLAN to the wifi, and you need the following for that to work:
An Avahi bridge so the announcements from AirPrint are also announced on 
the WiFi
Firewall rules to allow the CUPS port through from the WiFi to your server

I found this was pretty easy to configure, but I was able to completely 
control the network (putting VMs on any VLAN; opening firewalls etc.). 
It might be easier to use wifi in your setup.
