Sample ACL settings:
Not all printers offer the Access Control List (ACL)
interface. If this option is available, I
strongly encourage you to utilize it. The
ACL determines which IP addresses the print device will accept print jobs from.
In the image below, you see that the IP address is, 192.168.0.0, and I have 128
nodes, then my subnet mask is, 192.168.0.127.
